Hitachi hard drive goes perpendicular

The most reliable drive of its type?

Hitachi has released a laptop hard drive using perpendicular recording technology. The Travelstar 5K160, like Seagate's Momentus 5400, spins at 5400rpm and has a 160GB capacity. Hitachi claims the drive is the most reliable of its type.

The 5K160 follows on from the existing Travelstar 5K100, which uses traditional longitudinal recording technology to offer 100GB. PMR (perpendicular magnetic recording) has delivered a 60 percent capacity boost.

Seagate has already expanded its PMR range to include a 750GB Barracuda.

Hitachi says it will extend the PMR technology across its hard drive range. A 1.8in drive is expected shortly. This could provide 100GB capacity, up from the current 1.8in C4K60's 60GB, with lower power consumption because of slower spin-speed of 3600rpm, down from 4200rpm. It should have a 20 percent improvement in read/write power consumption and the fastest power-on-to-ready time for immediacy of data delivery.
