Micron Technology on Tuesday introduced its next-generation solid state drive (SSD) for data center servers, appliances, and storage platforms that manage the volume and velocity of big data. The new Micron P400m SSD is a high-endurance SATA caching and storage solution that was designed from the ground up for maximum endurance, reliability and performance possible.

"The growth in big data is placing tremendous pressure on IT administrators. Users require fast, on-demand access to data. This means data centers must deliver more data, faster than ever before – in an environment that has zero tolerance for data loss. Integrating flash storage into the data center is the preferred way administrators can meet these growing demands. The Micron P400m delivers the endurance, reliability, and performance critical for data center storage," said Ed Doller, vice president and general manager of Micron's enterprise SSD division.

Micron’s P400m solid-state drives come in 2.5”/7mm form-factor, feature Serial ATA-6Gb/s interface and are available in 100GB, 200GB and 400GB capacities. The drives provide up to 350/300MB sequential read/write performance and up to 55000/17000 read/write IOPS performance. The drives consume less than 5W during active usage and less than 0.75W in idle mode.

Micron P400m solid-state drives are based on specially-designed and manufactured high-endurance NAND flash memory. The newly-developed MLC-HET NAND flash memory is made using 25nm process technology and is not available for sale, which means that Micron uses the memory exclusively for the P400m. The P400m SSDs are powered by Marvell’s controllers with custom Micron IP. The new SSDs also implement Micron's extended performance and enhanced reliability technology (XPERT), which closely integrates the storage media and controller through highly-optimized firmware algorithms and hardware enhancements. XPERT is designed to achieve 10 drive fills per day for five years.


Micron XPERT feature-set includes:

  • Adaptive read management/optimized read (ARM/OR): a dual-faceted data management technique with both proactive and inline protection. In proactive mode, ARM/OR ensures that data stored on the SSD is immediately available by sampling the stored data and dynamically tuning the NAND device in the background. This tuning, based on Micron-specified thresholds, is completely transparent with no effect on drive or system performance.
  • Redundant array of independent NAND (RAIN): by calculating and storing additional protection that is parity, Micron’s RAIN provides data protection well beyond common error correction code (ECC) implementations. Micron SSD controllers have built-in data acceleration engines that streamline RAIN.
  • DataSAFE: protects user data as it moves from the host to the SSD interface, through the data path inside the SSD, into the storage media, and back. In addition, DataSAFE embeds the host logical block address (LBA) with the host data before storing both in the drive. Storing this additional information (also known as metadata) helps to ensure that XPERT-enabled SSDs return the exact data requested.
  • Reduce command access latency (ReCAL): enables lower maximum command/access latency by managing internal operations at a more granular level to ensures smooth, stable performance for enterprise operations.

All manufacturing, testing, and qualification for the Micron P400m is completed solely at Micron facilities. Close communication between Micron NAND and SSD engineers enables the highest degree of integration between the flash media and its management, and the in-house manufacturing ensures complete quality control during the entire drive development, test, manufacture, and shipment process.
