One thing I would like to point out, is that if you use the eSATA connection, you may have to alter the drive a bit. During testing I could not get the computer to recognize the drive in the BIOS. I tried for hours until something told me to remove the back port shield from the enclosure because it didn't look like the eSATA cable was going all the way in. As soon as I did this it worked fine. On the RX81-MP enclosure sent to me for testing, the back plate was too thick to allow the cable to go all the way in, and the hole was not big enough to allow it to pass. I tried several eSATA cables and neither worked with the back plate on.
