Erm, I never mentioned the type of drives or setup. I've got one with 24
500GB SATA drives and another with 16 1TB SAS drives. And, yes, both use
RAID6. Short of a 3ware firmware issue on the first system (leading to
crashes, subsequent fscks, but no lost data and which is now fixed), both
are running smoothly.
