| Western Digital 750 GB Caviar SE16 Serial ATA Hard Drive |
The number 16 in SE16 refers to the size of the onboard disk cache. All Caviar SE16 drives have a large 16 MB SDRAM buffer. They also make use of Perpendicular Magnetic Recording to achieve a high areal density for greater storage capacity and improved performance. At press time, Western Digital has six Caviar SE16 models with capacities from 250 GB to 750 GB. The model we are reviewing today is their 750 GB model which uses four platters to deliver its large capacity. Will it be significantly faster than the 1 TB Caviar GP which impressed us with its high performance, or will the Caviar GP turn out to be a better buy? For more details, read our Comprehensive Review! To discuss about this review, head over to the forum thread! |
This Western Digital Caviar SE16 family is Western Digital's range of performance-grade desktop hard drives. Unlike their GreenPower (GP) series, the Caviar SE16 hard drives have a spindle speed of 7200 RPM.| MSRP |

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!
