no! 3ware was rather early in this business, but there are plenty of
(IMHO, and some other people's opinion) better alternatives available.
3ware has good Linux drivers, but the performance of their current
controllers isn't that good.

Have a look at this: http://www.tweakers.net/reviews/557/1

especially the sequential writes with RAID-5 on this page:

http://www.tweakers.net/reviews/557/19

We have been a long-time user of a 3ware 8506 controller (8 disks,
RAID-5) and have purchased 2 Areca ARC-1120 now since we weren't
satisfied with the performance and the 2TB per array limit...
