Objectively speaking, the beta Raptor turns in impressively low noise floors, likely due to its single-platter design. A score of 42.5 dB/A approaches the noise floor delivered by the latest Barracuda ATA drives. Subjectively, it is interesting to note that while the final version of the drive weighs in with a higher noise floor than the beta, it tempers the high-pitched whine exhibited by the latter and thus is less obtrusive. It nonetheless still emits a very slight squeal reminiscent of third- or fourth-generation 10k RPM SCSI units. Though the sound does not bother me personally, it may irritate those who insist in ultra-quiet operation from their machines. The Raptor's seek noises definitely land significantly higher than today's ATA drives. While not quite as loud as a SCSI disk, it is nevertheless easy to tell when the drive's actuator is in motion.
que a 10k rpm tem tudo para não ser silencioso... tal como o Tafinho disse e bem.
