This thing solves all of RAID’s problems, while maintain all the redundancy. If it had built-in NAS, instead of the add-on module that works by disabling local access, I’d buy one today. Even with that caveat, Drobo is how external disc storage should work.

Have trouble remembering which RAID does which? I sure do! I mean, really a numeric naming system doesn’t suggest that much information about which type does what?

Fortunately, iBeast provides this handy RAID Calculator.

Redhat’s online documentation provides a good refresher as well.
