Hello everyone. I recently bought a MacBook Pro 15" Late 2013 2GHz. I'm running the latest version of Catalina 10.15.7
I swapped the 256GB Apple OEM SSD (Samsung chip based), and replaced it with a Samsung 970 Evo NVMe 500GB along with the gum stick M.2 adapter. I'm noticing 1675 MB Read / 1523 MB Write. It's definitely an upgrade from the stock 820 R / 665 W I was getting before. But the speeds are not up to spec. Is the motherboard for late 2013 PCIE 2.0 ?
Also when running bootcamp along with Windows 10, I installed Samsung Magician, and it also gives me the same read/write speeds. Regardless if I use the Samsung NVMe Driver or not.
Either way, I'm happy with the result, just trying to get the most out of the drive, or as optimized as it can be.
That speed is about right, 2013 model only support 2x4 . Only 2015 15" model can do 3x4, so nothing wrong with your setup
