Solid State Drives Are Fast, Reliable, and Very Difficult to Securely Erase

Solid State Drives (SSD) use solid-state memory instead of spinning disc platters (as in hard disk drives) to store large ammounts of data. SSD prices have been dropping while storage capacities have been increasing in the past few years. SSDs can provide greater realiability and access speed at a higher cost per byte. Perhaps the best known SSD device is Apple’s MacBook Air.
