Toshiba Corp. has enhanced its line up of NAND-flash-based solid-state drives (SSD) with the addition of a 256Gbyte SSD and the launch of small-sized flash modules for netbook computers, ultramobile PCs (UMPCs) and other mobile and peripheral applications.

The company also added small size 8Gbyte, 16Gbyte and 32Gbyte flash modules for netbooks to the enhanced lineup.

The new drives will be showcased this week at CEATEC in Makuhari, Japan (Sept. 30 to Oct. 4).

Toshiba's high density SSD brings 256Gbyte of capacity to a 2.5-inch drive form factor with an advanced Multi-level Cell (MLC) controller that achieves higher read-write speeds, parallel data transfers and wear-leveling to optimize performance, reliability and endurance. Alongside this, Toshiba provides support for the growing market for small, netbook computers, UMPCs and other personal equipment with the launch of small SSD flash modules supporting 8Gbyte, 16Gbyte and 32Gbyte densities.

The 256Gbyte SSD mounts NAND flash memory on a 70.6mm (L) x 53.6mm (W) x 3.0mm (H) platform. The drive offers performance characteristics essential for today's mainstream notebook PCs: highly reliable, high density data storage and support for fast data transfer rates, with a maximum read speed of 120Mbps and maximum write speed of 70Mbps, via a SATA 3.0Gbps interface.

Flash modules are fabricated on a 50mm x 30mm platform, and offer maximum read and write speeds of 80Mbps and 50Mbps, respectively. Flash modules are also compatible with the SATA interface and will support continued development of the fast growing market for netbook PCs, UMPCs and mobile and peripheral applications by offering developers a wider range of SSD for integration in differentiated products.

Samples of the 256Gbyte SSD sell for $946, $47 for the 8Gbyte flash module, $95 for the 16Gbyte flash module, and $189 for the 32Gbyte flash module. Mass-produced units are expected in Q4.
