Crucial RealSSD m4 Promises 415 MB/s Performance

  • By Lexar Media, Inc.

Micron C400 Solid State Drive series utilizes Micron 25nm MLC NAND Flash

Continuing the tradition of our award-winning solid-state drives, the Crucial m4 offers mobile and desktop users scorching-fast read and write speeds, groundbreaking SATA SSD computing, and unparalleled performance for the dollar.

Designed for client computing, the Crucial m4 SSD delivers faster boot and application load times for mobile and desktop users alike. Low power, lightweight, and durable, it empowers high-speed synchronous MLC NAND, advanced controller technology, optimized NAND management, and the second-generation SATA 6Gb/s interface.

Together, that technology dramatically improves data transfers for bandwidthdemanding applications.

Delivering on the highest quality based upon Micron's leading-edge NAND media, the Crucial brand of SSDs has long been synonymous with reliability and high performance. And because we're part of Micron, the m4 was bred and built entirely in-house. So you can rest assured you'll get one of the highest quality products available-from the company that knows memory.

SSDs provide many benefits over traditional hard drives. You'll enjoy reduced power consumption, less heat generation. Because they have no moving parts, SSDs are quiet, more lightweight, and they're rugged and reliable even in the most demanding operating environments or temperature extremes.

Crucial m4 series employ a standard hard drive interface and dimensions, so it is an easy storage upgrade for most notebooks. We guarantee compatibility.
