Western Digital VelociRaptor (WD1000DHTZ) 1 TB Hard Disk Drive

Western Digital recently launched their third-generation VelociRaptor hard disk drive, which continues to be the world's only 10,000 RPM hard disk drive with a SATA interface. The third-generation VelociRaptor improved on its predecessor by using Advanced Format Technology (AFT) and higher-density platters to deliver not only 1 TB of storage capacity but also a sustained throughput of 200 MB/s. Take a look at its key features :

- Ultra fast
- Rock-solid reliability
- Ultra-cool operation
- Advanced Format (AF)
- IcePack™ mounting frame
- NoTouch™ ramp load technology
- Pre-emptive Wear Leveling (PWL)
- Rotary Acceleration Feed Forward (RAFF™)

We did a short analysis of the drive earlier, but we are now able to produce a full review, after extensively testing this drive. Let's take a closer look!

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!
