HGST, formerly Hitachi Global Storage Technologies and now a subsidiary of Western Digital (WD), is bringing its new Travelstar 5K1500 to the market. The 5K1500 offers an impressive capacity of 1.5TB while maintaining a notebook-standard height of 9.5 millimeters. As a reminder, thicker 2.5-inch drives are either 15mm or 12.5mm, while Ultrabooks and Hybrid computers predominantly use 7mm drives.
Hitachi (or rather HGST) manages to achieve its 1.5TB milestone by fitting three 500GB platters in a space that has so far only incorporated two platters (as far as 9.5mm drives are concerned). The 5K1500 spins at a conservative 5400 RPM, however the company is keen to point out a ‘best-of-breed’ media transfer rate of 998Mb/s in PCMark 7 and PCMark Vantage testing.
Other specifications include a 32MB cache buffer and 6Gbps SATA interface, while the halogen-free components of the Travelstar 5K1500 are designed to withstand operating shocks of up to 400G and 1000G non-operating shocks. Operating power is 1.8W when the drive is in use and 0.5W at idle.
Besides notebooks the new drive is targeting external hard drives, gaming consoles, and all-in-one (AiO) desktop PCs. Pricing remains unknown for the time being however the Travelstar 5K1500 is expected to be available in June.
