Yeah, but. Specifically, but, did you actually read about their plan for data
integrity? They expect those storage things to fail left, right and center,
and use higher level software to replicate data safely on multiple nodes.
Not exactly the level of reliability you want if you only have a half-dozen of
those things, let alone less. It works, in part, because "designed to fail"
is really good at a large scale, but not so great at small scale.
