The hard drives are not special, they are like any other drive. I believe they are not the 3.5" in traditional desktops, but the 2.5" drives you find in laptops. The 2011 could have been configured with an SSD, which is important to know if you want to replace it.

My 2011 iMac is acting like the hard drive is going bad. It freezes up on me, and I have to restart it using command+r, and reinstalling the OS. Does the iMac take a special hard drive, or will any hard drive do. Thank you so much!
For the "Mid-2011" models, OWC once more touched off a firestorm across the blogosphere by reporting that Apple had gone even further in the company's effort to restrict hard drive upgrade options:
For the main 3.5" SATA hard drive bay in the new 2011 machines, Apple has altered the SATA power connector itself from a standard 4-wire power configuration to a 7-wire configuration. Hard drive temperature control is regulated by a combination of this cable and Apple proprietary firmware on the hard drive itself. From our testing, we've found that removing this drive from the system, or even from that bay itself, causes the machines hard drive fans to spin at maximum speed and replacing the drive with any non-Apple original drive will result in the iMac failing the Apple Hardware Test (AHT). . .
We've installed our Mercury Pro 6G SSD in that bay, it too results in ludicrous speed engaged fans and an AHT failure. In short, the Apple-branded main hard drive cannot be moved, removed or replaced.
Needless to say, the obstacles to upgrade the hard drive in these models was quite disappointing. Thankfully, OWC's SSD Upgrade DIY Kits now overcome all of these obstacles for each line and taking the computer apart and putting it back together again is the remaining challenge.
