I've had good results with both Areca 8 and 16 port cards (arcmsr
driver) on -CURRENT and a couple of Adaptec 2410s on 5.x (aac driver).
All SATA, though the Areca did seem to perform quite a bit better
(+15-20MB/s on writes) during a bunch of quick dd tests I did using a
month old -CURRENT. I haven't used any 3ware cards myself but I've heard
good things.
With the Adaptec's it's fairly trivial to run say 2 seperate Raid5 sets
across the disks or mirror 4 the first 5GB of each of 4 disks and use
the rest of the space in RAID5, etc. I haven't tried this with the
Areca's but brielfy looking at the documentation it seems possible.
I hope that's of some help.
