Default When will HD and flash drive prices converge?

I'm attempting to figure out approximately when hard drive and flash drive prices will converge. I'm putting this in the Hardware section because I'm convinced that people will be interested in the answer, even if they're not interested in the mathematics.

Here are the facts we're dealing with:

flash drive space costs approximately 5 times as much as hard drive space.
hard drive space costs approximately half as much every 12 months.
flash drive space costs approximately half as much every 9 months.

So, assuming these are absolutes, even though we know they're just heuristics, when do they converge?

Solve

5 * 2-M/9 = 2-M/12

where M = number of months from now

I ran it on my calculator, and, assuming the numbers jasong provided are perfect and constant, it will be ~83.59 months from now. That's ~12 days under 7 years, which means it will be on April 15th, 2014 that their prices converge.

wouldn't you need to factor in the fact that new mfg methods and different technologies that would reduce the cost of production of flash drives and replacement of hard drives with something else causing there prices to go up.

Sure -- just give us the appropriate numbers! :-)

With what jasong gave (which may already include the factors you mention), it's ~7 years. Besides, it's only an estimate either way.
