Toshiba is proving that size isn’t all that matters, especially in the notebook world.
The Japanese manufacturer this week revealed a 2.5-inch hard drive disk capable of 15000RPM (revolutions per minute). While high-speed drives have existed in the past, this particular release will have a relatively high capacity of 300GB. Typical notebook drives spin about 2 to 3 times slower at 7200RPM or 5400RPM, depending on specs. The faster motor in the Toshiba hard drives allows for an average latency of about 2ms with average seek times of 3ms read and 2.7ms write.
Four initial models will be made available, the MK1401GRRB, MK1401GRRR, MK3001GRRB and MK3001GRRR. The two “3001” models will have a drive capacity of 300GB while the “1401” models are at half with only 147GB. Meanwhile, the models ending with “R” will include self-encrypting hardware designed to meet the TCG “Enterprise SSC” standards for additional security. Otherwise, all models have a 32MB buffer size and will be compatible with a 6GB/s SAS interface.
The 2.5-inch drives are scheduled to be available for enterprise users by the end of the year. Prices have yet to be announced, but a 5-year warranty will be included with each purchase. Check out the source PDF for more hardware details on the drives.
