• Drive only — no cables or accessories Quantum Fireball CR series was a mainstream desktop hard drive line produced in the mid-to-late 1990s, widely used in consumer and business PCs of that generation. These drives were sold as OEM units into major PC manufacturers including Dell, where they appeared in Dimension, OptiPlex, and similar desktop lines. The 6.4 GB capacity was a common configuration for systems running Windows 95, Windows 98, and early Windows NT/2000. Today, these drives are primarily sought for restoring, repairing, or maintaining period-correct vintage computers — including original Dell desktops, custom retro builds, and legacy industrial or embedded systems that relied on IDE storage. The Fireball CR series was manufactured at Quantum's facility in Ireland and was known for its compact, reliable design typical of late-1990s desktop IDE drives. The standard IDE/PATA interface means it is compatible with any system or controller supporting the ATA standard from that era.
