Best microSD Expansion Cards for Surface Book 2, Book 3 in 2022

Microsoft's Surface Book family all have full-size SDXC readers, which is great if you're taking photos from a DSLR or something, but many devices use microSD cards. Unfortunately, the Surface Books do not have a MicroSD slot. Still, it's worth getting an adapter to increase your device's capacity or make it easier to transfer data from other hardware. After picking up an adapter, you'll want to choose from these excellent microSD cards.

Samsung EVO Select 64GB (opens in new tab)


For $12, you can get this 64GB microSD card, which had read speeds of up to 100MB/s and write speeds of up to 60MB/s, with Class 10 and U3 compatibility, making it great for all types of content and a significant boost to your Surface Book 2's onboard storage.

If we were to make a suggestion

Though onboard storage may be enough for most people, the ability to quickly move media and files anywhere is incredibly convenient, which is why a quality microSD card makes all the difference. However, Surface Books lack a microSD slot. You'll need a microSD adapter to expand your storage. After that, the world is your oyster.

For value, it's hard to beat the Samsung EVO Select (opens in new tab) lineup, but if shear capacity is all you care about, then the SanDisk Extreme (opens in new tab) is what you want.

Adding a further 400GB to the Surface Book's internal capacity would allow you to manage content such as photography and 4K media files should you want to do some editing on the go. There are other benefits like being able to move data between devices quickly, and because it's SanDisk, you'll be able to rely on high performance with a 10-year warranty.
