It's not a NAS, but you could hook it up to a low-power device and share it. I've got one connected to my primary machine and love it. Super fast storage.

Side note: One of the m2 chips that I got from Amazon was an obvious fake that I might not have caught if I hadn't ordered four together and one obviously didn't match.
