hard drive upgrade

Hi,

Yes. That's exactly what I have in myMacBook Pro 13-inch mid 2012 (non-Retina). It has been running without any trouble for more than 2 years. Before that I had a Samsung 840 EVO.

Best to put it in the hard drive bay. You could also replace the SATA cable that connects the drive to the logic board as the MacBook Pro unibody is know to develop problems through wear and tear on this cable.

You're welcome!

If you are going to do it yourself, you need a replacement cable. The best place to buy is probably OWC. Here: https://eshop.macsales.com/item/Apple/8211480/

There is an install video which you can also use for replacing the hard drive.

Some people replace the optical drive with the old hard drive or an SSD to increase storage space. You need an enclosure to do this. You can find guides for this at OWC and iFixit, and elsewhere. I preferred to keep the optical drive.

Regards and good luck!
