The V20400's quiet operation cannot be overemphasized. Even when running the seek-intensive IOMeter suite, Samsung's drive was inaudible over the testbed's PC Power & Cooling Silencer power supply when listening from a distance of just one meter. Low idle and seek noises make the V20400 the quietest drive that we've yet reviewed here at SR. As difficult as it seems, Samsung reduced noise levels down a notch below that emitted by its older drive as well as ultra-quiet units from Quantum and Fujitsu. The drive becomes just slightly warm to the touch even after extensive use in our smallish testbed case.
In conclusion, the Spinpoint V20400 delivers a mixed bag when it comes to performance. Though its low access time delivers admirable IOMeter scores, its WinBench 99 scores are decidedly below par. When it comes to quiet operation, however, the V20400 is second to none. This alone may be reason enough for many to consider it.
