How to add storage to a Microsoft Surface Book 2 on the cheap

Can you upgrade the storage in a Surface Book 2?

Microsoft's Surface Book 2 is a very powerful laptop with a 2-in-1 design, a touch display available in two sizes, and a high price. One way to save a bit of money at checkout is to dial back the size of your solid-state drive (SSD). You can save hundreds of dollars by opting for a 256GB storage option rather than a 1TB option.

Even if you did opt for a big 1TB SSD, the reality of media today is that it will eventually fill up. In either case, you're probably wondering how to get a bigger drive when the Surface Book 2 doesn't have hardware that's easy to upgrade. Despite no longer being available from the Microsoft Store, this solution also works with the original Surface Book and Surface Book with Performance Base.

Add Surface Book 2 storage with a microSD card

The BaseQi microSD adapter

Note: This solution works with the 13.5-inch Surface Book 2 and the original Surface Book line. The 15-inch Surface Book 2 is awaiting an updated adapter that will sit flushly.

The Surface Book 2 comes with an SD card slot on the side, but you don't want to use a regular SD card all the time, as it doesn't sit flush with the device. This isn't a big deal when you're just quickly transferring files, but for a more permanent solution, you want something that doesn't stick out. The daily life of your Surface Book 2 probably doesn't bode well for a thin piece of plastic that can be snapped off — or worse, break the SD card slot itself.

What you need is a microSD adapter that fits into the SD-card slot and sits flush with the Surface Book 2. This option from BaseQi costs about $25 and allows for a nearly seamless fit.

SanDisk Ultra 200GB

Add this to the $75 cost of a 200GB SanDisk SD card, and you're already saving money, considering Microsoft charges about $500 for an extra 256GB of storage built into the Surface Book 2. Yes, some of you will notice a difference in performance between your SSD and a microSD card, but for many people, the price difference is worth it.

Executive editor Daniel Rubino already wrote a great piece about using a BaseQi microSD adapter with your original Surface Book that you can check out if you have more questions about this smart, cheap storage solution.
