Micron advances in servers "consumer" NAND MLC

We are witnessing, as growing and expanding distribution of memory NAND TLC. In the server segment, this is still not particularly feel, good memory NAND MLC (with a two-bit cell) more amenable to some improvements. For example, the company in a series of Micron SSD M600 proposed the following scheme of the memory array type MLC. Before filling half the size of a drive, memory cells are in a state of pseudo SLC (with one-bit cell). This greatly speeds up the SSD and at the same time increases the resistance of cells to wear. After filling the SSD at half capacity, the cells go into a natural mode NAND MLC. Something like this company Micron has offered for the server market.

The dual-mode server NAND-flash memory Micron received the commercial name FortisFlash. The first such memory in their arrays for data storage has become used by IBM. Memory FortisFlash, as claimed by Micron, makes it possible to increase the wear resistance of cells without compromising performance. In the past, the server segment of the company Micron offer so-called memory eMLC (MLC enterprise-class). To increase the service life of eMLC had to sacrifice performance. With memory FortisFlash this will not happen.

In fact, if we ignore all this marketing husks, drives based FortisFlash this same consumer SSD Micron, only to support an expanded set of software tools for fine-tuning. The operator can select the desired him at this time, the balance between performance and resistance to wear. In general, now everyone is himself a doctor. Unfortunately, the physics of the process yet nobody has been able to deceive. And yourself – no problem.
