E errolng Reputable Oct 10, 2014 14 0 4,510 Aug 11, 2018 #1 Just got a Samsung 860 EVO and its read/write is only at 340+/360+ MB/s. My old 850 PRO which is about full currently runs at around 440/470 MB/s. Any ideas as to why this is so? Using a 4790k with a Asus Maximus Hero VII. Thanks in advance!
