WD ships dual-platter 500GB mobile drive
 

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.
