I've always been curious why drive manufacturers have not produced a hard drive that is super slow and with a massive capacity.
I may be mistaken, but it is my understanding that a low revolutions per minute would extend the life of a drive, even enabling its platter size to increase in diameter, and possibly lowering power usage.
I imagine a 5.25 inch drive with a massive capacity that could be used as a backup drive, that would be powered down most of the time by the computer.
I could understand that a drive like this would not be in WDC business strategy.
However, I would think a very slow drive would not compete with their other product offerings, but would be a great product for online archiving.
