Know what this is?


5MB memory storage in 1956


Its one of the first magnetic hard disks made, this IBM 350 disk storage unit was able to store 5 megabytes of data and was a major part of the IBM 305 RAMAC, an electronic general purpose data processing machine system that was launched in 1956.

The 305 RAMAC was one of the last vacuum tube systems designed by IBM.
More than 1,000 of them were built before production ended in 1961 [more]


What a contrast to nowadays where we carry gigabytes of data in our USB flash drives while still complaining that they are either too large or don’t store enough data!
