Three years ago, I wrote a story comparing hard disk drives to solid state drives (SSDs) based on capacity, performance and cost.
A lot has changed in three years. For one, laptops are quickly being eclipsed by tablets, which have NAND flash memory embedded on their motherboards. In addition, operating systems like Windows 7 have been optimized to take advantage of SSD I/O performance.
SSDs today are far more reliable, have greater endurance and perform better (in some cases, two to three times better) than in 2009.
