When you setup the RAID5 array, what stripe size did you use ? I found
problems with anything other than the default 64K. What BIOS rev are you
using? The only RAID 5 setup I use is on a 7810. 3dm2 shows
Model 7810
Serial Number F11402A2120284
Firmware FE7X 1.05.00.056
BIOS BE7X 1.08.00.046
Monitor ME7X 1.01.00.038
It stores pgp encrypted files that we check once a week to make sure they
are OK and I have yet to find any issues.
