Best SD Cards for Chromebooks in 2018

by John_A


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. It’s not exactly the same because Chrome’s security model treats storage you can remove differently than storage you can’t, but an SD card slot means limitless storage space for photos, video, documents or anything else that you need to keep somewhere.

Whether you use a full-size SD card, a microSD card or a half-height SD card depends on your particular model of Chromebook. Or maybe, you can’t use a SD card because you don’t have a slot for one — we have you covered, too.

  • Half-height SD cards

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 SDXC


If your Chromebook has a full-sized SD card slot, this is a no-brainer. The SanDisk Extreme Pro SD card is the best SD card you can buy.

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. You’ll also find it available in models featuring 8GB (but don’t buy anything smaller than the 32GB version or you’ll wish you hadn’t) of space up to a whopping 512GB version.

Like all full-sized SD cards, the SanDisk 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 is the one to buy. Pricing starts around $20 for the 32GB model.

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 to make things work with a full-sized slot.

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 100MB/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. The 200GB model comes in around $60. If that’s more than you want to spend, prices start at just $13 for smaller capacities. you can even find a 400GB version for about $190 if you’re that kind of baller.

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.

These EVO cards are fast enough for most everyone, and $40 gets you 128GB of storage from Samsung.

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


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).

These aren’t cheap — the 64GB model is around $50, but 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


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 snag on things. Best of all, they’re only $9.

An alternative

SanDisk Ultra Fit 128GB USB 3.0 Flash Drive (for older USB-A ports)


Maybe you don’t want to use an SD card at all but still want to expand your storage or you don’t have a SD card slot on your Chromebook. 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. Its low price — $30 for 128GB — fits snugly against your heart, too.

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!

SanDisk Ultra USB Type-C 128GB Flash Drive


While these don’t fit flush to the side like the USB Type A flash drives above, they are fast and reliable removable storage for your Chromebook if it only has newer USB-C ports.

The 128GB model sells for around $40, and it offers USB 3.1 compliance with read speeds of up to 150MB. It’s fast, and SanDisk is known to build reliable storage. Eventually, we’ll see “shorty” USB-C flash drives that don’t like to protrude so much, but until then these flash drives are a great way to expand your storage.
