The first one-gigabyte hard drive, produced in 1980, was rather pricey. The IBM 3380 HDA cost $40 000 R400 000.00) and weighed over 225kg.
One Gigabyte hard drives are around R1000.00 today – That is equal to 0,0025% of the price in 1980.
So – if you hang around for another 35 years then maybe the price of a one gigabyte drive will be R2.50
The 3380 series was a storage solution to be use alongside a computer (it was not a computer in itself). Each unit of the early models of the 3380 series (A4, A4F, AA4, AAF, B4 and BF4) was composed of two of those hard drives (or two HDAs). Each of them had a capacity of about 1.26GB, providing one storage device of the 3380 series with a total capacity 2.52GB.
Tested returns to Adam’s workshop to geek out about his collection of arcane computer technology. Adam shows off an old IBM bit, byte, and even a massive one gigabyte hard drive from 1981 – which weighs 75 pounds.
History of the Hard Drive up to 1980:
1956: IBM ships the first hard drive in the RAMAC 305 system. The drive holds 5MB of data at $10,000 a megabyte. The system is as big as two refrigerators and uses 50 24-inch platters.
1961: IBM invents heads for disk drives that “fly” on a cushion of air or on “air bearings.”
1963: IBM comes up with the first removable hard drive, the 1311, which has six 14-inch platters and holds 2.6MB.
1966: IBM introduces the first drive using a wound-coil ferrite recording head.
1970: General Digital Corporation (renamed Western Digital in 1971) is founded in California.
1973: IBM announces the 3340, the first modern “Winchester” hard drive, which has a sealed assembly, lubricated spindles, and low-mass heads.
1978: First RAID (Redundant Arrays of Independent Disks) technology patent is filed.
1979: A group headed by Al Shugart founds disk-drive manufacturer Seagate Technology.
1979: IBM’s 3370 uses seven 14-inch platters to store 571MB, the first drive to use thin-film heads.
1979: IBM’s 62 PC, “Piccolo,” uses six 8-inch platters to store 64MB.
1979: Seagate introduces the ST-506 drive and interface, which is then used in all early microcomputer implementations.
1980: IBM introduces the first gigabyte hard drive. It is the size of a refrigerator, weighs about 550 pounds, and costs $40,000.
1980: Seagate releases the first 5.25-inch hard disk.
