What's the best microSD memory card for Surface Book? Here are our top picks.
Updated on February 7, 2017: We kept our list of recommendations as is but made it clearer which options are best for transfer speeds and users on a budget.
Microsoft's sleek and powerful Surface Book lets you expand its storage by using an SD card. However, standard-sized SD cards will stick out a bit, which can be an issue if you like to keep your SD card in your device most of the time.
Our intrepid Windows Central community members discovered a workaround for the problem, and we have some suggestions for microSD cards that'll work perfectly.
Your best option is to find a truncated microSD card adapter, which will mount flushly in your Surface Book so you have no protrusions or precious memory cards to get caught on clothing and other objects.
microSD card adapters
In order to use a microSD card and avoid the SD card-sticking-out issue, you'll need a microSD card adapter, one that's truncated so that you're not having the same problem.
BaseQi Ninja Stealth Drive
There is currently one microSD card adapter that's made for the Surface Book, and that's BaseQI's Ninja Stealth Drive. You can use any microSD card with this adapter, and it will fit flush with the body of your Surface Book.
Our Windows Central forum users have also had good luck with the MiniDrive, a short adapter that fits entirely inside the SD card slot and must be pulled out using the attached strap.
If you use this adapter with your Surface Book, you'll likely need something with which to grab the strap whenever you want to remove it.
The listing for this adapter says it's for Raspberry Pi, but at the end of the day, it's just a truncated microSD card adapter that's perfect for your Surface Book.
It doesn't sit perfectly flush with your Book, but it's far better than a regular full-size adapter and only protrudes slightly, so if you're relatively careful, you should have no problems.
For about $8, you really can't go wrong.
Once you've chosen an adapter, you'll need a microSD card to use with it. Here are a few handy choices:
- Budget-friendly: SanDisk Ultra 200GB microSD card
- Fastest transfer speeds: Lexar 128GB microSD card
- Best price-to-performance: Samsung EVO+ 128GB microSD card
SanDisk Ultra 200GB microSD card
With a transfer speed of up to 90MB/s, SanDisk's Ultra 200GB card is capable of lightning-fast performance, not only for transferring files back and forth but also for gaming applications.
Since it's rated a Class 10, the Ultra is able to store full HD video, and playback straight from the card is quick.
Another nice feature of this card is the free app that lets you automatically manage memory for the best performance.
Silicon Power 128GB microSD card
This microSD card from Silicon Power is another solid option for your storage and performance needs.
Like all of the microSD cards on this list, it can store and play back video in full HD. This is great for watching movies and other high-quality video on your Surface Book's 13.5-inch screen without having to upload it all.
In terms of speed, it isn't as fast as SanDisk's Ultra, but at 75MB/s, it's still quick. You can transfer files in seconds and play those games without worrying about a performance bottleneck.
Samsung EVO+ 128GB microSD card
Faster than Samsung's regular EVO line, the EVO+ has a write speed of up to 20MB/s and a read speed of up to 80MB/s, and it is perfect for expanding your Surface Book's storage. It's advertised as waterproof and even capable of withstanding up to three days in corrosive seawater, so no matter what aquatic tragedy befalls your Surface Book, rest assured that the data in this microSD card will be safe.
As a U1 Class 10 microSD card, the EVO+ will have no trouble storing your full HD video and high-res photos, so it's perfect for presentations, documents and just about everything you'd store on a computer hard drive.
If you happen to have to suffer through Canadian winters, the EVO+ is also temperature-proof to -25 degrees Celsius.
Lexar 128GB microSD card
This microSD card from Lexar is the fastest one on our list, so if transfer rate is the deciding factor for you, this is the card to go with.
Like all of the other microSD cards we've covered, Lexar's offering is capable of storing and playing back video in full HD. But speed-wise, Lexar has all the others beat with a transfer rate of 95MB/s. If you're dealing with extra large files or want to watch movies straight from the card, this is the one for you.
Transcend 128GB microSD card
Transcend doesn't win the race in terms of file-transfer rate, but with solid user recommendations, it remains a decent way to expand the storage capabilities of your Surface Book.
While ultra high speed class-compliant, with a transfer rate of only 45MB/s, it is the slowest microSD card on this list.
However, it's still capable of storing and playing back HD video, though you'd probably want to transfer a movie to your Surface Book and watch it from there.
If you're just after additional storage space for your Surface Book and you're using it more for documents and not so much audio or video, you should look at Transcend.
