Hitachi Global Storage Technologies (HGST, which is now owned by Western Digital) has developed a new 2.5” mobile hard drive called the Travelstar 5K1500. The hard drive uses three 500GB platter drives for a total capacity of 1.5TB. HGST claims that the drive is the highest capacity 9.5mm mobile drive on the market. Additionally, the company has stated that the new drive is faster than its existing two-platter hard drives according to the PCMark Vantage and PCMark 7 benchmark suites.

The 1.5TB Travelstar 5K1500 is a 5400 RPM hard drive with 32MB of on-board cache, a 6Gbps SATA III interface, and shock protection features.

The new mobile drive will be used in external hard drives, all-in-one systems, and notebooks where storage space is valued more than pure performance. It will be available sometime in June for an as-yet-unannounced price point. Another version of the Travelstar 5K1500 that offers automatic encryption of data will be available in Q3 2013.
