The 2TB hard drives offered as build-to-order options for the iMac are in short supply due to flooding in Thailand, reports “Neowin” (http://macte.ch/Gph7p). Over 50% of global hard drives are made in the country, the article adds.
According to the Apple website it could add anywhere from five to seven weeks to the delivery time due to the sheer difficulty of sourcing 2TB hard drives for the machines. The Mac Pro line can be outfitted with as many as four 2TB hard drives, though when doing this, the delivery time for the machine doesn’t increase.
This may suggest that Apple are holding any 2TB hard drives they have available for usage in the Mac Pro line over the iMacs at present, notes “Neowin.” iMac with 1TB hard drives face no delays in shipping.
