Toshiba Corporation has announced two new lineups (MK-GSX and MK-GSY) of hard disk drives for mobile or portable applications that offer either increased capacities or leading performance. Both families of HDDs support an optional Free Fall Sensor function, which detects falling HDD and parks the head before it crashes. Toshiba did not reveal when the new drives are planned to be commercially available.
The flagship Toshiba MK3252GSX model has two 160GB platters, for a total capacity of 320GB. The new hard drive features Serial ATA-300 interface, 5400rpm motor, 8MB buffer and 12ms average seek time. Other members of Toshiba MK-GSX family sport similar technical characteristics, but feature capacities of 250GB, 160GB, 120GB or 80GB. The Toshiba MK2049GSY uses two 100GB platters for a capacity of 200GB. The two main advantages of the HDD are 7200rpm motor and a 16MB buffer. Toshiba declares that the new drive increases the maximum transfer rate by approximately 46% and the average random access time by approximately 8% when compared to the current MK1637GSX model. Other new members of the family feature capacities of 160GB, 120GB or 80GB.
