I have been running with my 2400A for a few months now in a RAID5 configuration with 4 Western Digital 80GB discs (special edition with 8MB cache) and it has worked very well. I haven't had any serious problems. The only problem I had, was one time the mirror got degraded because the RAID card said one disk had failed. I don't know what happened, but after a test of the disk with WDC's test program (which didn't reveal any errors) and a RAID rebuild everything was fine again. I'm running 5.1, but I ran 4.8 when I initially tested it and I haven't experienced any data corruption with either FreeBSD version. > (Those of you with 2400A's: what motherboard and hard drives are you usin= g?=20 I'm using an somewhat old Asus A7M (I think it's called that; it was their first Slot A motherboard) with a 600Mhz Atlon. As mentioned above 4 80GB WDC disks. > Those of you with other ATA RAID cards: what's reliable and bootable?) You can boot a RAID1 with the ata(4) software RAID, no need for a RAID controller.
