Toshiba has expanded line-up of NAND-flash-based solid state drives (SSDs) based on the company’s 32nm multi-level-cell NAND flash memories. The new drives include 128-gigabyte Half-Slim/mSATA SG series SSD modules for applications including mini-mobile and netbook PCs, and the HG Series that offers performance essential for notebook computers and for gaming and home entertainment systems.
According to Toshiba, the SSD Series introduces 128GB mSATA and Half-Slim modules, with a maximum sequential read speed of 180MBps and a maximum sequential write speed of 70MBps. The 128GB modules are one seventh the volume and one eighth the weight of 2.5-inch form factor SSDs, and consume a fraction of the power.
Toshiba said that its 3rd-generation HG high performance SSDs come with MLC controller that supports maximum sequential read speed of 250MBps and maximum sequential write speed of 180MBps with faster boot and application loading times. They will be made available in 64GB, 128GB, 256GB and 512GB capacities in a standard 9.5mm (2.5-inch case), and in a special 7mm thin 2.5-inch case in 128GB and 256GB capacities.
In addition, smaller 1.8-inch drives are available in 64GB, 128GB and 256GB capacities in a standard 1.8-inch disk drive case or as caseless or LIF-modules. The drives also offer AES data encryption to support only authorised data access.
Both the new series support the TRIM command implemented in Windows 7, which enables the OS to tell the SSD controller that the data can be actually deleted, freeing the blocks for subsequent use and maintaining SSD performance, the company added.
