It held 5MB of data, at a cost of $10,000 per megabyte. Computer data was written to and read from the disk's surface. The IBM3340 hard disk drive (HDD) that began shipping in November 1973 pioneered new low-cost, low-load, landing read/write heads with lubricated disks, and established what became the dominant HDD technology. Additional uses for the floppy were later discovered, making it the hot new program and file storage medium.

The IBM3340 hard disk drive (HDD) that began shipping in November 1973 pioneered new low-cost, low-load, landing read/write heads with lubricated disks, and established what became the dominant HDD technology. Although modern disk drives are faster and hold more data, the basic technology is the same, so Winchester has become synonymous with hard. The underlying system software, which we wrote from scratch, was interrupt driven, so we could support simultaneous I/O operations, such as keying in commands while the printer was running or typing ahead of the 10 character per second teletype. Spurred on by the RAMAC series' success at high profile venues, like the 1960 Olympic Winter Games, IBM made more headway.
