For quiet storage on desktop computers we often recommend SSDs and "green"
hard drives with rotational speeds of 5400~5900 RPM. Both are usually very quiet
(or completely silent in the case of SSDs) and energy efficient, but there is
a large capacity and speed gap between these two types of drives. SSDs are very
fast but still very expensive per byte those with enough storage to rival
a desktop hard drive go for well over US$1000. "Green" drives are
big and cheap, perfect for storing large amounts of data like high definition
video but aren't quite as snappy as the 7200 RPM models found in the majority
of desktop systems. Western Digital's Caviar Black 2TB and VelociRaptor 600GB
are two hard drives that bridge the gap between speedy SSDs and high capacity green drives.

With dual processors and 64MB of cache on the larger models, Caviar Black is
WD's premier performance desktop hard drive line (as opposed to the energy efficient
and middling Caviar Blue). The first Caviar
Black we reviewed in 2008 was loud and power hungry, but hopefully time
has been kind and the new 2TB version is a refined, improved revision. We don't
expect any miracles though with mechanical hard drives speed usually
comes at some acoustic cost.
For a brief period the best of both worlds was available in the VelociRaptor,
a unique 10,000 RPM 2.5" enterprise drive packed in a 3.5" heatsink/enclosure.
Removing it from its heatsink resulted in impressive acoustics at the time (though
it voided the manufacturer warranty), and with its high spindle speed and small
physical platters, it delivered top notch speed. With the arrival of faster
7200 RPM drives and SSDs, the 150GB and 300GB VelociRaptors have taken a big
hit in popularity. The new higher capacity 600GB model may have better luck keeping the SSD invasion at bay.
