Toshiba today announced its new 2.5-inch MQ04 Series 2TB HDD model MQ04ABD200, designed for use in notebook PCs, all-in-one and slim-line desktop systems.

The MQ04ABD200 dual-disk model delivers 2TB of storage capacity in a 2.5-inch, 9.5mm height form factor. The drive's 6Gbit/s SATA interface and 5,400rpm performance, combined with a large 128MiB buffer, result in a 34 percent increase in maximum transfer rates and a 50 percent improvement in power efficiency compared to Toshiba's previous 1TB mobile-class model generation, MQ01ABD100.

The MQ04 2TB model has a Mean Time to Failure (MTTF) of 600,000 h and it is currently available.
