What we have is a plethora of opinions about what's wrong with IDE. Why don't you solve your problems.
1) It's unreliable over the long run. - Have multiple disks that will be unlikely to fail at exactly the same time.
2) Remote storage - Get a friend that has some space and get him to store a disk for you.
3) Jostling hard drives might reduce life expectancy. - Perhaps try remote incremental backups over the net. Do one large copy locally then locate the disk at a remote connection and backup incrementally. ( remember the local part for the first copy - I got a note from my ISP when I did it over the net.)
4) Lubricant failing in disk. - Two things, you can either replace the disks on a cycle, perhaps every two or three years. ( prices keep going down) or keep the disks spinning on a remote computer that is UPS protected.
There are many other ways to do this. What we need here is people with solutions. Not more problems. Think outside the box.
Haven taken a Microeconomic course, I find your example incorrect. The law of supply and demand shows an inverse ratio, as supply goes up, price goes down as the glut on the market increases. As demand increases, price goes up on the rarer item.

I would respond further but lack the time.
