Toshiba introduces 256 GB solid state disk drives

Toshiba has made available new flash memory based storage drives called X-gale SSD series in new slim form factor and in capacities of 64 -gigabyte (GB), 128GB and 256GB, with a maximum sequential read speed of 220MB per second (MB/s) and a maximum sequential write speed of 180MB/s. This series is suggested for portable applications such as tablet PCs, laptops, mini-mobile and netbook PCs .

"Delivering a product that enables superior user experience in a smaller footprint is the ultimate goal," noted Scott Nelson, vice president, Memory Business Unit, Toshiba America Electronic Components, Inc. "The density of MLC NAND enables the creation of smaller form factor high density storage solutions, and Toshiba, as the technology leader for NAND storage solutions, will continue to innovate in this space."

Toshiba says this new 64GB and 128GB Blade X-gale SSDs are the thinnest available within the company's comprehensive portfolio of SSD solutions. At a thickness of 2.2mm, the modules are 42 percent thinner than that of a typical mSATA SSD, and Toshiba's advanced wiring technology has assured optimized wiring layouts and data transfer rates in this new form factor.

"Until recently, storage designers looking for high capacity storage had accommodated the size of HDD into their designs," continued Nelson. "Up to this point, SSD designs also followed the basic design of small form factor HDD - which does not fully leverage the capabilities of high density NAND technology. Toshiba's module-based SSDs break with this approach, giving hardware designers greater freedom and flexibility in enabling their product design."
