Expanding your Chromebook's storage.

If you want to expand your Chromebook's storage, you can use an SD or microSD card and boom, you've got more space.

Whether you use a full-size SD card, a microSD card or a half-height SD card depends on your particular model of Chromebook.

Updated, April 2017: This post has been updated with the latest recommendations.

Full-size SD cards

Full-size SD cards are the largest SD cards in terms of physical size. Whether or not your Chromebook will fit a full-size SD card depends on the model and manufacturer.

Even then, a full-sized SD card may stick out of the SD card slot on your Chromebook and if this is the case, we don't recommend that you use a full-sized SD card in your Chromebook all the time, since it could catch on something. Instead, insert it when you need to transfer files over or access files you've stored on it previously, then remove it again.

SanDisk Extreme Pro 512GB SDXC

SanDisk Extreme Pro 512 SDXC

The highly-rated SanDisk Extreme Pro SD card is fast and has a large capacity, so it makes a good choice to expand the storage of your Chromebook.

It has data transfer speeds of up to 95MB/s, so you can transfer those Blu-ray movies you've got sitting on your Chromebook's hard drive without a problem. Even games with gigabytes of data can be moved over with ease.

Additionally, this SD card features write protection, which prevents you from accidentally erasing or overwriting your important files. No more worrying about accidentally erasing those old family pictures.

If you're looking for a fast, reliable SD card, this may be the one for you.

MicroSD cards

MicroSD cards are much smaller in physical size than their larger SD card cousins — about as large as a fingernail whereas SD cards are about the size of a postage stamp.

Their smaller size doesn't mean that they have smaller capacities than their larger brethren, however; they simply have a smaller form factor, and that means they're typically used in smaller devices, such as smartphones and tablets.

For the most part, if your Chromebook can fit an SD card, it'll take a microSD card. You'd just need an adapter, such as the Raspberry PI Shortening MicroSD Adapter.

SanDisk Ultra 200GB microSDXC

SanDisk Ultra 200GB microSDXC

The SanDisk Ultra 200GB microSD card is about as fast as they come, and with a 200GB capacity, it provides a lot of space for your files.

Transferring large files won't be a problem with its rated 90MB/s transfer rate and with all of that space available, it can hold up to 20 hours of HD video. That's right, 20 hours.

If you're looking for an expandable storage option for your Chromebook that's fast and has a large capacity, check out the SanDisk Ultra 200GB microSD card.

Samsung EVO Plus 128GB microSDXC

Samsung EVO Plus 128GB microSDXC

Slightly slower than the SanDisk Ultra microSD card, Samsung's EVO Plus 128GB is still fast enough for most uses and is correspondingly cheaper too.

While it doesn't have as large a capacity as the SanDisk Ultra 200GB, the Samsung EVO Plus may have enough to suit your needs if you are looking for a bargain. Though it's a little slower, you won't notice much of a difference when transferring files or media.

If you want a fast microSD card, but you want to save a buck, choose this one.

Half-height SD cards

Half-height SD cards, as the name implies, are SD cards that have a shorter form factor. They're a great alternative if regular-height SD cards protrude from your Chromebook's SD card slot and microSD cards aren't compatible.

Transcend JetDrive Lite 330

Transcend JetDrive Lite 330

The Transcend JetDrive Lite 330 comes in three capacities: 64GB, 128GB, and 256GB.

With a maximum rated read speed of up to 95MB/s and write speeds of up to 60MB/s, this half-height card is fast enough for downloading large files, and with its three capacity options, you can choose just the amount you need (and the price, too).

If you don't want to or can't use a microSD card, the Transcend JetDrive may be the card for you.

Shortening microSD adapter

microSD adapter half height

If you have a fast microSD-card or want to buy a new one in your Chromebook, you can get a half-height adapter to keep things from hanging out of the side too far. Originally designed for use in a Raspberry Pi, these adapters from Adafruit work exactly the same as any high-quality full-sized adapter. There's just less hanging out to snap on things.

An alternative

SanDisk Ultra Fit 128GB USB 3.0 Flash Drive

Maybe you don't want to use an SD card at all but still want to expand your storage. The SanDisk Ultra Fit USB Flash Drive offers up to 128GB capacity and its low profile fits snugly against your Chromebook when it's inserted.

Read speeds up to 150MB/s mean it's ultra-fast and the design means you can leave it inserted so it's always ready every time you boot up.

These are USB A (bigger, older style socket) drives, so make sure you have the right USB ports!
