Samsung Electronics Co. Ltd has begun mass-producing 256Gbyte solid state drives (SSDs) for use in notebooks and desktop PCs.

The 256Gbyte SSD more than doubles the performance rates of Samsung 64Gbyte and 128Gbyte SSDs. It delivers sequential read rates of 220Mbyte/s with sequential write rates of 200Mbyte/s. In addition, erase cycles are a rapid 100Gbyte/s per minute.

10x faster
The Samsung 256Gbyte SSD expedites data transfer when large multimedia files are simultaneously read and stored. It can store 25 high-definition movies in 21mins, an advancement over a 7,200rpm HDD, which takes about 70mins Furthermore, the 256Gbyte SSD launches applications 10 times faster than the fastest 7,200rpm notebook HDD.

The 256Gbyte SSD's design includes a chip controller, NAND flash and special drive firmware all developed by Samsung. This single platform is designed to easily adapt to Samsung's 40nm class NAND flash memory.

The drive consumes 1.1W of power vs. 2W or more for a comparable HDD. The high operating speed of the 256Gbyte SSD translates into longer periods in either stand-by or idle mode, resulting in up to 40mins of extended operation on a single battery charge.

Similar in weight to a 128Gbyte SSD (81g), the 2.5-inch multi-level cell (MLC) 256Gbyte SSD retains the standard 9.5mm drive thickness.

Samsung's 256Gbyte SSD is also available with optional proprietary encryption programming that provides full disk encryption, a key feature for many corporate users.
