I'd try the 3ware. AC and others have reported good throughput and, at least compared to SCSI, they aren't that expensive and claim to support JBOD. I just checked on pricewatch and the 7506-4 can be had for about $250US and the eight port for about $375. Older models can be had for less. When the economy picks back up enough to improve my bank ballance i'm planning to buy a few. > I'll run as many RAID configs as make sense, whatever the hardware > supports.
