Yes, and very fast as well. Do note that if you (a) need to boot from a 
recovery CD and (b) have a low memory machine which really needs swap 
early, most of the ones I've tried don't use such a swap, you have to 
start it by hand. Also, I have not tried suspend to disk and restore 
using RAID-10, it's on my to-do list, but *way* down.

But in general you will find it very fast and reliable.
