"Memory" refers to random access memory (RAM), "disk" to magnetic storage, "flash" to special memory used for rapid data access and rewriting, and "solid state" to solid-state drives (SSDs). This data is expressed in US dollars per terabyte (TB), adjusted for inflation.

The floppy drives are not the lowest price per capacity. Floppies are included because they set a low unit price, making disk drives accessible to the masses. He also did solid state drives (since 2003), RAM (since 1957), and the cost of CPU performance (since 1944).

Here's a breakdown on the lifespan and cost per gigabyte of popular data storage types - from optical media to the cloud and more: Many professionals always keep at least three different backups of their data so that secure copies exist on multiple devices - but what data storage should you choose?

A floppy disk or floppy diskette (casually referred to as a floppy, a diskette, or a disk) is a type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk.

The floppy drives are not the lowest price per capacity. Floppies are included because they set a new new unit price, making disk drives accessible to the masses. Flash memory and solid state drives (SSD) are listed in another table.
