While running through our performance suite (i.e., with acoustic management disabled), the 536DX's seeks are pretty noticeable. They're not any quieter than contemporary 7200 RPM offerings such as Western Digital's BB series or Maxtor's own DiamondMax Plus 60. After extended use, the 536DX is fairly warm to the touch. Nonetheless, it should be usable in all but the most cramped cases.
Overall, though it aided Maxtor in edging out Western Digital to be the first at the 100 GB ATA plateau, the 536DX doesn't otherwise stand out in any real way. Those who require more than 60 gigs of dirt-cheap storage may be interested. Others, however, are better off waiting for more inspired offerings from the competition... and undoubtedly from Maxtor themselves.
