The latest contender on the 500GB mobile hard-drive stage is now shipping, Western Digital has announced. The new WD Scorpio Blue 500GB hard drive has a 2.5" form factor, 5,400-RPM platter speed, 300MB/s Serial ATA interface, 8MB buffer, and—most importantly—only two platters. Each platter in the Scorpio Blue packs a surprisingly dense 250GB, which could give Western Digital an edge over its competitors with potentially louder and power-hungrier three-platter 500GB drives.
WD rates the Scorpio Blue for 24-26dB noise levels, 12-ms read seek times, and 2.5W power dissipation during reads and writes. The drive reportedly includes "proprietary features that make [it] extraordinarily quiet, while running at cool operating temperatures," too.
The 500GB Scorpio Blue is currently shipping through "select distributors and resellers," with a suggested retail price of $219.99. WD also has a 400GB Scorpio Blue model based on the same platters, and that particular offering has a $189.99 suggested retail price. Both models come with three-year warranties.
