Whenever I am downloading games the ssd reaches 90% usage
How much free space do you have on the SSD? If less than 30% is free (which might not be the case on a brand new laptop) the disk controller might spend more time looking for free blocks.
To check the SSD, download a trial copy of Hard Disk Sentinel and run a Surface Read-only (non destructive) scan, which might take several hours.
A more thorough (non-destructive) test would be a Write/Read Surface scan. This moves small blocks of data to one side, writes to each block, checks integrity and restores data to the block just tested. This test takes twice as long.
