I understand that. My question is, does it take longer to format BECAUSE it is an array as opposed to just one hard drive.
By the way, I understand that it is best to use two identical hard drives when doing a RAID array, but is this a requirement? I have a WD 160GB and WD 250GB hard drive. I am assuming that it will still work but I will be wasting 90GB of space on the larger hard drive.
