Applications

The Seagate Medalist series was Seagate's mainstream desktop hard drive line through the mid-to-late 1990s, targeting the growing consumer and business PC market during the IDE/ATA era. Drives like the ST34342A were standard equipment in desktop PCs, workstations, and entry-level servers of that period — a time when 4GB represented a substantial amount of local storage. Today, drives in this capacity range are used primarily for maintaining and restoring period-correct vintage computers, DOS/Windows 95/98-era systems, early industrial PCs, CNC controllers, and embedded systems that require a specific small-capacity IDE drive and cannot use modern SATA hardware. They are also collected by vintage computing enthusiasts. The 40-pin IDE interface was the dominant desktop storage standard from the late 1980s through the mid-2000s before SATA took over.
