Vibrations, noise level

Disc Operating Noise

Thanks to only 5,400 rpm, the WD drive neither makes bothering noises, nor does it generate noticeable vibrations. Usually, your power supply fan will be louder than this drive, so you should only hear the read or write accesses (the heads' movements). The lately review drives 153BA and 205BA have also been real gentlemen, running at a low vibration level in spite of their high rotation speed. Of course this also applies to the 45 GByte model, which calls even less attention thanks to the low rotation speed.


High rotation speeds cause higher friction, thus also more heat than models running at 5,400 rpm. As a consequence, the 450AA is able to score lots of points in this discipline, as we measured 37єC (99єF) max. The drives of our first hard drive review heated up to between 39єC (102єF) (Western Digital as well) and 50єC (122єF) (Seagate). All temperature measurements are done at approximately 20єC (68єF) and outside the computer case, but even after installation into a computer case this drive will certainly never reach critical temperatures (60єC/140єF and more).

CPU Load

The WD drive doesn't look as good here, if you compared to the previously tested hard drives. It scored a CPU load of 46%, which is worse than the scores of the majority of its competitors.

Drive Configuration

Western Digital differentiates between single drive and master mode. Single drive has to be used if your hard disk is the only drive at the IDE port. Before attaching two drives to this IDE port, you will have to decide which one will be master or slave.

Jumper Location

The jumpers have to be placed vertically from the right side.
