Micron Technology on Tuesday announced its highest capacity laptop solid-state drives (SSDs) based on its smallest circuitry technology; the largest SSD doubles the amount of data that can be stored compared to its predecessor.

Micron’s new RealSSD C400 flash drive line offers capacities ranging from 64GB to 512GB and will be available in 1.8″ and 2.5″ form factors, both supporting a 6Gbit per sec serial ATA (SATA) interface. The SSDs are based on Micron’s latest 25 nanometer (nm) NAND flash lithography technology.



Per Macworld, the C400′s predecessor, Micron’s RealSSD C300 drive, was its first to leverage the SATA 3.0 specification, which offers 6Gbit/sec. throughput, and the Open NAND Flash Interface (ONFI) 2.1 specification, which provides sequential read speeds of up to 355MB/sec. and sequential write speeds of up to 215MB/sec. The C300 also came in 1.8″ and 2.5″ models, with either 128GB or 256GB of capacity.

Crucial, a division of Micron, will begin selling the new SSD portfolio under the name Crucial m4 SSD. The Crucial m4 SSD product line is expected to be available online and through select global channel partners in the first quarter of 2011. Micron is not offering pricing information on the new SSDs.

The new drives achieve read speeds of up to 415MBps, which is 17% faster than Micron’s C300 SSDs. With write performance varying by capacity, the new 512GB drive delivers up to 260MBps write speeds, which is 20% faster than the C300 SSDs .

Micron is currently working with notebook manufacturers to qualify its new RealSSD drives, with samples of the RealSSD C400 drives available now. Micron expects mass production to begin in February.

Stay tuned for additional details as they become available.
