Samsung Electronics has developed a 2.5-inch, 256GByte multi-level cell (MLC) based solid-state drive (SSD) using a SATA II interface. Apart from being the fastest, Samsung asserts that the new 256GByte SSD is also the thinnest drive with the largest capacity to be offered with a SATA II interface.

With a sequential read speed of 200Mbps and sequential write speed of 160Mbps, the MLC-based SSD is about 2.4 times faster than a typical HDD, says Samsung. Furthermore, the new drive is only 9.5mm thick, and measures 100.3mm x 69.85mm.

"With development of the 256GByte SSD, the notebook PC is on the brink of a second stage of evolution. This change is comparable to the evolution from the Sony Walkman to NAND memory-based MP3 players, representing an initial step in the shift to thinner, smaller SSD-based notebooks with significantly improved performance and more than ample storage," said Jim Elliott, VP, memory marketing, Samsung Semiconductor, Inc.

Through advancements in proprietary controller technology, the new drive features mean time between failures (MTBF) of 1 million hours, while costing considerably less, according to Samsung. Power consumption is also low at 0.9W in active mode. The drive also offers a data encryption process that prevents data stored on the SSD from being accessed in an unauthorized manner, even after the SSD is removed from the PC.

Samsung expects to begin mass-producing the 2.5-inch, 256Gbyte SSD by yearend, with customer samples available in September. A 1.8-inch version of the 256Gbyte SSD is expected to be available in Q4.
