I just came across a washing machine that advertises its 1200RPM spin cycle, for superior water extraction. Hey, I thought, that's approximately the speed of a slow hard drive.
Why not combine the two? Just magnetize the outside of that gigantic spinning drum, add read/write heads, and you've got
a gigantic secondary storage device.
As washing technology improves, no doubt we'll soon see 5600RPM spin cycles, and performance will approach the traditional drive.
Data loss may occur if washer is not loaded evenly.
