TOKYO– Toshiba Corporation (TOKYO: 6502), the pioneer in small form factor hard disk drives (HDDs),  today announced a new family of high-performance 7,200RPM 2.5-inch HDDs, including a top-end drive with a half-terabyte capacity. Mass production of the series will start in October.
  Toshiba's high-performance MK5056GSYseries offers capacities of 160GB, 250GB, 320GB and 500GB for commercial and consumer notebook PCs, gaming notebooks, and tiny and all-in-one desktops. In operation, the drives deliver significant performance improvements over Toshiba's previous generation of 7,200RPM drives. Data is transferred at 1,255Mb/s, a 23% boost, and energy consumption efficiency is raised by 28%.
  Application of Toshiba's original advanced acoustic management technology in the new double-platter MK5056GSY, the leading edge half-terabyte model, and the MK3256GSY, cuts acoustic noise during seek to 25dB, a 3dB decrease from the earlier MK3254GSY. The single-platter models, MK2556GSY and MK1656GSY, cut acoustic noise to 23dB, a 2dB decrease from the MK1654GSY, until now the quietest 7,200RPM 2.5-inch HDD. The MK5056GSY family is also compliant with the European Union's RoHS directive and halogen free.

Key Features

1. Reaches industry's largest capacity in 7200RPM model (MK5056GSY)

Toshiba's improved magnetic head and disk layer technology realize an areal density of 612 Mbit/mm2 (395 Gbit/in2) for the MK5056GSY, matching the industry highest level for 7,200RPM disks. Four different capacities are offered, in order to precisely meet customer demand.

2. Improved energy consumption efficiency (MK5056GSY)
Compared to Toshiba's previous highest capacity HDD (the 320GB MK3254GSY), the new 500GB HDD MK5056GSY offers a 28% improvement in energy efficiency, as defined under the Japanese legal standard.
3. Environmentally Conscious products

(1) RoHS compliant
The new drives comply with the European Union's RoHS directive[1] for eliminating use of six hazardous substances in electrical and electronic equipment.

(2) The new series meets standards for certification as a standout Toshiba ECP

One Gigabyte (1 GB) means 109 =1,000,000,000 bytes using powers of 10. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1 GB = 230= 1,073,741,824 bytes, and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system. Examples of the number of photos, songs, movies, and any other files that can be stored on a hard drive are provided for illustrative purposes only. Your results will vary based on file size and format, settings, features, operating system, software and other factors.
