We've been testing and reviewing storage drives in various categories over the past few years. Now, laptops are slowly but surely becoming a mainstream product, tentatively poised to replace desktops, and we had to ask ourselves: why not review a laptop hard drive? So today, we've decided to test one of those -- a laptop hard drive belongs in a class of storage media that has been around for long, and that has been gaining importance of late. Luckily, we happened to chance upon the largest 2.5-inch hard drive available in the market -- Western Digital's Scorpio WD3200BEVT, which has a huge capacity of 320 GB.
