Solid-state drives continue to outperform hard-disk drives in tests, providing some consolation for the high price.
The X300 ThinkPad, which starts at $2,900, is one of the hottest--and most expensive--notebooks on the market now. The Apple MacBook Air is another. They both come with solid-state drives (SSDs) that perform better than standard magnetic hard-disk drives. And the X300's outpaces a 7200rpm hard drive by a long shot, according to review site Hot Hardware.
