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.
