Fujitsu's 2.5-inch 320GB drive does 7,200rpm

The company claims it's the world's first 2.5-inch drive to meet those specifications.

Bigger, faster, thinner is the name of the game in hard drives.

Fujitsu is only the latest drive maker to use superlative adjectives to market its newest product. In this case it's the MHZ2 BJ series of its 2.5-inch hard disk drives, which the company claimed Monday is the "world's first" 320GB drive that rotates at speeds of 7,200 revolutions per minute.

That claim can be a tad misleading since there are drives out there that do the same spin speed, though they're smaller in size. Plus there are higher capacity drives already announced and on the market. Heck, Fujitsu has bigger hard drives--the 500GB 2.5-inch drive announced last month is bigger (half a terabyte!), but spins (reads and writes data) at 4,200rpm. So "world's first" really refers to that specific combination of features.

The 2.5-inch drive is meant for higher-end notebooks and even compact desktops, Fujitsu says. It uses a Serial ATA 3.0 gigabits-per-second interface, which enables high-speed data transfers from the drive to the PC. And on the green front, this Fujitsu drive needs only 2.3 watts of power while it's reading and writing data.

The drives will be available to Fujitsu's customers starting in June.
