I completely agree that if what you need is throughput, then a true hardware RAID is the way to go. That's why I use the Escalade. :-)
Software raid on the same disks with a 2gig CPU is faster than your escalade. In fact its been this way since CPUs climbed above 900mhz.
Software raid gets a bum rap because its often married up with cheap IDE and then compared against high end scsi solutions.
What's the CPU overhead like? To be honest, I haven't attempted to use the software raid driver since my P3-500... and it wasn't doing to hot then. I also keep the servers fairly taxed. I'd be interested in hearing what you would envision as a decent software RAID solution. Right now with the 3Ware, I've got it set up as 4 disk RAID-5 with a hot spare. -John
