Anyone with any experience with the 3ware controllers that could
comment on them.
In particular the literature for the controllers has:

"Diskswitch architecture replaces the shared bus found in SCSI
systems with a multiplexed data path that speeds data into
system memory without burdening the host CPU"

Does that mean that to FreeBSD these controllers act like SCSI
controllers?
Anyone compared them to plain IDE drives or an SCSI Raid in
terms of CPU utilization and performance?
