I can believe it. Linux SW RAID is _VERY_ fast. The advantage of 3ware
HW RAID is in its convienence and robustness when Bad Things (tm)
happen, not its performance, in my experience.
I have used both 3ware, linux software raid and others.

That is what I use.
If performance becames an issue, I just add another server.
