Western Digital 320 GB Scorpio Black Notebook Hard Disk Drive

If you were impressed with the performance of the 5400 RPM Western Digital Scorpio, you will be astounded by the "higher-end" Western Digital Scorpio Black.

Running with a higher spindle speed of 7,200 RPM and boasting twice the cache of a Scorpio, the Scorpio Black represents the epitome of Western Digital mobile hard disk drive technology.

We had the opportunity to give their top-of-the-line 320 GB Scorpio Black for a test drive and we were most impressed with its performance.

Not only did it deliver a large storage capacity, it also delivered excellent results in our benchmarks. In fact, it had the same platter-to-buffer transfer rates as the 500 GB Western Digital Caviar GP desktop hard disk drive!

Our Review System

Tech ARP is committed to developing new ways to improve your experience with us. As part of our continuous efforts to improve the value of our reviews to you, we are implementing a multi-tier review system.

This review system is designed to allow you to quickly receive information on the latest hardware or software. This new system also allows you to quickly get the gist of the review without reading through it. This can be very useful, especially in situations where you need to make a quick purchase decision.

In this new system, we start with a Product Overview whenever a company sends us a press release about their latest product. We shift through extraneous PR-talk to create a straightforward summary of the product's features as well as specifications. This allows you to quickly find out all the pertinent details about the product, without reading through official press releases.

When we receive the product for review, we will quickly take photos of it and create a Pictorial Review. The purpose of a pictorial review is to allow you, the reader, to quickly examine the product visually. It may help you make better purchase decisions, especially if you cannot wait for the full review.

After thorough testing, we will post a Comprehensive Review of the product. This adds on to the pictorial review with comprehensive test results and our final conclusion on the product.

But no matter whether you are reading a Pictorial Review or a Comprehensive Review, you can always read the summary of the review as well as examine the product's specifications right on the first page. In all our new reviews, we will maintain the first page as a Product Overview page. If the product is listed in PriceGrabber, you can also check out the lowest price online.

We hope this new review system will make your experience a lot more enjoyable and informative!
