JAPANESE HARDWARE MAKER Toshiba has announced its Q series of solid-state disk (SSD) drives with capacities ranging from 128GB to 512GB.
Toshiba is the only hard drive maker to have fully embraced SSDs, perhaps due to its presence in the NAND flash market. Now the firm has extended its SSD range with 128GB, 256GB ND 512GB models.
Toshiba's Q series SSDs use 19nm multi-level cell NAND chips and the SATA 3 interface. The firm cites ATTO benchmark figures for its range topping 512GB SSD model at 552MB/sec and 501MB/sec for reading and writing, respectively, with 90,000 IOPS read and 35,000 IOPS write.
Toshiba is pitching its Q series SSD drives as upgrades for laptop users that are still using 2.5in hard drives. With more laptops having SSD drives, especially those that bear Intel's ultrabook branding, for many laptops an SSD is perhaps the best upgrade a user can buy.
Although Toshiba has only three Q series SSD models, the firm is the only traditional hard drive maker to have wholeheartedly entered the SSD market. Toshiba's HDD division got a major boost two years ago when Western Digital was forced to sell part of its hard drive business to Toshiba in order to please regulators and get its purchase of Hitachi's hard drive business approved.
Toshiba's Q series SSDs are expected to appear on retail shelves in the coming weeks, although there are no exact details available just yet. µ
