Modern NVMe SSD (2 TB)

Five hundred million times denser than the first hard drive/Computing

A modern M.2 NVMe solid-state drive stores 2 terabytes in a stick smaller than a pack of gum. It has no moving parts, reads data at over 7 GB/s, and weighs about 9 grams. The IBM 350 stored 3.75 MB in a ton of machinery. This little stick stores 500,000 times more in a space you could lose between couch cushions.
