From the Manufacturer

The Crucial m4 SSD

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. Theres a reason the Crucial m4 SSD has garnered numerous international awards since its launchit does what its supposed to do. No matter what kind of files youre working with on a Crucial SSD, youll experience high speeds with no drop in performance.

Unlike other SSDs on the market, Crucial SSDs treat all files the same, regardless of whether theyre 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 cant be compressed, resulting in SSDs that often deliver drastically slower speeds than originally advertised. With the advanced technology of a Crucial SSD, however, youll never have this problem!

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

Crucial SSDs. Performance you can trust.
