The Moto G 2015 and SD cards - everything you need to know

Your new Moto G 2015 has a microSD card slot for expandable storage. That's not exactly uncommon to see in an Android phone, though other makers are moving away from the practice. It's also going to become more important when Android 6 brings new (and arguably better) support to let external memory become more integrated into the system itself.

This is a perfect time to learn a little bit more about SD cards, and specifically how they work with the Moto G 2015 and what to look for when buying one. Let's take a look!

SD card file systems

SDHC vs. SDXC

Motorola lists the Moto G 2015 as having support for microSD cards up to 32GB in size. That's not just a random number picked out of thin air, and corresponds directly to the capacity supported by the various standards for Secure Digital storage.

Regardless of the physical size of the SD card (we'll look at that in a bit) your SD card adheres to one of three different standards for capacity.

  • The SD standard supports cards with up to 2GB of storage, using the FAT 12 or FAT 16 file systems
  • The SDHC standard supports cards with up to 32GB of storage, using the FAT 32 file system
  • The SDXC standard supports cards with up to 2TB of storage, using the exFAT file system

The file systems that are part of the standards aren't the only file systems supported on removable storage, but they are the file systems supported natively by Microsoft Windows which is found in most desktop computers. Devices — like our phones, or cameras, or digital music players etc. — use these file systems for removable storage by default so that the removable media can be removed, then inserted into your personal computer to access them. Android doesn't need to use any of these standards, but we use them for better compatibility.

SDXC cards are pre-formatted with the exFAT file system, and usually have a reserved area for DRM. Microsoft doesn't publish the specifications of the exFAT file system, and instead requires a device maker that uses it to purchase a license. Windows XP (SP2) and later, as well as Mac OS X 10.6.5 and later support the exFAT file system natively. If you're using an alternative operating system on your PC — like Android or BSD or Linux — you'll either need to do a few things to add support, or reformat the card with another file system and risk losing compatibility with some host devices that expect any SD cards over 32GB of storage to use the exFAT file system. Most companies who make our phones and tablets have just purchased the license and use SDXC to make things easy on us users.

If you want to get really nerdy, Google up some information about FUSE modules and how they work to read SDXC formatted media. I suggest a supply of adult beverages be at hand.

SD card form factors

SD card form factors

An SD card can come in one of three standard sizes. The size does not determine the capacity, though the naming convention can cause a bit of confusion.

  • The full size SD card is the largest version. You've likely seen full size SD cards, especially if you have a digital camera of some sort or another. SD cards support the SD standard, the SDHC standard and the SDXC standard.
  • The miniSD card format is fairly uncommon. It's an in-between size, and requires it's own type of card slot because it has two extra input-output pins compared to the full-sized SD card format. The miniSD format supports the SD standard and the SDHC standard.
  • The microSD card format is the size we use in our Androids. About the same size as a SIM card, they fully support the SD standard, the SDHC standard, and the SDXC standard.

You might have seen microSD card to SD card adapters, and this is possible because both full-sized SD cards and microSD cards share the same pin layout. The only real difference is the physical size of the plastic shell, and that full-sized SD cards can support a write-protect switch.

If you're buying a new (and expensive) SD card I suggest you buy a microSD sized one. Most come with an adapter so that they can be read by a computer or a camera. You can't cut a full-sized card down to fit into your phone and jimmy-rig the contact pins. I've tried. And tried.

SD cards in the Moto G

SDXC cards

Motorola says the Moto G 2015 only supports cards up to 32GB in size. At a glance, now that you know all there is to know about SD card standards and form factors, you would think that means they only support the SDHC standard. But that's not the case.

Both the 64GB and 128GB SDXC cards in the picture above work fine in the Moto G, and they're both formatted as SDXC. Phil also uses a 128GB SDXC-formatted card in his Moto G 2015. Alex, however, has a 64GB card that won't work in the Moto G, even though it works fine elsewhere. Yes, this is all anecdotal evidence, but it's all we have.

What we know is that Motorola says only 32GB cards are supported. Phil was told that once cards get over 32GB in size, there may be some "wonkiness" — Alex's experience reflects this. Officially, Motorola told me that cards up to 32GB are supported, just like it says on the spec sheet.

We have a few ideas what may be happening (my bet is that SDXC cards are supported, but performance while indexing anything larger that 32GB will suffer) but all we can really go with is what Motorola wants to officially tell us.

Media storage options on the Moto G 2015

Using the SD card on your Moto G is simple. To make the SD card the default storage location for all the pictures and video you take, open the camera app, slide to the right to get to the settings wheel, and tap the little wee SD card icon. From now on, all your camera photos and videos will be written to the SD card.

To move other media, like pictures or video you have taken before you made the change above, or downloaded music files, you'll need to dive into the device settings. Open them, tap the "storage" list item, and scroll down until you see "Move media." Give it a tap, and choose which types of files to move.

Easy-peasy.

My brain is tired. What card should I buy for my new Moto G?

Sd card storage

The most important question, and the easiest to answer.

Buy a card that is big enough to do what you need, that has the fastest read/write speed available.

Ideally, you'll buy a high-speed 32GB microSD card. This way, you're using an "officially" supported size, but that's not the only reason to skip filling a card with GB after GB of files. The other, and more important reason, is system performance.

We didn't talk speed on purpose — buy the fastest card you can buy, every time. This means UHS rated read-write speeds. The extra money is well spent here. Pictures and video will write to the SD card faster and smoother, and when Android M lets us do a little more with the card, those things will benefit from the higher speeds. The speed of the card itself is (usually) clearly marked on the front. Speeds are measured in "classes" with class 2 being the slowest and UHS 3 being the fastest. Avoid class 2, class 4, and class 6 cards every time. Class 10 cards have decent read and write speeds, but UHS (Ultra High Speed) cards are what you really want — especially if you shoot a lot of video in HD or 4K format. But the biggest reason to want a high-speed card of a moderate size is how file indexing works, and the fact that the Moto G has mid-range internals.

Periodically, your phone will need to index — look at file headers and file information to see just what's there — all the files on the SD card. This is easy to see in action, just eject and re-insert your SD card. If you have a 200GB card, filled with files, this is going to take quite a while on the Moto G. Your whole phone will be a bit sluggish while it's doing it, too. Instead of putting everything on your SD card, try to get into the routine of using cloud storage (or a computer backup, or both) for the things you don't need right now. The fewer the number of files on your SD card, the faster MediaScanner (the service that does the indexing) will finish.

Using a card bigger than 32GB won't necessarily break anything. As long as your Moto G can see your card (Hi, Alex!) it should work. You'll just have a bit longer wait when indexing or searching through files stored on the card if you have a big card filled with files.

I use these cards in all of my devices (both Android phones and other stuff like cameras and my now-deceased Walkman) including my Moto G 2015. Of course, they are above Motorola's official 32GB limit, so YMMV.

  • I am sticking with 32gb on mine. I have it almost filled with my music collection. I have tried larger than officially supported cards on other phones and they always seem to make the phone slow down.
  • "It should works. It might not work, but it SHOULD work." Take your chance on microSD roulette if you really need a larger card.
  • I wonder how far along we would be if Google hadn't tried to kill them. You can thank Samsung for keeping them afloat. Now it is the exact opposite and I have a sad about it I suppose. S-Pen goes *** Click ***
  • I'm no Samsung fanboy but your absolutely right Samsung really had that sector down especially through the kitkat Era where Google screwed it up Samsung kept their existing implementation and they did it right I stored a bunch of movies on my 64gb card on my s5 and they made it so easy with their file Explorer app. IMO Posted From my Nexus 6/Nexus 7 2013/Surface pro 3
  • Exactly Posted via the Android Central App
  • Yep, I humbly agree with you. Back in the day, when Google, HTC and LG plus some others didn't care about the SD card (and tried to kill it), Samsung still kept it and even promoted it. Now, it's the other way around. Posted from the LG G4 "Spigen + Anime" Edition. Wait, what?
  • It's an absolute nightmare to back things up in their entirety without the cards, the one pushed by Google and others is putting it on the cloud, no thanks. I'm glad the other three are keeping it alive even if Samsung lost it.
  • I don't like SD cards, and I have no problem with Google trying to kill them, but they needed to double down on it by offering extra large storage options on the Nexus line. The 16GB N4 worked fine for me personally, but if they'd opted to go with 16/32GB variants of the N4 and 32/64GB versions of the N5, that could've been the first nail in expandable storage's coffin, and I would've been more than happy with that. Posted via the Android Central App
  • ... And you just explained one of the reasons for my deep hatred for the N4. We should be at 64/128 now but all the Nexus enthusiasts went with 8gb is plenty. I railed against it to the point of getting a banhammer. The glass too. A few other things as well. The storage really got me though S-Pen goes *** Click ***
  • Just bought a 64gb microSDXC sdcard, had no trouble formatting it to ext4 from twrp......
  • I have a 64GB SDXC card in my MotoG and it recognized and formatted for me with no issues at all. I came from a 16GB Nexus4 and never had any storage issues there so it's a big jump to this 80GB capacity. http://www.amazon.com/gp/product/B00X1404E4?psc=1&redirect=true&ref_=oh_...
  • 64 and 128 GB cards are supported. exFAT is not. The FAT32 file aystem supports up to 2TB. Moto G supports FAT32 and will reformat any card that FAT32 can support. Posted via the Android Central App
  • I'm using exFAT formatted cards in mine right now.

  • Um. Joke. Posted via the Android Central App
  • he wasn't replying to you
  • Um. Probably right. These comment replies are going in the wrong places for me anyway, I can't keep track. Posted via the Android Central App
  • I suppose that Motorola simply refused to pay the license to the exFAT filesystem that is associated to the SDXC standard. Since their SD licensing is restricted to SDHC, they can only claim compatibility with cards of up to 32Gb. Notice, however, that the advise to buy the fastest card might imply that you are overpaying if your device does not support the UHS Phase I bus. A cheaper Class 10 card would give you the fastest speed possible in your device while you save the higher cost of a U1 or U3 card.
  • Do the different formats differentiate in speed? That was my main reason for getting away from any phone that was stuck using memory cards as their main source of storage. My note 4 would choke and lock or I'd wait for more than a minute for it to catch up if I had to scroll down 300 pictures deep on my 64gb card which had over 10k pics. Forget about getting to the last pic on the card it would never make it. Posted via the Android Central App
  • MiniSD to Full SD adapters do exist. I had one of the old Verizon XV6700s that took a mini sd card, and I had an adapter to put it in a full sd slot. A quick search of amazon also confirms this. If it does indeed have extra pins, I'm not sure how the adapter is wired, but I would assume that it functions fine without them.
  • UHS -3 does not exist. UHS -2 does exist, but for increased speeds, it requires an extra row of pins.
  • To be exact, UHS Speed Class with marks U1 and U3 run on SD Bus Modes UHS-I or UHS-II. See below: https://www.sdcard.org/consumers/speed/ Is this what you intended to say?
  • basically, yes
  • The article says to use the fastest SD card you can obtain, so shouldn't you be using the SanDisk Extreme card instead of the SanDisk Ultra card? Or is the difference in the performance negligible? Posted via the Android Central App
  • Got a G 3rd generation to replace an S4. Faster in use for everything but gaming. Even though it's a lower res screen it's much brighter. I can use it in full sun comfortably which was impossible with the S4. Camera is fast and excellent. Big improvement all around.
  • I´ve got two 64 gb cards right here that are not being used--a samsung "evo" and a Lexar "high speed" micro sdxc. Which would be better with the moto G? This 32 gb limitation makes me just want to wait for the Moto x.
  • Got an evo that works just fine in my note 4. Posted via the Android Central App
  • As long as you don't have much stored on it. Even the Samsung pro won't provide satisfactory results when it comes to large amounts of pic files....its limited by the note 4s ability to read and write data... and I don't see the phone this article is about handling it much better since it's a budget phone. Posted via the Android Central App
  • So I'm sure 64gb could be fine, but 32gb is enough for a Moto G 2/16.
    Not putting it down, I may get one, but I think you would be less inclined to want to fill it than like, say, a Note 4/5 , S6 x, G4, N6 etc.; from it's more limited capabilities and with what is now a bog standard but decent 720p screen.
  • Oops, forgot one! The Reduced-Size SD card known as RS-MMC. The "adapter" was a blank half-card that clipped onto the back to make it full length. I have one sitting in front of me now. These were used in feature phones like my Siemens S66, which amazingly also handled 32Gb back in 2004.
  • Quick question: Does the Moto G support SD card encryption, and if so, how much does it impact speed?
  • Oh goodness, don't do that! .... OK, before the security-concious tear me apart for that one, let me clarify... When even the Nexus 6 slows down considerably using device encryption (aka, encryption on the internal storage), the poor Moto G will have a heck of a time dealing with encryption on the SD card. Logic would indicate performance would be rather dismal. Posted via my Golden Zenfone 2
  • Yes, logic would dictate dismal performance, but I was looking for actual comparisons. My laptop is encrypted as required by my job, and it struggles along about 40% slower than before. I've avoided it on high end smart phones, so I certainly would not consider it on a mid tier phone like the Moto G.
  • Honestly, I still think that the SD card will live on. Even as others claim that cloud storage is the future, there's still a purpose for the humble SD card.
  • maybe in cameras., Samsung is slowly deviating from the SD card feature. Posted via the Android Central App
  • There's still quite a number of current flagships that still have one. Like the Moto X Pure, LG G4, Sony XPERIA Z3+, HTC One M9, and some. Posted from a metal Nexus
  • There are plenty who won't use cloud storage, myself included, because of the unscrupulous behavior of companies with your data, Google for instance rifles through your files and deletes anything they find disagreeable.
  • SD Cards are much slower and much less secure than Internal Storage. slow, big security holes. don't need them, don't want them. Google knows best. Nexus 5 + AT&T GoPhone
  • Google doesn't know what I want Posted From my Nexus 6/Nexus 7 2013/Surface pro 3
  • Granted, SD is slower than internal, which is why running your apps and databases from the card is not optimal. But for media content, there is no performance hit at all. My phone is just as fast in every day tasks and gaming with or without the card. In terms of security, you can hack the phone and both internal and external memory are fully accessible. I would be more concerned about someone capturing my Bluetooth streams and re-compiling my conversations and files, just like we did in my department at work a couple months ago. That would pose bigger problem than someone listening to my music ;)
  • I do not care about SD cards anymore as they are not efficient when it comes to long term storage. My SD card erased my photos which account to 2GB when I moved it to my newly bought Note 4 and it was original. I had it for couple of months. Posted.
  • Will a 64GB SDXC card work in my Idol 3? Posted via the Android Central App
  • This article was an excellent read.
  • Great article. I didn't even know about UHS cards. I always thought class 10 speed was the fastest and used that in an old video camera. Here's hoping the 64 GB I ordered will work in moto g 2015. I'm glad that the Moto X Pure will support up to 128GB officially. Curious about the constant mention of Android M doing more with micro SD cards when it comes out. Why would they even do that if nexus devices don't have them. Although you can save Google music and Google movies to SD card. Probably wishful thinking on my part that the the Nexus 7 might have a micro SD card slot. Posted via the Android Central App
  • After the Samsung debacle, I applaud Moto's decision to fully support SD cards in this release generation. I can understand the 32GB limitation on the G since it is meant to be a mid-range phone. I don't buy any of the arguments against SD cards in phones - they are much faster than some of the naysayers make out and sometimes it is simply the phone's implementation that slows them down. If they are good enough for DSLRs then they are good enough for phones (as long as you buy decent ones). They are a still massively faster than your average 4G connection. Try streaming that 4K video (that you recorded and had to upload due to lack of space) and see how long your data allowance lasts. Quite simply, we have no other option for mass storage even in 2015. I had 16GB internal memory in my (mid-ranged) phone from 2010 and with the explosion in photo, video & app sizes it is ridiculous that we have only just moved to 32GB for top line models. 64GB and 128GB options are limited in their availability and are massively overpriced. An SD card also gives your phone a certain upgradability - you can buy your phone then if you need more space just buy a bigger card. Buy the wrong size phone with no SD and its gonna cost you big time. I would actually be happy if the SD cards were formatted in a different format than exFAT just so there's none of this MS tax bs. Even if that made it a little less convenient for us, if it meant a faster, cheaper product I would be all for it.
  • Excellent article a lot of useful info in here. Posted via the Android Central App
  • Will the 2GB/16GB Moto G (2015) come to Europe?
    http://www.techtastic.nl/motorola-moto-g-4g-2015/
  • Great article.
  • Just got my new Moto G today (16gb version...). Tried to move my microSD card from my Note 2 into the Moto G. The Moto G will not even read my card, saying it is blank. Kingston 64gb microSD, class 10. SDXC. About 21 gb free out of 58.4 and phone says its blank. exFAT. I'm going to copy card to pc desktop and let Moto G format the card and see what that does. Posted via the Android Central App
  • OK, just reformatted the card in the Moto G. It is now FAT32 file system and the phone reads it as a 64gb microSD card. Shows 58gb and change available on a newly formatted card. Reloading my music on it now... Posted via the Android Central App
  • i got my Moto G on Tuesday , and loaded my 64GB sd card that i had used on my xperia z1 compact; i was disappointed when i got the notification that it could not be read. After a few tries with the same result every time, I loaded my 32 GB sd card that was on my samsung note 8; it worked just fine. Today after I backed up my data on the 64GB card to my PC, I loaded the 64gb card on the Moto G again, and after i got the notification that it wasnt readable I clicked on it to format the card; the phone can read it now! all I have to do now is copy my music to it (about 29 gbs worth) and I'll be ready to roll.
  • Does the Moto G support UHS-I and/or UHS-II?
  • Little late but yes, it does support UHS-I. I have a SanDisk Extreme 32GB Class 10 U3 (UHS-I) in my Moto G 2015. Not sure about UHS-II but according to Wikipedia it should support that too. https://en.wikipedia.org/wiki/Secure_Digital#Compatibility
  • I bought a 32GB Kingston card (supposed to reach 90MB/s in read ops and 80 MB/s in write ops) and it does not work with my Moto G 3rd version (2015): the card randomly gets unmounted and the phone blames me for doing that. Sincerely, this praised phone is sub-par.
  • I can confirm that behavior. Used a Brand new Kingston 32GB U3 AS infernal memory and it got unmounted after one day.
  • I bought a 64GB card which my moto g didn't recognise. I nearly accepted that it wouldn't work but then read this other article and used the utility to format the card on my pc. now it works! article:

  • Why can't SDXC just be implemented on on all devices with expandable storage? I realizes that the licensing cost would possibly raise the price a bit but surely a SD/SDHC/SDXC license couldn't cost that more than a SD/SDHC license?
  • To get people to buy more expensive phones? I guess? Manufacturers already make phones in a hierarchy (on top the most expensive phones with the best hardware and features, on the bottom the cheapest ones with the most limitations). It gets people to decide if they want to spend more money on (let's say) a Moto X 2014 with 16GB/no microSD slot and better specs or on a Moto G 2nd Gen with 8GB (potentially 40GB overall) and lower specs. They need to differentiate their line-up and put specs on them which represent the tier. At least that's what I think, so don't take it for granted ;)
  • You were doing so well until you stated that Moto G 2nd / Moto G 3rd Gen. with internal 8GB (User Memory about 4GB) ROM + 32GB (User Memory about 28GB) ROM MicroSDHC Card = 40GB (User = about 32GB) ROM, using Marshmallow 6.0+ (latest Android Operating System, that replaces Lollipop 5.1.1) had more ROM than Moto X 2014 (more expensive phone) 16GB (User Memory about 12GB) internal ROM. Motorola has placed 128GB GB MicroSDXC drives into; Moto X 2015 and Moto Style 2015 UK versions, because not having 128GB MicroSDXC drive with Marshmallow 6.0+ is stupid. Marshmallow 6.0+ should be further improved to also increase the ROM further, using for example SanDisk Ultra 128GB USB 3.0 OTG, and use part of the memory to at least significantly increase the speed of existing Android Smartphones.
  • Hi, thanks for this great and friendly post. One question, where you able to tell to WhatsApp or Spotify to store their contents on the MicroSD too or this is not possible? Maybe Apps can be moved to the MicroSD entirely? Sorry if this sounds too stupid I am an iPhone user...Thanks for your help!
  • I just bought a Moto G 3rd and a pack of 5 Patriot 32Gb micro SDHCs class 10 / UHS 1. I put one in the Moto G, and it identified it as a Lexar, and moreover said performance would suffer if I used such a slow device! OoooK. The chips look exactly like what I thought I bought with a class 10 and U1 logo, and the Patriot logo. I looked at my storage settings, and it's identified as a Lexar there. I've decided the Moto G misidentified it. I did put one of these chips on a computer, and timed moving files. It seems normal for my computer. Has anyone else seen this?
  • I'm aware that this article is quite old now but I just recently switched back to Android from WP. So I might not get an answer.
    I was wondering what uproach was made on the testing? Did you format the microSD cards before putting them in your Moto G's? Did you put them in and let Android do the formatting? Were all tested Moto G's on the same version of Android and/or firmware version? Did you insert the microSD cards while the phone was on or off, and did you restart the phone after the microSD cards were inserted? You didn't really mention that in the article. Also: has anything changed regarding the support of microSD cards with Marshmallow? (besides the "portable" and "internal" storage thing)
  • The cards came formatted FAT. I turned the phone off, then inserted the card. When it came up, it did the formatting. It gave me the option to use it as internal storage or portable. I picked internal (integrated?). The phone's been off and on several times. When I go to Storage and USB in settings, it still says Lexar SD. I really think there's some ID on the chip and a table on the phone to match it that simply has an error. It seems to work fine.
  • Good questions. I just upgraded wife's moto g 2014 to A6 last night. Her 32 GB card is nearly full due to pictures and videos so I need to do some backup on that. But plan to try 128gb class 10 set to internal setting later tonight. Hope it works. When set to internal the phone does the formatting and it becomes encrypted on SD card so you can't pop it out and put in PC to read it. Downside to that is more difficulty in upgrading cards and moving data from one card to another. 128gb card works great in moto e gen 2 with A5.1 but can't move enough of app space to card, so constant struggle with minimal 8gb internal.
  • Is anybody have an issue with their SD Card transfer from phone to mac since the Marshmallow update on Moto G 3 ? When plugged it shows nothing on the SD card section..?! Help
  • I am having an issue where my Moto G3 seems to lose track of the SD card. it works for a while. Then the next time I start the phone it can't find the thing, and of course all the apps are also missing. Can you help with this?
  • I can't help, but hoping someone else can... Same thing just happened to me. SD card (lexar 32G) just dropped out. Initially, app icons greyed out, then vanished after restarting. Card not mounting, not found by file explorer, SD card settings have "checking card..."
  • does not relate in any way to my MOTO G3, no app manager . no move media . G3 is lousy wont store in sd card
  • Does anyone have any suggestions or recommendations for how to transfer from one SD card (A 16GB class 4) which isn't performing very well, especially with the camera app, to a newer 32GB class 10/UHS-1 card which I hope will alleviate the performance issues? As I've already configured the existing card as an extension of the internal storage, I'm not sure how to go about moving the existing data from that card to a backup (on my PC, presumably) and then returning it to the device once I've swapped over to the newer, faster, bigger card.
  • I bougt my MOTO G3 TURBO and inserted my micro SD from my old MOTO G2, it was an Kingston 32 GB Micro SD Class 10/ HC I U1 it worked fine for a long time, but, after one year of use and a few android updates, my MOTO G3 TURBO became laggy, specifically with facebook, messenger and sharing options, so i decided to apply format factory, everything seemed to be ok. When the format factory finished my devide showed a message "sd card couldn't be compatible" i ignored the message since i have beeng using it for a year, so i atacched it as internal storage, and the process took long time. But when it was time to install facebook or messenger the download process seemed to be impossible, sometimes the download began and took long loooooong time "downloadng" suddenly the download failed with no advice, and after several attempts to install facebook or messenger looked to be installed, but the apps used to disappear, SO i tried format factory 2 or 3 times more, with the same result. By accident at 4th attempt i didn´t inserted SD card ind reinstalled everything, suddendly i had installed facebook and messenger as usual, with no problems, then i realized it was my SD card was the problem. So, i was confused, Class 10 was the fastest standard i knew, and after a research I found that new standard were aviable UHS-I and UHS-II with a variant U1 and U3, so i looked for a reliable option and dediced to buy Lexar High-Performance MicroSDHC 633x 32GB UHS-I/U3 (Up to 95MB/s Read) w/USB 3.0 Reader Flash Memory Card LSDMI32GBBNL633R
    I received itand now my MOTO G3 is working fine again.
