Those looking for a large SSD should head over to Rakuten.com (formerly Buy.com), where the 500GB Samsung 840 SSD is on sale for $259 after a $25 coupon, good through March 21, 2013. The 840 may not be as fast as its well-reviewed “Pro” sibling, but at $0.52 per gigabyte it’s a great price on a drive that will safely outperform a 2.5-inch hard drive. Newegg and Amazon have the drive currently priced at $370 and $330, respectively.
