Does SSD get slower when full?
The benchmarks are clear: Solid-state drives slow down as you fill them up. Fill your solid-state drive to near-capacity and its write performance will decrease dramatically. The reason why lies in the way SSDs and NAND Flash storage work.
What percentage should SSD be free?
You generally want to leave about 10% free to avoid fragmentation (Source.) If your drive is consistently more than 75 or 80 percent full, upgrading to a larger SSD is worth considering.
