Can you upgrade the storage in a Surface Book?

Updated May 29, 2017: We've refreshed this list to ensure you're still getting the cheapest and easiest way to expand your Surface Book's storage.

The Microsoft Surface Book is a very powerful laptop with a 2-in-1 design, a touch display with a unique aspect ratio, and a high price.

One of the best ways to lower the initial cost of a Surface Book is to dial back the hardware inside, namely the solid-state drive. 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 solid-state drive, 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 doesn't have upgradeable hardware.

Add Surface Book storage with a microSD card

The BaseQi microSD adapter

The Surface Book comes with an SD card slot on the side, but you don't want to use a regular SD card, 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 probably doesn't bode well for a thin piece of plastic that can be snapped off ‚ÄĒ or worse, break the SD card slot itself!

SanDisk Ultra 200GB

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

Add this to the $80 cost of a 200GB SanDisk SD card, and you're already saving money, considering Microsoft charges about $300 for an extra 256GB of storage built into the Surface Book. Yes, some of you will notice a difference in performance between your solid-state drive and a microSD card, but for many people, the price difference is worth it.
