That's what I've observed. On my Windows box, it updated the driver and 
I lost RAID.

I'm a big fan of 3Ware SATA controllers. They're extremely reliable, and 
if you drop a drive it's very straight forward on how to proceed. They 
also have a pretty decent manager/web interface that can email you if 
something's going on. I can't tell you how many times I've found a 
customer box with a failed RAID array because it ran degraded for two 
years before finally failing.
