Western Digital Caviar Black 2 TB Hard Disk Drive Review

Western Digital Caviar Black 2 TB Desktop Hard Disk Drive

Western Digital's Desktop Storage line covers three different products :

  • WD Caviar Black - for high-performance applications
  • WD Caviar Blue - performance and reliability for everyday computing
  • WD Caviar Green - cool, quiet and eco-friendly drives

Caviar Black and Caviar Blue drives run at the same spindle speed of 7200 RPM, but there are some fundamental difference between the two lines. The Caviar Black drives, for example, feature dual processors and generally have a larger cache. Let's take a look at the key features of the WD Caviar Black 2 TB hard disk drive (WD2001FASS) :

  • Dual Processor - Twice the processing power to maximize performance.

  • Large Cache - Bigger, faster cache of 64 MB means faster performance.

  • Dual actuator technology - A head positioning system with two actuators that improves positional accuracy over the data tracks. The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy. (2 TB only)

  • StableTrac - Secures the motor shaft at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations.

  • NoTouch Ramp Load Technology - The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.

Let's find out how well this drive performs!

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!
