Seoul, KoreaSamsung Electronics Co. Ltd. has begun mass producing 256 gigabyte (GB) solid state drives for use in notebooks and desktop PCs.
The 256GB SSD more than doubles the performance rates of Samsung 64GB and 128GB SSDs. It delivers sequential read rates of 220MB/s (megabytes per second) with sequential write rates of 200MB/s. In addition, erase cycles are a rapid 100GBs per minute.
The Samsung 256GB SSD expedites data transfer when large multimedia files are simultaneously read and stored. It can store 25 high-definition movies in 21 minutes, an advancement over a 7200rpm hard disk drive (HDD), which takes about 70 minutes. Furthermore, the 256GB SSD launches applications 10 times faster than the fastest 7200rpm notebook HDD.
The 256GB 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 1.1 watts of power versus two or more watts for a comparable HDD. The high operating speed of the 256GB SSD translates into longer periods in either stand-by or idle mode resulting in up to 40 minutes of extended operation on a single battery charge.
Similar in weight to a 128GB SSD (81 grams), the 2.5-inch multi-level cell (MLC) 256GB SSD retains the standard 9.5 millimeter (mm) drive thickness.
Samsung's 256GB SSD is also available with optional proprietary encryption programming that provides full disk encryption, a key feature for many corporate users.
