OK, so I was convinced to use LVM on top of software RAID.

Any gotchas for such a setup?

For performance, I'll be hoping for near x2 read speed for a simple RAID
mirror on SATA II HDDs.

But what happens for _write_ ?
How clever is the software RAID for performance and recovery?

And what does the motherboard RAID hardware offer?
Am I best staying with the Linux software RAID?
