Well look at that: it’s the world’s first 320GB hard disk drive to spin at 7,200 RPM in a 7-mm high package — take that Seagate. The 2.5-inch Serial ATA 3Gbps Travelstar Z7K320 features a 1,334Mbps max transfer rate assisted by a 16MB cache. The HDD draws 1.8 watts during read/write operations and 0.8 watts on lower-power idle while humming along at 23dB when idle or 24dB when seeking. And that skinny 7-mm form factor means it’ll go places no standard 9.5-mm thick drive could even dream of when it hits the mass production lines in August — like say next generation ultra-thin netbooks.
