Surface Pro Storage Spaces Boot

Boot from Storage Spaces Virtual Disk in Windows 10

A couple of weeks ago I got my new Microsoft Surface Pro, I decided to go with the 1TB version to have enough space.

After the first minutes of setup I quickly wanted to run disk optimization, which for SSDs usually does quick trim operations. In my case this was running way longer then on my Surface Book, so I checked what was going on, and I realized that it was running Optimization on a Storage Spaces Virtual Disk, which is kind of strange.

I checked the disk configuration and really, my Surface Pro (2017) does have a Storage Spaces Virtual Disk which it boots from. The Storage Spaces Pool does include two physical 512GB NVMe drives with one Virtual Disk on top configured as simple (striped) volume. Right now I don’t know how they did it, but it seems now possible to boot Windows from a Storage Spaces Virtual Disk with the Windows 10 Creators Update or some Surface team magic. Then when Storage Spaces was introduced with Windows 8, boot from Storage Spaces was not possible.
