IBM 350 Disk Storage Unit

The IBM 350 Disk Storage Unit, introduced in the 1950s, was one of the first computer disk storage systems. It used multiple large, rotating magnetic disks to store data electronically, enabling faster and more efficient data access compared to earlier methods like punch cards or magnetic tapes. The 350 could hold thousands of data bits on its disks and was used primarily for business and scientific data processing. Its innovative design laid the foundation for modern hard drives, marking a significant step toward the fast, reliable digital storage we use today.
