There is a _Linux_ diagnosis app, but I have no clues whether that works
with FreeBSD in Linux emulation.

I'd used an LSI MegaRAID SCSI 320-1 for a short time ("just to see if it
works") with 5.1 last fall, no problems w/ RAID level 5 on three Fujitsu
MAP3367NC, peak read in excess of 130 MB/s, write-through cache (no
battery backup unit installed yet), write rate was untested.
I didn't bother to test install the Linux diagnosis app in FreeBSD. It
works fine in SuSE Linux 9.0 though after one's gotten used to the
common confusion that a commercial software causes, usually WRT the user
interface.

The configuration/management stuff is a "Web BIOS" thingy that is
accessed during BIOS boot. Suffices for applications that allow down
times as the re-building of a replaced drive does not require
intervention -- as can be expected from controllers in the 500+ € range.
