Samsung sampling multi-cell SSDs for servers

Korean electronics giant Samsung has announced that it has started sampling a new line of Solid State drives aimed at server applications.

The company started rolling out 100, 200 and 400 gigabyte multi-level-cell (MLC) SSDs earlier today and hopes to be mass producing the units in commercial quantities next month.

Samsung is aiming the storage at enterprise-level servers, a market already well served by its own single level (SLC) NAND architecture. The increased density of the MLC NAND flash allows more storage in a smaller space whilst using less power, but Samsung reckons MLC performance is catching up with SLC and in some cases even overtaking it.

The outfit says it is using '30nm class' silicon in the production of the NAND, but in reality this could mean anything between 30nm and 39nm.

The new drives can process random read commands at 43,000 input/outputs per second (IOPS) and random writes at 11,000 IOPS. This compares to a 15K RPM spinning platter HDD which has an IOPS rate of 350, amounting to a 120X gain in random IOPS read performance and a 30X gain in random IOPS write performance, according to Samsung's benchmarketing.

The same mechanical drive would also use up to 150 times the energy to do the same job according to Samsung's numbers.
