WESTERN DIGITAL RAPTOR X 150GB

Introduction
When WD launched the
74GB 2nd-generation Raptor, it simply blew
everything else out of the water, including many 15k
SCSI drives when benched for non-server use.
Many enthusiasts loved it performance, and wondered
when a new version would come out. It took a
few years, but WD eventually released this latest
version of the Raptor, sporting 150GB of storage,
10k RPM spindle speed, and doubled the cache to
16MB. Again, it simply picked up where the
74GB left off, leaving a plume of smoke on its way
to the finish line.
But wait, this Raptor X
has something special - a "bonus", if you will.
Yes, like many modders out there wanting to show off
their creations with windows and clear acrylic PC
cases, this Raptor is definitely X-rated. It
has a clear top, allowing a full view of its
spinning platters and arm work its magic. And
because it was made that way by WD, no warranties
were broken here.

Here are some photos of
the Raptor X:

It comes with its own svelte drawstring pouch.

Beautiful view of the platters through the clear
cover. AWESOME!

The PCB

The connectors. Note that the legacy 4-pin
power socket is still present, and is much
appreciated.
