Worked well overall; docs missing a few details
1 - 2 uren
I wanted to use an SSD as the primary drive and maintain the original 1TB drive as a secondary.
It went okay for the most part. I noticed all the tear-down docs (among models) were the same with the same images. Mine looked slightly different like my original was bolted in (docs suggest it rests and should be pulled out). Also, the cable for the secondary was the exact same size as the original; so I had to fold it in a way to make it "reach" the secondary port, which was the most difficult part. I was concerned I would stress the cable too much. But it worked in the end. The top drive also just rests on top of the original. The docs didn't explain that well with imagery.
Otherwise; once the hardware was re-assembled, I was able to boot up and use a cloning tool and rsync to move files around. I used the Mac Startup Disk tool to switch default boot up, then I erased my original 1TB drive and moved big stuff back over to it. I used symbolic links for things like Movies, Downloads, Pictures, Music etc in my home directory to push them off the SSD and onto the HD.
Just that those cables are the same length. I mounted the original disk drive (HDD) in its original location and plugged its cable into its original spot. Then maneuvered the second hard drive cable (SSD; my new boot drive) to work with the secondary port.
