Yup, which is why I use 'em. When I do it I try to use drives from different makers or batches. You can also get some speed up on read operations when multiple programs are trying to read different areas of a disk. Writes are perhaps a hair slower than single disk.
I also do software RAID. When the OS disk for a debian apt mirror I maintain died I was able to move the RAID drives to a new machine, reboot the existing OS, set up the mdadm.conf file, reboot,and the data was accessible and intact.
