context_page_description: The Quantum Bigfoot brand was a series of hard disk drives produced by Quantum Corp. from 1996 through the late 1990s. The Bigfoot series was notable for deviating from the standard form factor for hard drives. While most desktop hard drives at that time used a 3.5-inch physical format, Quantum Bigfoot drives used a larger 5.25-inch form factor more commonly seen in older hard drives, CD-ROM and other optical disc drives. This form factor allowed Quantum to increase the capacity of their hard drives without an increase in data density, thus lowering costs compared to a 3.5-inch drive with the same capacity. It also allowed manufacturers and owners to install the hard drive above or below the optical drive in the computer, as the typical computer had multiple 5.25-inch bays.
context_section_description: The first generation Quantum Bigfoot drives were introduced around May 1996 and offered in capacities of 1.2 GB (1 platter, 2 heads) and 2.5 GB (2 platters, 4 heads), with suggested retail prices of $225 and $370 respectively. These drives offered only ATA-2 PIO Mode 4 and DMA mode 2 support (16.6 MBps) and had an average seek time of 15 ms. Actual transfer rate from the platters was much lower, measured at 813 KB/s by PC Magazine using Disk WinMark 96, slower than a same-capacity/similar-capacity Quantum Fireball (3.5") drive, which delivered 1170 KB/s.
