Remember when it comes to OLTP, massive serial throughput is not gonna help you, it's low seek times, which is why people still buy 15k RPM drives, and why you don't necessarily need a honking SAS/SATA controller which can harness the full 1066MB/sec of your PCI-X bus, or more for PCIe. Of course,
hm. i'm starting to look seriously at SAS to take things to the next level. it's really not all that expensive, cheaper than scsi even, and you can mix/match sata/sas drives in the better enclosures. the real wild card here is the raid controller. i still think raptors are the best bang for the buck and SAS gives me everything i like about sata and scsi in one package. moving a gigabyte around/sec on the server, attached or no, is pretty heavy lifting on x86 hardware. merlin
