HGST, which is now owned by Western Digital, has added a new model to its Travelstar family. The 5K1500, a 9.5mm model, is the first on the market to come with a 1.5TB capacity, which is 50 per cent more than the biggest hard drives on the market.
The drive is aimed at the growing market of external hard disk drives, high end laptops, all in one PCs and rack-mounted servers. HGST achieved this capacity by using three 500GB platters, a feat that has only been achieved by using some clever engineering in order to avoid issues related to shock (as the platters are much closer).
The drive adopted a 9.5mm form factor rather than a 7mm one which means that it might not fit some slim-and-light devices on the market. As for the rest of its specifications, HGST claims that the 5K1500 consumes a mere 500mW when idle, with a 5,400RPM spinning speed, 32GB cache and a 6Gbps SATA interface.
The price of that drive has yet to be announced but the model should ship in June with an EA model destined at systems where data is accessed constantly, will ship in the third quarter of the year. A 1TB external 2.5in hard disk drive currently ships for around £50 in the UK which means that the 1.5TB 9.5mm model should retail for around £100.
