Except for the lower power consumption (and very slightly higher price) of the AACS, what are the differences between these two?
This is the information my usual shop gives on these two:
WD6400AACS
Transfer rate: up to 98 MB/s
5400 rpm
8.9 ms access time
27 dB(A)
WD6400AAKS
Transfer rate: up to 93.5 MB/s
7200 rpm
8.9 ms access time
33 dB(A)
It seems a bit odd that despite the lower rpm, the AACS allegedly achieves the same access times and *higher* transfer rate...
