WD
CAVIAR BLACK 1TB
Introduction
Cavair, a symbol of
opulence, class, and discriminating taste. The
wealthy will pay through the nose for Sturgeon,
while more common folk are satisfied with grocery
store varieties that costs less than the crackers
its served on.
Just like fish eggs,
hard drives come in varieties ranging from cheap to
chic. Western Digital's Caviar Black (Part#
WD1001FALS) exudes
that sense of luxury, performance, and refinement.
Being WD's 2nd 1TB drive to market, the Caviar Black
seems to be a latecomer to the 1TB party.
Fashionably late, that is. WD's RE2-GP was the
tree-hugging, hyper-efficient drive that drew praise
for its combination of enterprise features, low
power consumption but at the expense of performance.
Now, WD pops out this younger sibling, wearing an
Italian suit, ready to take on everyone else in the
streets of 1TB-land.
Major architectural
highlights are a 32MB buffer and dual processors.
32MB buffers are the norm these days, providing
manufacturers a quick way for more speed. But
improving the engine with dual processors seems more
revolutionary. Let's hope that the combination
of these two improvements result in real-world
performance. Oh yeah, it also comes with
a 5-year warranty.

As used for
storage capacity, one megabyte
(MB) = one million bytes, one
gigabyte (GB) = one billion
bytes, and one terabyte (TB) =
one trillion bytes. Total
accessible capacity varies
depending on operating
environment. As used for buffer
or cache, one megabyte (MB) =
1,048,576 bytes. As used for
transfer rate or interface,
megabyte per second (MB/s) = one
million bytes per second, and
gigabit per second (Gb/s) = one
billion bits per second.
