Not all solid-state drives are created equal – some are for use in personal computers and notebooks while others must work in tough conditions. If you face the second situation then Micron has something for you – the corporate class M500DC solid-state drive line.
The new SSD line is designed for use in industrial equipment and data centers and includes four models with capacities of 120 GB, 240 GB, 480 GB and 800 GB, all powered by the Marvell 88SS9187 controller. The drives make use of eMLC NAND flash memory produced on 20 nm tech process and come in two versions – with thickness of 1.8 inches and 2.5 inches. All of them support the SAS data exchange protocol that provides up to 6 Gbit/sec of data transfer speed.
Here are some performance numbers – the sequential read speed of the new drives reaches 425 MB/sec, while the sequential read speed ranges from 200 MB/sec for the 120 GB model to 375 MB/sec for the 480 GB and 800 GB models. The 240 GB version sits in the middle with 330 MB/sec of sequential read speed. IOPS numbers range from 63 000 to 65 000 for reading and from 23 000 to 35 000 for writing.
The price of the new models is unknown at the moment.
