Well after launch, Samsung started offering increased storage options for the Galaxy S9 and S9+, giving buyers the choice of 128 or 256GB in addition to the default 64GB it sold for several weeks after launch. If you haven't yet bought a Galaxy S9 or S9+, it's absolutely worth exploring which storage option is right for you. Here's what you need to consider.

Internal storage is not the same as SD card storage
You may be saying to yourself, "why would I buy more internal storage when I have an SD card slot?" Great question, and here's the answer: your microSD card is not treated the same as internal storage. This is because Samsung still uses SD cards as removable storage rather than adoptable storage, meaning the card is treated as a separate volume. That has all sorts of benefits, like allowing you to remove the card without disrupting the phone's operation, but also has downsides.
SD cards are great for mass storage of data, but not necessarily for data you need to access quickly and reliably. You can store pictures, videos, music and movies on your SD card, but things like apps and sensitive data can only be placed on internal storage. Large chunks of data can't span across internal and external storage, either — they have to be stored entirely on one or the other.
Having an SD card slot in your Galaxy S9 or S9+ gives you lots of options for upgrading your storage after purchase, but isn't a one-to-one replacement for buying more storage from the start.
Where you buy the phone matters
Higher storage options for the Galaxy S9 and S9+ are only available online, from Samsung, as unlocked models. That means you won't be able to head to Amazon (opens in new tab), Best Buy (opens in new tab) or your carrier and get a GS9 with 256GB of storage — annoying, but it's the reality we're dealing with.
Buying an unlocked phone from Samsung in itself isn't a problem at all — in fact it's preferable in almost every way. The unlocked phones from Samsung work on all major U.S. carriers, but are free from the bloatware and annoying software changes that you'll so often find on carrier models.
Going this route is only a problem if you're trying to take advantage of carrier incentives on your Galaxy S9 or S9+ purchase. Having more storage is awesome, but if Verizon is offering a BOGO deal (opens in new tab) or Sprint has a big discount on its lease program, those savings may outweigh the benefit of the extra storage for you.
Pick a storage size
Alright, so you've determined that you're okay buying the phone from Samsung, and you know that an SD card is not a direct replacement for internal storage — now, which storage size should you buy? The best way to start off here is to say "buy as much as you want to pay for." That is, if you have the extra $100 and plan to use your Galaxy S9 or S9+ for a long time, buy the 256GB model. You'll never regret having more storage, especially if $100 (or about $4 more per month when financed) isn't that big of a deal to you at the start.
On the other hand, most people who don't know how much storage they'll need will be completely happy paying just $50 more to have the peace of mind that 128GB of storage brings. You probably won't ever be pushing up against the 64GB barrier on the base model, but having 64GB more room beyond that is simply nice to have and doesn't cost that much extra. And you're far less likely to hit any sort of nagging "storage full" message when you go to install a hot new game or record a bunch of 4K video a year from now.
And finally, if you've never had a phone with over 32GB of storage and haven't been close to filling up those smaller storage sizes, you're going to be fine just getting the default 64GB model and saving some money. Put some of it toward a good case or some other top-notch accessories instead.

If you're thinking about buying that 256GB model, think about doing it sooner rather than later — Samsung has a $20 discount on the top storage options of both the Galaxy S9 and S9+ until May 17. After that, the prices will be $839 and $959, respectively.

The problem with internal storage is you have to use MTP to copy stuff over and MTP is totally crap on it's best days... There are down sides to using an SD card, but at least you don't have to put up with MTP.
How often you need to use MTP?
I only ever need to move large amounts of data when I get a new phone and the last time I moved an SD card it corrupted in the new phone.
I brought 128gb version S9+ here in India...Very happy coral blue color
Nice! The Coral Blue is the best color imo:)

Not entirely true - You lose support for certain features and services such as VoWiFi and VoLTE provided by the wireless service providers too. If you use WiFi calling for example you won't be able to with an unlocked phone.... So there's that also.
That is not entirely true. I have unlocked S9 on T-Mobile and Wi-Fi calling is working just fine. VoLTE is a different story.
Guess it varies depending on carrier... I know you can't with At&t or Verizon.
Get the largest amount of storage you can afford. If you put photos/videos/music/movies on an SD card, you should be able to make 64GB of internal storage last a long time. On my OnePlus 3T, with 128GB of storage, I'm using 24GB. And I don't even have the option to store things on an SD card.
If Samsung had a 512GB Version, that Would be the First and Only Choice, but since at the Current time the Largest Capacity is the 256GB Version, then it would be that one.
This question is like, which side of my nose should I pick? This phone supports SD cards, so who cares? Buy the 64GB. If u need more, stick a memory card in there for much less!!
Isn't it also true that unlocked phones are a lot slower getting updates, as if they don't come slow enough already?
Not if it's the Essential Phone ;-)
Good article for first time users. Well for a start when you buy the phone you should know what you need and things will be easier like it is mentioned here https://gizz9.blogspot.com/
I am still completely fine with 32gb internal storage as long as I can set the camera to save to SD card. I do not play games on my phone though.
I also wanted to inform everyone that Samsung is at it again with No updates as promised.. My Unlocked SM-G960U1 is STILL on Feb1 Security updates... That is a deal breaker for me..
