Thanks for the link. Their comparison with TMS's RAMSAN is a bit unfair, though. A good part of the price-difference between the two comes from the fact that the later connects via FC and it's actually a small SAN-array (hence the name). Makes all the eSATA-crap unnecessary and allows for easier sharing of the device. But still, the Hyperdrive looks promising. The problem is: our servers don't come with 5.25" bays anymore - we've long since left that form-factor behind.... cheers, Rainer -- Rainer Duffner CISSP, LPI, MCSE rainer@ultra-secure.de
