About Crucial

Award-winning quality. Award-winning performance:
The award-winning Crucial m4 SSD delivers powerful performance gains for SATA 6Gb/s systems. Designed to empower your system, the Crucial m4 SSD offers faster application load times, faster boot times, and increased durability compared to a traditional hard drive. The results speak for themselves: blazing-fast sequential read speeds of up to 500 MB/s - for any file type

Cutting-edge technology. Quality component testing:
Built with advanced controller technology, Micron proprietary firmware and high-speed synchronous MLC NAND, the Crucial m4 SSD is engineered to deliver consistent, blazing-fast SSD performance. From the extensive research and development that led to its ultimate design, to the hours of testing and validation spent on each NAND component, to rigorous compatibility testing in the Crucial Performance Labs to ensure component functionality, the Crucial m4 SSD is built to last.

Consistently fast speeds. No exceptions and no fine print:
There's a reason the Crucial m4 SSD has garnered numerous international awards since its launch - it does what it's supposed to do. No matter what kind of files you're working with on a Crucial SSD, you'll experience high speeds with no drop in performance.

Unlike other SSDs on the market, Crucial SSDs treat all files the same, regardless of whether they're compressed or uncompressed. This is important because the files most people use everyday - videos, mp3s, advanced graphics files and zip files - are compressed files and thus unable to be compressed any further. While many SSDs on the market achieve faster speeds by using file compression, many of the most common file types can't be compressed, resulting in SSDs that often deliver drastically slower speeds than originally advertised. With the advanced technology of a Crucial SSD, however, you'll never have this problem!

Crucial-quality you can depend on:
Crucial is a trusted name when it comes to SSDs, and that's no coincidence. As a brand of Micron, one of the world's leading manufacturers of SSDs, Crucial works with their engineers to design, refine, and support their drives. With over 15 years of experience in the memory industry, NAND component testing, and the ongoing development of advanced technology, Crucial continues to innovate without sacrificing what has made Crucial great: high-quality upgrades and outstanding customer service.

Excellent & Fast, tech-savvy required


PROS: This drive is terrific, especially for those wanting to take advantage of SSD benefits without waiting on SandForce drives to work out their bugs. My avg. sequential speeds are 489MB/s (read) & 195MB/s (write). Avg random speeds are 26MB/s (read) & 70MB/s. CONS: Setting-up this drive for an OS install (in my case, Windows 7 x64 Professional) is not difficult to do, but does require reading about SSDs and their peculiarities. For example: after much research, I finally found that wiping this drive is extremely simple and takes less than 2 minutes (using third-party Secure Erase software). OVERALL: Extremely happy with product and would recommend to anyone with an interest in computing.
