I have one of these (it's in my mirror box).

It's okay.  It's not stunning, and I lost the array once (due to a
bad drive and loose connectors more than the card).  It runs under
CentOS 3 without special drivers, but Adaptec also has some driver
software (not sure whether it's newer or not -- it's ``minimally
tested'' according to them).

I also have an Adaptec 1210SA (two-port SATA), which is running
under Debian with a custom kernel as I couldn't get it working (at
all) under CentOS at the time I was building the machine.  That
card is a complete POS -- forget about hardware RAID, but it works
okay with software RAID.

If I had it to do over again, I would definitely go with 3Ware
cards over the Adaptec cards.  What you might save in money isn't
worth the hassle.
