Built-in technologies in this 3TB external hard drive will make transitioning easy. You don’t need any utilities or extra integration steps to install the hard drive into your system.

Can this serve as a replacement HD for a 27" imac (mid 2010)? I know about the thermal sensor issue, however I've checked various sources which say as long as you use the same brand of HD which your machine currently has (so you can use the sensor cable which your Mac already has) there should be no problem, and my iMac has a Seagate HD currently installed.

Best Answer

Technically, it will work with your iMac. You will have to be careful about warranty since end user hard drive configuration on your iMac is not covered.

Seagate 3TB Works Great

By Dommer 
Needed more space for Time Machine backups on my Mac Pro system. So I replaced a 1.5 TB Barracuda drive with this 3TB drive. Running Mountain Lion and it works perfectly.

Seagate Barracuda 3TB 7200RPM SATA-600 Internal Hard Drive

By Kazuo Ota Cottrell 
This drive was easy to install into the drive bay of my Mac Pro. It was recognized by Drive Utility, allowing it to be easily formatted. Performance was extremely quiet. It has operated reliably since installation, without any problems. I highly recommend this drive to others, especially Mac Pro owners looking for a drive to use with Time Machine.
