2012 MBP 13inch hard drive cable replacement

My Problem

Erratic and slow performance with a 1 TB SSD after replacing the original HD which was also slow. When running the mid 2012 MBP 13 inch from the SSD via USB the computer ran fine.

My Fix

So ordered hard drive cable from ifixit and replaced the old one. Worked great. with the SSD it is about as fast as my work MBPro 2015 or my late 2014 macmini with 16 GB of ram and hybrid drive.

Ifixit instructions from the web site were great and clear.

My Advice

Figure out an easy way to replace the hard drive in a 2009 imac please!!!
