kingspec 1.8" ssd
SSD in my circa 2005 IBM ThinkPad X40 (1.4ghz, 1.5gb RAM, formerly 40gb Hitachi 4200rpm 1.8" HD).
Replacement drive is a 64gb KingSpec 1.8" SSD. CrystalDiskMark says it crushes the abysmally slow Hitachi 4200rpm drive ;] Go figure.
For more SSD goodness, take a look here - Intel X25-M G2 SSD =]
