Western Digital VelociRaptor 1TB
Western Digital ships their review samples in OEM packaging so we don't have the retail package to show today.
The latest VelociRaptor retains the 2.5" form factor for the actual drive. Western Digital has used this method for several years now with this product line. The outside case acts as a heatsink to keep the 10,000 RPM drive cool while at the same time gives the drive a 3.5" form factor.
Western Digital usually releases an enterprise model after the consumer release. The enterprise model does not ship with the extra case. From time to time these show up on Newegg, but if you are not running a computer case with a lot of cooling, you are much better off with the consumer model.
The mounting points on the bottom and sides are where they should be and conform to the 3.5" form factor standards.
The SATA power and data ports are also offset to the left where they should be.
On the side we get a good look at the cooling fins that keep the drive cool.
