This hard drive, shipped with the RAMAC 305 system, was the size of two refrigerators and weighed about a ton. Future hard drives after the 3340 began to use this as a standard for hard drive development. In 1973, IBM introduced a new type of hard drive codenamed "Winchester."

The term Winchester comes from an early type of disk drive developed by IBM that had 30MB of fixed storage and 30MB of removable storage; so its inventors called it a Winchester in honor of its 30/30 rifle. HDDs continued to get smaller with the introduction of the 3.5-inch form factor by Rodime in 1983 and the 2.5-inch form factor by PrairieTek in 1988. The first disk drive to use removable media was the IBM 1311 drive. 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. Unit shipment has been in a slow decline since then, shipping about 276 million units in 2018 with a somewhat slower decline projected thereafter.[25].
