Yes, it's possible but........ Apple installed priority hard drives with temperature sensors in this model. To upgrade to an off-the -shelf drive you will need a In-line Digital Thermal Sensor for iMac 2009-2010 Hard Drive Upgrade. Without it the fan will run unabated.

OWC carries this to do the job.

I would recommend a hybrid drive for this model like a Seagate SSHD in a 1 to 4 TB.

Here's the 1 TB: 1 TB SSD Hybrid 3.5" Hard Drive

4 TB SSD Hybrid 3.5" Hard Drive
