Get a better RAID controller, from the looks of things that looks to
be one of those cheap shit software RAID controllers that depend on
the drivers to do most of the work. Supermicro last I checked at
least didn't have any boards that had good RAID controllers on
them, even their zero channel controllers while I'm sure are probably
higher grade then the on board controller still look poor by comparison.

I had a similar situation on a bunch of HP DL320s a couple of years
ago, they came with Adaptec hardware "RAID" as well, we found out
pretty quick that the drives were corrupting themselves underneath
the controller and even doing a "full check" on the drives via the
controller said they were good.

Software RAID ended up being what we went with.

Cheap hardware raid is worse than software raid.
