Toshiba Corporation today announced a new line-up of 1.8-inch hard disk drives (HDD) adopting a serial ATA interface, including the industry’s first(1) drive of this type with a capacity of 160 gigabytes. The new 160GB drive, MK1617GSG, and an 80GB drive, MK8017GSG, will enter mass production in August.
Both the 160GB MK1617GSG and 80GB MK8017GSG drives measure 54 x 78.5 x 8 mm, have SATA 1.5 Gbps interfaces and work at 5400 rpm. Kim said the single platter 80GB drive replaces Toshiba’s two-platter 80GB MK8016GSG 1.8-in. drive that was unveiled in February. Toshiba upped the areal density on its single-platter 80GB drive to 246.8 gigabits per square inch, compared to the older model’s 182.8 gigabits per square inch.
The new MK1617GSG drive is more environmentally efficient than Toshiba’s current MK1216GSG (120GB) model, and raises energy consumption efficiency, as defined under the Japanese legal standard, to 0.00281W/GB, a 25% improvement. The drive improves the maximum internal data transfer rate by approximately 17%, and supports faster data access in reading and writing that enhances overall performance.
Combined with the new micro-SATA connector, Serial-ATA 1.5Gb/s interface and 5,400 RPM spin speed, the MKxx17GSG series offers small and light-weight solutions at increased data transfer rates for enhanced performance in sub-notebook PCs.
