I've had my Maxtor D740X 7200 RPM ATA/133 40 GB drive for over a year now and it works great. I don't know if it's the ATA/133 interface, 7200 RPM, or a combination of the two, but it's much faster than the previous 30 GB 5400 RPM ATA/100 Maxtor I had before it. Here's a quick overview of their warranty coverage from
Maxtor.
