[Thomas Morter-Laing] "Very very interesting, so the ones at work may indeed have slightly better internals, even if the difference is only tiny. Do you randomly know if there's a utility (windows or mac) that can give me some indication about what the internal drives are of these G-RAIDs? There a warranty sticker covering one of the screws :S"

The main difference is the rotational vibration sensor. That's what allows the drive to keep its latency down while operating in a ganged environment. One day, we'll all have SSDs and it won't matter :)

To figure the drives out, it depends on the hardware setup. If the drives are *on* the SATA bus and the OS can see them as individual drives (that are software striped) you can see them in the system profile. If they are sitting on their own bus (hardware raid), then the OS can't see them and no utility will be able to see them either. You'll need the RAID vendors utility. Atto will show you the drive info for example.
