I recently got an SSD, first couple of months it worked fine as hell, but recently the performance had severely weakened. It's plugged into an m.2 port. I'm using the MSI Z270 Tomahawk motherboard. Any suggestion, fixes or reasons why this is happening?
Free up some space, SSDs require around 10-25% extra space on them for data "Swaps" (When you delete and add files the SSD moves items around in blocks, You need free space for this to happen.)
