Applications
The Quantum Plus Impulse series was a widely used line of 3.5-inch SCSI hard drives from the early-to-mid 1990s, a period when narrow SCSI was the dominant storage interface in workstations, servers, and high-end desktop systems. Drives like the 105S/C were commonly installed in UNIX workstations (Sun, SGI, HP, DEC), early Apple Macintosh systems with SCSI controllers, PC-compatible servers running NetWare or early Windows NT, and embedded industrial systems requiring reliable fixed-media storage. Procom Technology was a major OEM reseller and systems integrator of that era that sourced Quantum drives and rebranded them for direct retail and system integration — the Si100 designation reflects that distribution channel. Today these drives are sought after for restoring vintage workstations, SCSI-based legacy systems, and period-correct retro computing builds.
This Quantum Plus Impulse 105S/C 105MB 3.5-inch 50-pin SCSI hard drive has been tested, formatted, and wiped, and is in good working condition. All previous data has been securely erased. The drive shows normal cosmetic wear consistent with prior use — the top label is intact and legible, and the 50-pin SCSI connector appears clean.
