All of the controllers mentioned so far--3ware, MegaRAID (both made by LSI), and Areca--are true hardware RAID controllers. If you intended on doing md RAID you would probably not purchase one of these, but would go instead with a simple SATA/SAS controller with sufficient ports and bandwidth to host all your drives (and make sure all hardware components supported hot swap). --keith -- kkeller at wombat.san-francisco.ca.us
