Eek - now I'm glad I wait a few months before buying each disk for my NAS.

Not doing it for this reason but rather financial ones :) But as I have a totally mixed bunch of sizes I have no RAID and a disk loss would be horrible.

Have to be careful doing that too or you'll end up with subtly different revisions of the same model. This may or may not cause problems depending on the drives/controller/workload but can result in you chasing down weird performance gremlins or thinking you have a drive that's going bad.
