Before the early 1980s, most HDDs had 8-inch (20 cm) or 14-inch (35 cm) platters, required an equipment rack or a large amount of floor space (especially the large removable-media disks, which were often referred to as “washing machines”), and in many cases needed high-current or even three-phase power hookups due to the large motors they used.

In above pic, to your left is a hard drive from IBM with a total capacity of 1GB. To your right is an SD card whose capacity is equal to that of the IBM drive.

It’s amazing the difference 20 years of advancement can make, isn’t it?
