When Seagate originally developed the ST1 hard drive family of devices in 2004, they were remarkable little critters. Measuring just a bit larger than a conventional Compact Flash media card, the ST1 was a full-fledged 3600 rpm platter spinnin’ hard drive. Armed with a large 2MB cache buffer and an average seek time of 16 ms, the ST1 was stoked with Seagate’s RunOn (the heads are forced to stay on track) and G-Force Protection (the heads are removed from the platter during power down) technologies. Yet, the ST1 sported a Type II Compact Flash interface.
