Hard drives continued to become smaller with the launch of the Integra Peripherals 1.8-inch disk in 1991 and the HP Kittyhawk 1.3-inch hard drive in 1992. 1986 saw the introduction of the SCSI interface standard, which was used by Apples Mac Plus computer. It had a 20MB capacity on two disk platters. In 1964, Burroughs introduced the B-475 disk drive, with a head per track, as part of the B5500. Capacity of hard drives continued to increase towards the end of the decade, with the first 3TB hard drives to be released by Seagate and Western Digital in 2010. Since they were so large, we divided them into four partitions, each of which we regarded as a separate hardware device -- analogous to a cassette drive (our other main peripheral storage device). The term later referred to all fixed hard disks because the heads and platters are always encased in the same, sealed unit. The nickname "floppy" came from the disk's flexibility.
