Is Surface Pro X SSD Upgradeable?

Unlike previous Surface devices, such as Surface Pro 6 and Surface Pro 7, the Surface Pro X SSD is upgradeable. Because the SSD is not soldered, just hidden behind the kickstand. According to Microsoft, the Surface Pro X SSD type is an M.2 2230 SSD, which is smaller than most M.2 SSDs. So It is not very easy to find one.

Microsoft also says the SSD is not user removable and should be replaced by a trained Microsoft technician. If you want to swap SSD yourself, don’t forget to prepare the right Torx screwdriver and the way to install Windows on the new SSD.

Why Upgrade Surface Pro X SSD?

Here are two main reasons why you need to upgrade Surface Pro X SSD. If you're not sure it's time to upgrade, take a look and then decide.

  • Get More Capacity. In amazon or eBay, most Surface Pro X comes with a 128GB or 256GB SSD. If you want more space, Surface Pro X 1TB SSD or 500GB SSD will be a great choice.
  • Improve SSD performance. The default SSD in Surface Pro X is, at best, a low-to-mid-rang performance. To yield +500MB/s sequential read and write speed, the best way is to upgrade SSD in Surface Pro X.
