You should consider the LSI Megaraid SAS as well. The aging 8308elp,
performs quite nicely with decent disks. Got one here (at home) handling
8 1T5 Barracudas in RAID50 (with coldspares), that routinely handles
400+mbytes/sec io, even in windows. It's been running in FreeBSD as
well, but until I can figure out how to get reliable backups (the MPT
issue shared with OpenSolaris) I'm stuck with windows on the box.
FreeBSD's mfiutil works works splendidly with the controller allowing
you to handle things like patrol-reads from an SSH session without much
trouble. As a SAS-controller, it "eats" both SAS and SATA disks, and
plain and simple just "works".
