I have two WD 500g SATA drives:


and a WD5000AAVS

The only difference in the designator is the 'K' in one and the 'V' in the other.

I want to use these in a mirrored RAID Array, does anyone know what the differences might be based on the 'K' or the 'V'?

I am a beginner at RAID; how critically important is it the two drives be identical? For example, even though they are the same capacity and brand, they were bought about three months apart. Thanks for any guidance.

You can mix them, they have other firmware and may have different performance attributes. The only thing you really need to look after, is capacity.

If you have 500GB drives, another 500GB drive may be slightly smaller; this creates problems. So make sure the new drive is at least as large as the ones you already have.
