and also to keep all of the drives the same make/model... you don't want to create a RAID with different types of drives.
Apparently this isn't necessary anymore. I configured a HP server with a couple of RAID arrays. HP sent two different makes of drives, and initially I was going to send them back. Until I read a great big warning notice that said not to send differing makes of drives back, as HP warranted them for use in RAID arrays and there would be no problem as they'd tested them to work together.
Fast forward about a year and those arrays are singing along with no problems.
