Applications
The Quantum Fireball EX series was a mainstream desktop IDE hard drive line produced in the late 1990s, targeting the consumer and OEM PC market during the era when parallel ATA (PATA) was the dominant desktop storage interface. This 8.4 GB unit was a common capacity point for systems built in roughly 1997–1999, fitting within the INT13 8.4 GB addressing limit that was standard for BIOS of that period. These drives were widely used in desktop PCs, entry-level workstations, and OEM systems — Dell deployed this exact variant in its consumer and business desktop lines of that generation. Today, Quantum Fireball drives are sought by vintage PC enthusiasts restoring period-correct systems, hobbyists running legacy software environments, and technicians maintaining older industrial or embedded systems that require IDE storage. The standard 3.5-inch form factor and 40-pin IDE interface make it compatible with any ATA-capable desktop motherboard or IDE controller card from that era.
This Quantum Fireball EX 8.4AT 3.5" IDE hard drive has been inspected and is in good used condition. The drive housing is intact with normal light wear consistent with prior desktop use. The PCB underside appears clean and undamaged. The IDE and power connectors are present and in good shape. Please view our photo set and contact us if you have any questions.
