Western Digital WD400
The latest high performance drive from Western Digital is called WD400 and also comes with two platters at 20 GB each, making a total of 40 GB storage. Thanks to 2 MB buffer and a rotation speed of 7200 rpm, the benchmark results are quite good. Unfortunately, the drive is not as quiet as the Fujitsu one. Even after closing the computer case we could still clearly hear the WD400 working.
WD also offers two smaller drives WD200 and WD300 at 20 and 30 GB. Each comes with ATA/100 interface and 2 MB cache memory. Those WD drives are also equipped with the acoustic management feature, but you will have less benefit due to the higher spindle speed. While acoustic management reduces access noise, it won't make the 63 dB of idle noise disappear.
