We just got a machine with a 9550SX on it.
It was a hassle installing FreeBSD on it. Had to boot a loadable module from
a floppy. Once the machine was upgraded to 6 Stable it was fine since the
driver for the card was added in early December to the source tree.

I have read very good reviews and good feedback on other lists. Also they
are one of the few cards that can do RAID 6 (parity distributed to 2 disks).
The reason we went with 3Ware in the latest server is because the vendor of
the machine mentioned that 3Ware had a unique technology which would better
safeguard the data upon power loss. He said that one would have to turn off
the cache in the Areca to be as safe as the 3Ware.. and that the 3Ware with
cache enable was safe.. as long as one got power back before the card
batteries ran out.

Have seen a few reviews where the Areca's did better, but according to the
an engineer where we bought our latest server the 3Ware 9550SX outperforms
the areca offerings.
