Toshiba will expand its family of small form factor 2.5-inch HDDs with a new series that packs up to 500GB of data storage into a unit with a height of just 7mm. The new "MQ01ACF" series will start shipping from August 30.
The "MQ01ACF" series is Toshiba's first 7,278rpm, 2.5-inch product with a 7mm height. The series offers two models: the "MQ01ACF050" with a recording capacity of 500GB and the 320GB "MQ01ACF032". The disks achieve a maximum internal transfer rate of 1,850Mbit/s due to their improved linear recording density and their fast 7,278rpm rotational speed. Implementation of the 6Gbit/s SATA interface also boosts data transfer rates over those of current models.
The slim "MQ01ACF" series has been designed for laptops and ultra-thin notebooks.
