HGST's New 1TB HDD Is 7mm Thin
HGST, a Western Digital company, launched the new 2.5-inch, 1TB, Travelstar Z5K1000 drive ? a 7.0 mm 5,400 RPM HDD with shock robustness for thin, ultra-portable devices.
The company also says it has shipped more than 100 million Travelstar Z-series, 7.0-millimeter (mm), 2.5-inch hard disk drives (HDD).
HGST's 7.0 mm Z-series HDD family features common connectors and mounting points for easy integration into existing systems.
With 1TB of capacity in a true 7.0mm format, a 6Gb/s SATA interface, a 3.0 second boot time, as well as a 32MB cache, the rugged, low-power Travelstar Z5K1000 mobile HDD offers manufacturers the features required to design new, thinner systems. With its 26 percent slimmer z-height compared to traditional 9.5mm 2.-5-inch drives, and weight of only 95 grams, OEMs and integrators have an opportunity to differentiate product lines by utilizing space savings to produce thinner, lighter devices, add battery capacity, increase shock robustness, or improve internal airflow.
Based on a two-disk 7.0 mm design, the new Travelstar Z5K1000 family features 1.6 watts (W) read/write power and 0.5W low-power idle, and delivers a nearly silent operation at 2.1 idle/2.2 seek bels. It also offers a high operating shock at 400G/2ms and non-operating shock at 1000G/1ms to protect against bumps and rough handling in mobile environments. A dual stage actuator is included for track miss registration improvements for greater data integrity and reliability, as well as Advanced Format to improve drive capacity and error correction capabilities of the drive.
Travelstar Z5K1000 is the seventh generation self-encrypting drive (SED) to feature HGST's Bulk Data Encryption. Designed to the Opal specification established by the Trusted Computing Group (TCG), the SED encrypts data using protected keys in real time. It also speeds and simplifies drive re-purposing. By deleting the encryption key, the data on the drive is rendered unreadable, thereby eliminating the need for time-consuming data-overwrite.
The Travelstar Z5K1000 family comes in 1TB and 750GB capacities.
According to IHS , the demand for thin HDDs is predicted to reach 140 million units by 2017, due to the increasing demand for ultra-thin PCs and tablets.
