The commercial usage of hard disk drives (HDD) began in 1957, with the shipment of a production IBM 305 RAMAC system including IBM Model 350 disk storage. The earliest drives were usable only in the protected environment of a data center. Later generations progressively reached factories, offices and homes, eventually becoming ubiquitous.
The 1980s saw the minicomputer age plateau as PCs were introduced. Manufacturers such as DEC and Hewlett-Packard continued to manufacture minicomputer compatible hard drive systems as industry demanded higher storage. However by the late '80s, hard disk drives were standard on all but the cheapest PC and floppy disks were used almost solely as transport media. HDDs continued to get smaller with the introduction of the 3.5-inch form factor in the middle of the decade with average size of 20 MB and SCSI attachment.
During 1990s even though there were a number of new entrants, industry participants continued to decline in total to 15 in 1999. The first version of what is now called the ATA/ATAPI interface was standardized in 1994 and common hard drives presented 340 MB storage and 5 MB transfer rate.
SATA was announced in 2000 in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing protocol.
The basis for flash-based SSDs, flash memory, was invented by in 1980, but common usage begun in the late 2010s.
