We have had the same luck with IBM also. Maxtor(Diamond Max Plus) is
also very close. Except for several 15GB models(we since have dropped
that model) we have seen a 0 failure rate with them. I don't recall ever
seeing quality, price and performance like we do now. The same goes for
several brands of motherboards too. This has to be the PC's golden age.
Look at memory prices and quality. 1GB of PC133 can be had for under
$900 and again with the assurance that a failure would be pretty rare.
