HGST, a subsidiary of Western Digital Corp., has introduced Travelstar Z5K1000 drive, the company’s first 7mm hard disk drive featuring 1TB capacity. The new HDD features best-in-class shock robustness for thin, ultra-portable laptops, ultrabooks, external storage and ultra-compact CE devices. Separately, the company announced that it has shipped more than 100 million Travelstar Z-series HDDs.

“The 7.0 mm 2.5” mobile market continues to be a strategic space for HGST as evidenced by our record 100M shipments. With the addition of our new 1TB Travelstar Z5K1000, HGST continues to offer the market’s broadest 5400 and 7200 RPM 7.0 mm 2.5-inch hard drive portfolio to meet the needs of a diverse mobile computing and storage segment,” said Brendan Collins, vice president of product marketing at HGST.

HGST’s Travelstar Z5K1000 hard disk drive comes in 2.5”/7mm form-factor and features 5400rpm spindle speed, 32MB cache and Serial ATA-6Gb/s interface. Thanks to two platters, the drive features 1TB capacity and is currently among the first 7mm hard drives in the industry to offer such amount of storage space. Based on a unique, compact, two-disk 7.0 mm design, the new Travelstar Z5K1000 family features 1.6W 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 the industry’s highest 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.

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. The expanded HGST 7.0 mm Z-series will help feed this demand. With 1TB of capacity in a true 7.0mm format, an industry-first SATA-6Gb/s interface, an ultrafast 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% 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.

“Hard drives will remain the mass storage vehicle of choice, having the best cost-per-GB ratio of any storage medium on the market. Also, as consumers create and consume more and more digital content, the need for additional storage becomes essential. Because of this, 7mm HDDs, especially HGST’s 1TB Travelstar Z5K1000, will continue to play a major role in the thin and light device segment moving forward,” said Fang Zhang, analyst, storage systems at IHS.   

Travelstar Z5K1000 is the seventh generation self-encrypting drive (SED) to feature HGST’s Bulk Data Encryption. HGST’s hard drive-based encryption is a highly attractive option for any company routinely carrying sensitive information on laptops or portable storage devices. Designed to the Opal specification established by the Trusted Computing Group (TCG), the SED encrypts data using protected keys in real time, providing users with the highest level of data protection available. 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. HGST is currently qualifying its Travelstar Z5K1000 with select OEMs. Broader qualification samples are now available with channel distribution scheduled in November.
