Two-to-four 3340 drives could be attached to the IBM System/370 Model 115 processor -- which had been announced concurrently with the 3340 -- providing a storage capacity of up to 280 million bytes. The very first small winchester disk drive was the ST-506 which boasted a generous 5 MB (five megabytes) of storage. It had a 20MB capacity on two disk platters. 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. Project head Kenneth Haughton named it after the Winchester 30-30 rifle because it was planned to have two 30MB spindles; however, the actual product shipped with two spindles for data modules of either 35MB or 70MB. There were some conditional commands (like IF DISK) for use in batch files. Although modern disk drives are faster and hold more data, the basic technology is the same, so Winchester has become synonymous with hard. What made this drive significant is the technique where the read/write heads would rise or lift off from the disk while the disk increased and lowered when the disk decelerated. The term for hard disk drive. The Winchester technology allowed the head to land and take off from the disk media as the disk spun up and down. As of 2020 SSDs started to compete with HDDs.
