3ware 9xxx series is much better than adaptec, Adaptec will not work with dbsd without some tweaking, 3ware will work flawlessly.
Are you running 4.x or 5.x?
I've been testing 5.3-BETA7 with an Intel SE7210TP1-E motherboard. It has Adaptec HostRAID and I'm using two Seagate 160GB SATA drives. So far things are working as expected.
I had to create the RAID 1 array with atacontrol before installing FreeBSD. Below is the output of diskinfo -t /dev/ar0 with the default GENERIC kernel. I've done no tuning yet.
