3Ware 6200 and filesystem errors

I thought I’d swap over to my 3Ware Escalade 6200 and run 40GBG x 2 in RAID 1, but it was not to be. After migrating all my files over from my Quantum Atlas 10K2 9.2 GB SCSI disk and my /home from my single 40GB ATA disk, I started experiencing filesystem errors rather immediately. First it was only on the XFS filesystem, but soon I started seeing input/output errors on files on my ext3 filesystems. After running a memtest86, I came up with no bad RAM. Spending more time swapping back to the original configuration without the 3Ware card, the system is stable again. I’ve had that 3Ware card for six months, but never tested it. I guess it was dead on arrival. At $20 for the card, it was worth the risk. I could run software RAID, but don’t really feel like it. I’d rather send the data once to the hardware RAID controller than twice on the bus to each ATA disk. Plus, I’d need to install an PCI ATA controller to obtain enough free ports to run a disk per port. Ah well. Perhaps I’ll buy a 36GB SCSI disk instead…
