It’s called the “32 GB Microsoft Surface RT”. Microsoft:
Surface with Windows RT comes with either 32 GB or 64 GB of internal storage space (hard disk space). However, not all of this space is available for your music, photos, videos, and other content.
Here’s how much hard disk space you have available out of the box:
The 32 GB version has approximately 16 GB free hard disk space.
The 64 GB version has approximately 46 GB free hard disk space.
The Windows recovery tools take up around 5 GB of space. For comparison, the hidden OS X recovery disk partition is about 1 GB, and iOS’ recovery options are built into the approximately 1 GB OS package. Why can’t Windows RT use internet recovery options? That’s a lot of space to take up with tools that the user should rarely have to use.
