The WD Scorpio Black 320GB Hard Drive

The Western Digital Scorpio Black series of 2.5-inch hard drives was designed to bring desktop-class performance into notebook computers. With a spindle speed of 7200rpm, 16MB of cache and a SATA 3 GB/s interface, you can see that this hard drive series has performance in mind. All that performance does come at a cost though, as the black series sacrifices capacity and consumes more power at idle than the WD blue series. To help offset the negatives Western Digital slapped a 5-year warranty on the Scorpio Black series versus the 3-year warranty found on the Scorpio Blue series. The black series is only available in capacities up to 320GB rather than 500GB on the blue series, but that doesn't mean you can't fit a ton of data on a 320GB Scorpio Black series hard drive.

The WD Scorpio Black 320GB is sold under the part number WD3200BEKT and WD3200BJKT. The difference between these two Scorpio Black 320GB hard drives is the fact that only the WDxxxxBJKT models are equipped with a free-fall sensor that detects when the drive is falling and, in less than 200 milliseconds, parks the head to help prevent damage and data loss. The model that we will be looking at today is the WD3200BJKT, which features the free-fall sensor. WD has color coded their products, which makes is easy to see at whom they are aimed. Their mainstream products are called “Blue,” power-efficient drives are named “Green,” and high-performance drives are called “Black.” All of the WD Blue drives spin at 5,400 RPM, utilize a SATA/300 interface with Native Command Queuing (NCQ) support, and have 8 MB of cache memory. Those wanting a little more performance should look at the Scorpio Black as it has a 7,200 RPM drive speed and 16 MB of cache memory, but it only comes in capacities up to 320GB. If you want more storage space you'll need to sacrifice a little performance!
