Seagate, Samsung and Toshiba recently introducing versions of their own. Western Digital's iteration -- the Scorpio Blue 640 -- sports a luscious standard 9.5mm-height package, which should fit just fine within pretty much any laptop out there. WD also claims that this HDD consumes some 30 percent less power than the previous generation Scorpio Blue, though the 5400RPM spindle speed certainly won't impress the performance junkies in the crowd. Look for it to slide into your next portable for $149.
