Hi, I need to replace the HD in my Mid 2010 27" iMac. The drive that it came with is a 1TB Western Digital, and I've read somewhere that the replacement needs to be the same brand due to variations in the connectors. Is that the case? I would have thought it'd be a standard SATA connection no matter which drive I use. Also I understand there is an issue with monitoring temperature and the resulting fan speeds if I don't use the same drive as the one it came with. Is that also true? I was hoping I could replace it with a Seagate 2TB Desktop 3.5inch 8GB SSD SSHD, a hybrid drive, but not sure if that is possible. Thanks in advance for your help. iMac, Mid 2010 27"
