The last time I worked with a 3Ware RAID controller it was 2004, and it was a 9000 series SATA. It lived up to its marketing hype - I personally benchmarked it exceeding 100MB/sec on RAID5 writes - an impressive result for the time. The largest controller available was a 12-port job, so the largest array you could build was an 11 disk RAID5 - if you wanted a hot spare. Still, the combined seek performance of 11 drives was significant.

3Ware have built on this performance. Their 9500 series card claimed approximately 500MB/sec RAID5 writes, and a 16 port model. Now, with their 9650SE series, 3Ware are claiming 600MB/sec RAID6 writes (800MB/sec reads) and 24 disks in an array.

What does this mean?
