I would not confuse these Escalade controllers with the sub-par hardware performance of Ide raid controllers like the Promise 100s. The technology on the Escalade controllers, 2nd generation, is extremely stable and fast. I get regular 89/95 MB/s (write/read) performance on an 89 Gig RAID 10 array, made up of 4 IBM 45G Deskstar HDs. The FreeBSD system treats the Escalade controller as a kind of SCSI RAID card. > Additionally, does anybody know if they can be combined (i.e. 2+ controllers > for a single partition)? This I do not know.

All you have to do is install the drives, install the controller, set it up in the BIOS, create the twe0 device in BSD, and then add your partition to the array with standard technique. easy!
