Samsung Electronics announced today the world's fastest, 2.5", 256GB multi-level cell (MLC) based solid state drive (SSD) using a SATA II interface.

The new Samsung 256GB SSD is also the thinnest drive with the largest capacity to be offered with a SATA II interface.
Performance data of the new Samsung 256GB SSD features a sequential read speed of 200 megabytes per second (MB/s) and sequential write speed of 160MB/s. The Samsung MLC-based 2.5-inch 256GB SSD is about 2.4 times faster than a typical HDD. Furthermore, the new 256 GB SSD is only 9.5 millimeters (mm) thick, and measures 100.3x69.85 mm.

Samsung’s new MLC 256GB SSD, besides being comparable in speed to an SLC-based SSD, also boasts reliability equal to that of SLC SSDs, with a mean time between failures (MTBF) of one million hours, while costing considerably less. Power consumption is also exceptionally low at 0.9 watts in active mode.
Samsung is expected to begin mass producing the 2.5-inch, 256GB SSD by year end, with customer samples available in September. A 1.8-inch version of the 256GB SSD is expected to be available in the fourth quarter of 2008.

According to a Q1 2008 report by the semiconductor market research firm iSuppli, the SSD market will grow at an annualized average of 124 percent during the four-year period from 2008 until 2012. iSuppli now projects SSD sales to increase by an additional 35 percent in 2009 over what it projected last year, 51 percent more in 2010, and 89 percent more in 2011, and continue to show dramatic increases in subsequent years.
