I know the general consensus is that the Samsung SSD in the Air is faster than the Toshiba one. These benchmarks reach different conclusions. In 4 out of 5 benchmarks the Kingston V+ 100 beats the Samsung 470. all 4 of them are real world benchmarks. In real life it's unlikely you'll notice any difference though. Kingston V+ 100 uses the exact same Toshiba controller and performs nearly identical to the Toshiba SSD Apple uses in the Air. Samsung 470 is virtually the same as the Samsung SSD.
