Seeing hard drives sold for only about four cents per gigabyte isn't all that uncommon right now, but things may change over the next few months. DigiTimes reports that a shortage of mechanical hard drives could hit us in the second half of the year.
Somewhat surprisingly, DigiTimes blames the March 11 Japanese earthquake for the expected shortage. (At least, it quotes Taiwan-based manufacturers of drives and components who do.) Word is that Texas Instruments and Renesas, the "global suppliers [of] HDD chips," have finally been able to resume operations following the quake. However, those companies need to get their products certified again, which will reportedly leave them "unable to restore original output quickly" right as demand peaks next quarter.
I suppose now may be as good a time as any to stock up on mechanical storage, then. Of course, modest price hikes and a few out-of-stock products here and there wouldn't exactly be the end of the world—not when 2TB Caviar Green drives are selling for $79.99 right now.
