Compact flash card hard drive. This is just crazy. When I first heard about these things my jaw literally dropped (not literally). They are obsolete now, having been hopelessly beaten by solid state flash memory, but in their day they were the highest capacity compact memory cards available, up to 8GB by 2008 (by which time 64GB flash memory cards were available). And they are mechanical hard disk drives. Let me remind you of the dimensions of a compact flash card (type II): 1.4" x 1.7" x 0.2" (36.4mm x 42.8mm x 5mm). The platter in this drive is about 1" (2.5cm) in diameter. It's just crazy small. There's an electric motor spinning the platter, an electro-magnet that moves the read-write heads back and forth, the whole works, plus of course all the control and interface electronics, packing into no space. I stand in awe of this device. The platters are aluminum, the electronics are silicon, the wiring is copper, the magnets are neodymium iron boron, and the magnetic coating is iron and cobalt based.
