Little, big, and green: a biography of the solid-state disk

Faster and dramatically more power-efficient than rotating magnetic media, solid-state disks (SSDs) are one of the longest-awaited and most eagerly anticipated technologies in the past two decades of computing. The theoretical underpinnings of mass storage with no moving parts have been with us for decades, but the improvements that have put solid-state in economic and technological reach of ever larger segments of the storage market have been slow in coming.
