I've used 3ware SATA RAID cards (8xxx and 9xxx series) for a long
time, in several servers, and I love 'em. They work far better than
any SCSI RAID cards I've used (except for raw speed, of course. SCSI >
SATA) and are supported very well under Linux and FreeBSD.
I don't know how well they work with Linux "hotplug" stuff, but I do
know that you can hot swap the drives within RAIDs easily, as that's
all handled by the card itself.
