Up until now, if you wanted a new 21.5-inch 2012 iMac from Apple, you had pretty dim prospects when it came to storage: your only options were a a stinky 1TB 5400RPM hard drive, or spending an additional $250 on a 1TB Fusion Drive. There were no options for a pure flash storage iMac, and on the 27-inch iMac side, things weren’t much better: the only thing you could opt for in a build-to-order iMac was a $900 768GB SSD.
That’s all changed for the better now, though. Apple has quietly updated build-to-order options across its iMac line to allow you to replace your new iMac’s 1TB hard drive with a 256GB or 512GB SSD for $300 and $600, accordingly. That’s actually pretty expensive for an SSD — which cost about $0.66 per GB on Amazon right now — but given what a royal pain-in-the-neck performing any surgery on Apple’s glued shut new iMacs is, it’s your only real option if you want a flash drive in your iMac.
