Intel X25-M G2 (34 nm) 160 GB Solid State Drive

Intel is one of the world's leading manufacturers of solid state drives (SSDs) and NAND flash memory chips - the very foundation of solid state drives and USB flash drives. They currently offer three lines of solid state drives :

  • Intel X25-E Extreme SSDs
    - Extreme performance and reliability for servers, storage and workstations
  • Intel X25-M Mainstream SSDs
    - High-performance 2.5" SSDs for laptops
  • Intel X18-M Mainstream SSDs
    - High-performance 1.8" SSDs for netbooks

The Intel Mainstream series of 2.5" SSDs feature a native SATA interface with support for Native Command Queueing (up to 32 concurrent operations ), and an advanced architecture that employs 10 parallel NAND flash channels to deliver very fast transfer rates while utilizing multi-level cell NAND flash memory to reduce cost and increase storage capacity. To improve reliability, these mainstream SSDs use a proprietary write-leveling algorithm to spread the writes over the entire drive.

There are actually two variants of the X25-M mainstream SSD - the first-generation X25-M which is based on 50 nm NAND flash memory, and the second-generation X25-M based on 34 nm NAND flash memory. Today, we will be taking a look at the second-generation X25-M mainstream SSD, one with a storage capacity of 160 GB.

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!
