Applications

The Quantum 20.5AT was a mainstream desktop hard drive of the late 1990s and early 2000s, widely used as the primary storage drive in Gateway, Dell, HP, and other OEM desktop PCs of that generation. IDE/EIDE (ATA) was the dominant desktop storage interface of the era before SATA displaced it in the mid-2000s. These drives are still sought after for restoring or maintaining period-correct legacy desktop computers, vintage gaming PCs, and older workstations that require an IDE drive. They also see use in retro computing builds and as replacements for original drives in systems running Windows 98, Windows 2000, or Windows XP on legacy hardware.
