1976
cassette tape
1972
one of the first mass produced consumer storage devices. used for saving document and even loading operating systems. It had 1.2mb of storage.
IBM 3380
1980
once used as an inexpensive way to save data it was slowly replaced as floppies became cheaper It had 660kb of storage.
The first device to reach the gigabyte realm reaching 2.52GB of storage.
MiniDisc MD Data
1993
IBM 350
1956
Sony intended the MD Data to replace the floppy disk as the consumer storage platform of choice, but it was too expensive and eventually out placed by the more popular zip disk. they have 140mb of storage
ST-506
1980
Uniservo
1951
This was the first 5.25" drive and the precursor to the modern PC HDD with 5mb.
The first "modern" hard drive with 24 disks that spun at 1200 RPM
4.4mb of storage
CD-R
1990
Zip
1994
This format is still widely used. its large storage capacity and low price helped it surpress the floppy disk and survive the rise of zap and jaz disks. the CD-R has 700mb of storage.
This was the essential storage device for large documents and graphic design files, it quickly replaced floppy discs and was favoured over CD-R's becasue they were rewritable. They have 100mb of storage.
Seagate Barracuda
1996
DAT
1987
This was the first 7200 RPM drive, a speed that became the standard we see in most modern disks today. They have 2.25 GB of storage.

it had 128 bits per inch
The format was going to be a high end music recording device but later became a storage device for computers. They have 1.3GB of storage.
Drum memory
1950
IBM 170 microdrive

Solid-State Drive
2008
Cloud Storage
NOW
With no moving parts, faster boot times and less physical space, they are now the new way we store digital media. They have 64GB or storage.
With online services customers can access nearly limitless storage from any internet connected device.
