Upgraded to 512GB SSD, now SSD link width down to x2 from x4?
I replaced the stock 256 GB SSD with 512 GB from same generation MacBook (2015 retina) and now my SSD controller link speed and width have decreased, disk benchmark has slowed.
Is there some configuration change I need to make in order to get x4 link width and back to better speeds?
256 GB/stock SSD:
512 GB/replacement SSD:
Is this a good question?
