Best answer: Having 64GB storage in your Surface Go actually equates to just 44GB of usable space following the installation of Windows 10 and associated files. If you plan on storing files locally, this might not be enough space. Luckily, you can add a microSD card to expand storage, and there is a 128GB Surface Go model available from Microsoft.
What is the 64GB Surface Go good for?
The 64GB Surface Go uses slower embedded MultiMediaCard (eMMC) storage and has 4GB of RAM, making it ideal for light computing tasks. This baseline model will serve you well as a secondary PC since it's able to handle word processing, web browsing, email, social media, videos, and even some light gaming.
What about the 128GB Surface Go?
The 128GB Surface Go model uses a faster solid-state drive (SSD) for its storage, and is likewise equipped with 8GB of RAM. Combined, this model is much better suited for life as your primary PC. It still has a microSD slot for additional storage, and it can certainly be used with cloud storage if you're still short.
The only downside here is that it costs $150 more than the 64GB Go, and if you're just buying it for the extra storage space — not everyone needs 8GB of RAM or cares about speedier data transfer — there are cheaper alternatives, like buying a microSD card.
Expand your Surface Go storage with a microSD card
The cheapest and most efficient way to add storage to your Surface Go is through the microSD card reader. In the past, SD cards could only be used as external storage for things like photos and videos, but Windows 10 lets you use them as standard storage.
You can install apps, save documents, and move files back and forth, just as if the microSD card was part of the Go's internal storage. Some built-in Windows 10 apps cannot be moved, and some developers can flag their apps as not compatible with SD storage, but for the most part, you should be OK.
Considering how cheap you can find SD storage, you can often double, triple, or even quadruple your Go's Storage for less than $30. You won't get quite the same transfer speeds as with the internal storage, but it's undoubtedly worth the price tradeoff.
Silicon Power 128GB microSD card
Cheap storage for your Surface Go.
Instead of paying $150 extra for the 128GB Surface Go configuration if you don't need the extra performance, why not add an extra 128GB for about $19? This microSD card reader from Silicon Power was a contender during in-house testing, and with it installed you'll have a total of 192GB at your disposal. Those are much better numbers.
