What you'll need: T6 screwdriver PH000 philips screwdriver SATA to USB connector ( or SATA to Thunderbolt if you feel like spending the cash) Apples DiskUtility Application 2.5 inch SATA SSD (e.g. Samsung 850 EVO), size is up to you Before we swap the drives out we want to test our speeds so that we can compare with what we get afterwards. You can run the below commands a few times, then take an average if you want a better representation. Write Speed (16GB file, lower the values of the bs and count params for a smaller file) 52.872 MB/sec write speed Read Speed 50.6726 MB/sec read speed Also, in the Disk tab of the ActivityMonitor you can see a real-time measurement of reads/writes per second, which where an approximate match to the values I got above. Hook up the new drive The next thing to do is clone the current disk over to the SDD. I used a SATA to USB connector I found online to connect it to the Mac and I used the DiskUtility app to clone the disk. Onc
