Micron announces solid-state drive line

Micron Technology Inc. has introduced the RealSSD family of solid state drives, which offers a range of form factors and densities designed for computing, enterprise server and networking applications. The devices in this new family include 1.8-inch and 2.5-inch SSDs for notebook and desktop computing with 32Gbyte and 64Gbyte densities. Micron is now sampling both devices with mass production expected in the first quarter of 2008.

Moving the NAND-based storage architecture forward, the SSDs vary in density from one to 64Gytes. Compared to hard disk drives (HDDs) they provide lower power, faster boot-up time, increased reliability, improved performance and reduced noise.

Micron's RealSSD SSDs feature a native-serial-ATA II interface. They use a single-chip controller specifically targeted at the SSD application, and do not require a serial ATA bridge chip like most current solutions. The controller is optimized for four channel control of the NAND and supports advanced serial ATA features such as native command queuing allowing the drive to reorganize read and write commands. It also features a serial ATA hot plug allowing for the drive to be removed from the system without eliminating power.

The devices use less than 2W of power while active, with dramatically lower power idle and standby modes. In addition, without platters to spin up, worst-case power consumption is greatly reduced.

They are packed in rugged, lightweight plastic casing, allowing for at least a 50 percent reduction in weight when compared to similar density HDDs, which is of particular importance for the ultra mobile PC market.

The family also includes RealSSD Embedded USB products that range in density from 1-8GBytes of storage and are designed to be integrated into a system through an embedded USB 2.0 interface. This provides a cost-effective solution to store and boot an entire operating system within an industrial PC or blade server system or it could be used as a reserve for often accessed files.

The RealSSD Module provides customers with a customizable form factor that goes beyond a legacy HDD enclosure and provides significant footprint reduction, ease of installation and weight savings. Micron's RealSSD Module is essentially a solid state storage device in a low profile module form factor. Using a commonly available serial ATA interface, these modules are designed to be 25mm high x 133.5mm long x 4mm thick, allowing for increased system airflow, a key value proposition for enterprise server applications.

"SSDs are becoming the new storage medium, fundamentally altering the way data is stored," said Dean Klein, Micron vice president of memory system development. "The storage market is ripe for innovation, and it's an opportunity Micron is embracing given our expertise in NAND. We know how to manage NAND flash to work best with controllers, allowing us to develop an optimized SSD solution for every application."
