There is no need for "SATA technology support". Its an affair between device and controller. FreeBSD-STABLE knows a few controller chips which are used with the SATA interface. Also a lot of manufacturers provide suitable drivers. That should be enough. I already used a RAID1 solution with two SATA hard disks and FreeBSD 4.5(!) without any additional drivers, that means with FreeBSD's built-in drivers without explicit SATA support. It worked fine. > The man page of aac says it supports "CERC SATA RAID 2", but is it > the same or at least compatible with "RAID 1 CERC SATA (6 channels)"? The only controller I discovered on Dell's homepage is called "Adaptec CERC SATA1.5/6ch" or simply "CERC SATA RAID". So I assume that this is the only SATA controller which is offered by Dell. The string "CERC SATA RAID 2" comes only up with FreeBSD, so I guess it's an erratum and they mean the same controller. I think in this case the controller will work with aac(4) properly. Bjoern
