Prices for the HDDs themselves? Doubtful, but maybe. The nice thing about consumer-grade HDDs is that consumers are not very price elastic, meaning if consumer HDD prices go up too much, consumers will just stop buying them (we saw this happen after the Thailand Drive Crisis). Hopefully what it'll mean is that drive manufacturers will instead start making lower-cost "professional" drives for this exact purpose. Cheaper than "Enterprise Drives" but slightly "better" to justify a slightly higher price than their consumer counter-parts. Hopefully...
I still haven't been able to work out if prices ever went back to pre-Thailand prices. It pretty much coincided with the beginning of the Aussie dollar becoming worthless so that's skewed things a bit.
Well, at least in the States it's gotten pretty close to those levels if not gone down to slightly below them. Not sure where that relates to the Aussie dollar though :-(
