Western Digital Scorpio Black (AFT) 750 GB Mobile Hard Disk Drive

There are two fundamental differences between the two drive families - spindle speed and storage capacity. The Scorpio Blue drives spin at 5,400 RPM and have a maximum capacity of 1 TB. The Scorpio Black drives, on the other hand, are limited to a maximum capacity of 500 GB but have a much higher spindle speed of 7,200 RPM. The Scorpio Black drives offer these key features :

  • Desktop-class performance for notebook computers - With 7200 RPM spin speed, 16 MB cache, and capacities up to 750 GB, these drives enable you to have the best of both worlds: the capacity and performance of a desktop PC with the convenience and portability of a notebook.

  • Low power consumption -With technologies like IntelliSeek, which calculates optimum seek speeds to lower power consumption; and SecurePark, which reduces power by parking the heads during low power idle mode, this drive delivers 5400 RPM-equivalent power consumption in a 7200 RPM drive.
  • Quiet - In a notebook drive, silence is golden. WD's exclusive WhisperDrive™ combines state-of-the-art seeking algorithms to yield one of the quietest 2.5-inch hard drives on the market. These algorithms also optimize the way a drive seeks for data, which significantly improves power consumption. So now silence (and longer battery life) is golden.
  • Reliable and rugged - WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks. WD's SecurePark technology parks the recording heads off the disk surface during spin up, spin down, and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long term reliability due to less head wear, and improved non-operational shock tolerance.

Today, we will look at the ultimate drive from the Scorpio Black family - the 750 GB WD Scorpio Black (WD7500BPKT) hard disk drive. With 750 GB of storage capacity packed into just two platters, this drive promises to provide the best combination of performance and storage capacity.

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!
