I can usually get one done in about 10 minutes.

this is the one i got for my macbook pro 13" mid 2012 (non retina): double check your model number to be sure.

I actually replaced the SATA cable a few months back so it's relatively new. With this one to be exact: https://www.amazon.com/gp/product/B00GJQCJWG/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

It should be capable with SATA III, no?

Edit: according to another buyer it does apparently

Amazon Macbook Cable

This is the cable I bought from Amazon with pretty decent reviews...I do not believe it was made from China. I've also ran tests to check on the HDD and so far it's seems to be good.

When I run the AHT, it always gets stuck while testing the logicboard though.

Thanks I'll refer to that when I change it.

Do these ones look compatible?

Sorry for all the questions just want to make sure I get the right thing

As you can see from the link below and to the posters above point that model number runs about 4 years.

This appears to be the correct Hdd cable for your system

Try reinstalling mac os. If that doesn't resolve the issue try replacing the Flex Cable. They often break on these models.
