You generally don't want database log files on a RAID5 array. Additionally, most cheaper RAID cards (i.e., anything that costs less than several hundred dollars) don't have good RAID5 performance. (Some of them are downright awful.) Given how big today's disks are, and the small size of the system, I'd go with mirrored disks for everything. > Is there any way to put the existing SATA array on a different card (say, a > PCIe > 1x SATA RAID card) without having to rebuild the volumes? Moving RAIDed disks to new RAID cards is tricky at best. That said, if you stay within the same card manufacturer, it is usually possible. I would look to replace the existing RAID card with something with enough ports for both the inside disks and the external disks I don't think putting disk I/O on a PCIe 1x slot is a good idea, so I'd stay on the PCIe 4x slot. AFAIK, all of Dell's RAID cards are rebadged LSI Logic MegaRAID cards, so if Dell doesn't sell a suitable card, you might be able to switch to something from them.
