Just installed a new 850 evo and ran crystal disk mark.
I've noticed i have lower read/write speeds at 4k tests than online reviews. I asked a friend who has same SSD to run same test and his results are +- like in review.
Numbers :
ME FRIEND
4kQ32t1 r/w 273.2/89.59 383.1/339.0
4k r/w 35.27/68.34 37.21/117.5

I even installed Samsung magician and set the ssd to maximum performance....but didn't made any difference.
We both use the ssd as boot device.
I didn't made a clean install, i used samsung migration software to clone the old ssds (2xkingstone v300 120 gb raid 0)

i discovered that after cloning the clusters weren't properly aligned. i realigned them and now the 4kq32t1 write speeds went from 89 to 250. The rest of the readings didnt changed. still lover than others but better than befofe
