(formerly Hitachi Global Storage Technologies and now a wholly owned subsidiary of Western Digital
) claims that its latest mobile hard drive
, the Travelstar 5K1500, offers the--and we quote--“highest storage density of any hard disk drive today”.
Those are strong words, but HGST may have something there. They crammed 1.5TB into a 2.5-inch, 9.5mm chassis that houses three platters. The drives also feature 32MB cache and a 6Gbps SATA
interface with 5400 RPM speed.
At idle, the Travelstar 5K1500 consumes just 0.5W of power and emits 2.5 bels, making it both power efficient and very quiet--both of which are features that mobile system makers cherish. Further, to protect against the beating mobile drives usually take, the HDD has a dual stage actuator and features 400G/2ms and 1000G/1ms operating and non-operating shock, respectively.
The Travelstar 5K1500 is a mainstream device, but HGST says that the drive will also come in an Enhanced Availability (EA) model designed for applications including blade servers, network routers, video surveillance, and more.
The hard drive will ship in June, with the EA version hitting the market sometime in Q3 of this year.
