Corporate users are experiencing a growing need for faster capacity disk systems . Growing speed data channels. And increasingly, it turns out, that traditional hard drives, magnetic plates no longer satisfy the needs of businesses.
Following the trends and needs of the market, Micron Technology company has introduced a new series of drives M500DC. New product designed for use in data centers and industrial equipment.
As the controller is used the good old familiar Marvell 88SS9187, and the role of flash memory used new eMLC NAND crystals of 128 Gbps standards issued under 20 nm process technology. To improve the reliability and integrity of the data applied technology XPERT (Extended Performance and Enhanced Reliability Technology), and in the most capacious model also improved significantly hidden spare area: the physical volume of 1TB drive available to the user only 800 GB.
M500DC is available in two form factors: 1.8 "( thickness 5 mm) and 2.5" ( thickness 7 mm), and as the connection interface is used SAS bandwidth 6 Gbit / s.

As we can see from the table, only for the oldest model allowed two and a half thousand write cycles, and for less intensive version, this figure is almost four and a half thousand cycles . Related Products :
