I just had a Seagate 1.5 TB fail on me, I had my /var and /usr mapped to it so I'm hosed. My setup had been working flawlessly and I really put it to the test compiling some monstrous stuff.
Now I'm looking for a RAID solution.Drobo
looked possible, but as I read the reviews on Amazon, there are too many complaints, some serious insofar as files are just missing without notice and Drobo simply reboots. Looks like Drobo is not a good candidate.
So the issue becomes do I find a SheevaPlug => USB => RAID solution, or can I do a RAID within my operating system, Gentoo, with mounted USB drives.
No answer yet, just thought I'd post my current thoughts.
