Samsung drives to produce more reliable SSDs

Samsung Electronics Co. Ltd has started volume production of its 1.8in and 2.5in multilevel cell (MLC)-based solid-state drives (SSD) with a 128Gbyte storage capacity.

Mass production of the Samsung MLC-based 64Gbyte SSD also began this month.

The Korean chipmaker said it plans to begin producing a 256Gbyte version at the end of this year, and that it expects sales of SSD units to increase 800 percent between now and 2010, making this category the largest growth segment in the NAND flash market over the next few years.

Mass production of the 128Gbyte SSDs should help Samsung maintain its position as the leading producer of SSDs, with capacities ranging from 32Gbyte.

The parts are said to feature far greater reliability, faster boot times and faster application start-up times than hard disk drives. Power consumption is claimed to be exceptionally low in standby mode at approximately 0.2W and in active mode at 0.5W.

The MLC-based SSD has a write speed of 70Mbyte/s and a read speed of 90Mbyte/s performance levels that approach those of single-level-cell (SLC)-based SSDs now in mass production. Samsung added that the 128Gbyte version will last approximately 20 times longer than the generally accepted four-to-five-year lifespan of a notebook PC hard drive.

Featuring a 3.0Gbit/s interface, the 128Gbyte MLC-based drive integrates 64 MLC NAND flash memory chips of 16Gbit each, optimized single-chip controller technology and advanced flash-management firmware technology.
