Western Digital Blue (WD10SPCX) 1 TB Slim Mobile Hard Disk Drive

The new WD Blue drives also come in slimmer form factors with heights of just 7 mm and 5 mm, allowing them to fit in ever thinner Ultrabooks. In addition, they offer these key features :

  • Low Power Consumption - State-of-the-art seeking algorithms and advanced power management features ensure low power consumption and long battery life.

  • Quiet - In a notebook drive, silence is golden. WD’s exclusive noise reducing technologies yield one of the quietest 2.5-inch hard drives on the market.

  • Available SATA 6 Gb/s interface -The SATA 6 Gb/s interface provides greater flexibility for use with the latest chipsets as well as backwards compatibility to legacy systems with SATA 3 Gb/s requirements. (xPVX, xPCX, and MPCK models only).

  • 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.

When Western Digital launched the WD10JPVT, a 1 TB Scorpio Blue drive, it featured two of their new high-capacity 500 GB 2.5" platters. The drive was thus able to fit standard 2.5" storage bays. If you recall, the original 1 TB Scorpio Blue drive (the WD10TPVT) had a thickness of 12.5 mm, which prevented it from fitting most 2.5" storage bays, thereby relegating it mostly to special applications like portable USB drives.

Even so, the standard 9.5 mm form factor of the WD10JPVT was too thick for the Ultrabooks. To accommodate these thinner notebooks, Western Digital created the WD10SPCX, which is basically an improved 7 mm version of the WD10JPVT. It sports two of the same 500 GB Advanced Format platters in a slimmer form factor, with double the SDRAM cache and a faster SATA 6 Gb/s interface. But will all that translate into better performance? Let's take a 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!
