Are you sure about the Software RAID on this 3ware adapater?? I was
under the impression it's a HW Raid adapter?
(I have a preference to HW RAID if available...)
The 3Ware is a very good hardware RAID device.
That is irrelevant in this context.
One of the many advantages of software RAID is the ability to use multiple controllers in separate PCI slots ( and in many cases on multiple PCI buses) to accomplish much better throughput and I/O rates.
I could perhaps agree with your preference for HWare RAID IF:
1) It could be spanned over multiple controllers
2) It could allow one to create non-RAID boot partitions on the disks used.
3) It could compete for RAID5 performance with software RAID on a modern machine.
