Samsung sample MLC based SSDs for enterprise storage
1 min read
Samsung Electronics has developed and started sampling 100, 200 and 400GB multi level cell (MLC) solid state drives (SSDs) for use as the primary storage in enterprise storage systems. According to senior vice president Byungse So, the company is expanding its Green memory range to include high density SSDs using MLC NAND flash memory, in a bid to keep up with current demand in the server market.
The new eco friendly drives employ 30nm class MLC NAND flash chips with a Toggle ddr interface, pictured, and a controller that uses a 3Gb/s SATA interface. According to Samsung, the performance matches, and in some cases even exceeds, some of the SLC NAND based SSDs now in the marketplace.
The drives have been designed to process random read commands at 43,000 input/outputs per second (IOPS) and random writes at 11,000 IOPS, in comparison to a 15K RPM 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.
In terms of power consumption, the SSDs are said to have a 150 times higher IOPS/Watt rate compared to 15K RPM HDDs, making them able to process 150 times more data while consuming the same amount of energy.
