HGST Travelstar 5K1500 Notebook Drive: 1.5TB in Slim 9.5mm Casing
Starting sometime next month, the company formerly known as Hitachi GST will begin shipping a 2.5” hard drive with a 1.5TB (1500GB) total capacity. While 2.5” drives of that capacity have already been available for a little while now, the Travelstar 5K1500 differs in that it is a slimmer 9.5mm-height design (as opposed to 12.5mm or 15mm), allowing it to be installed into the majority of laptop computers and external enclosures out there.
In an interesting twist, HGST did not achieve the storage landmark in the 2.5” 9.5mm-thick size by bumping up platter density, but by shoehorning three of the current-generation 500GB platters into the space normally taken up by two. Despite this, HGST claims the Travelstar 5K1500 is just as physical-shock-tolerant as the firm's own “normal” 9.5mm units – at a rated 400 and 1000 Gs of operating and non-operating shock, respectively – and other general specifications seem to have been not compromised, as well.
Those specs, to be exact, include a 5400 RPM rotational speed, a 32MB cache, and a SATA 6Gbps interface. HGST specifies 0.5w idle power and 1.8w maximum read/write power – both good in the face of Dual Stage Actuator technology, which provides increased resilience to vibration-prone environments, and the aforementioned three-platter, six-head design. As usual for HGST, versions of this Travelstar primed for 24/7 constant use (dubbed “Enhanced Availability”) and capable of self-encryption will also be available.
As mentioned in the beginning of this article, HGST will begin rolling out Travelstar 5K1500s en masse to retailers and PC makers sometime next month.
