Western Digital 300 GB VelociRaptor Serial ATA Hard Drive Review Rev. 3.0

Western Digital 300 GB VelociRaptor Serial ATA Hard Drive

Western Digital may be marketing their new VelociRaptor family of high-speed hard drives as enterprise-class hard drives but they are also very popular with hardware enthusiasts who just cannot resist their 10,000 RPM spindle speed. Everything just seems a little faster when you use a hard drive that spins at such a high speed.

To cater to this exclusive group of enthusiasts, Western Digital first introduced the Raptor and Raptor X hard drives with capacities of 36 GB to 150 GB. These Raptors have now evolved into the next-generation Western Digital VelociRaptor hard drives, that not only boast twice the storage capacity but also managed to do it in a much smaller 2.5" drive form factor!

Let's find out just how much faster this drive is compared to the 10K RPM WD Raptor X and 7200 RPM hard drives!

For more details, read our Comprehensive Review!

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!
