Quantum Bigfoot (original series)
Retail 1.2/2.5 GB drive
The first generation Quantum Bigfoot drives were introduced around May 1996[7] and offered in capacities of 1.2 GB (1 platter, 2 heads) and 2.5 GB (2 platters, 4 heads),[8] 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.[9]
