Samsung 970 EVO 500GB - Slow Read Speed?

dark051128

From what I have seen from others and the specs, I should be getting around 3.5k in read but I am only getting around 2.5k. 

Here's what AS SSD Benchmark and CrystalDiskInfo show: https://imgur.com/a/dcVFigt

What's wrong with it? I have the latest driver installed.

Does the Samsung Magician show it running PCIE 3.0 x4?

What motherboard do you have and what slot do you have it connected to? Some NVME slots are wired into the chipset instead of direct to the CPU so this could affect your speeds as well

I have a Asus z390 prime-p, the slot is M2_1 (Socket3)

from what I can tell, that socket is wired direct to the CPU, so shouldnt be using the chipset lanes. Go download Crystaldiskmark and run that. I have a 970 Evo 1tb as well so the speed should be close. Right now from what you have linked, you're about 1200 behind mine, but I used Crystaldiskmark to run mine. So need an apples to apples comparison.

how much did you fill it up? The more the files it's holding the slower it gets, that's just how SSDs work.

So that's correct speed?

Yep. They are inline with benchmark data out there for Crystaldiskmark for the 970 evo. Also one word of caution, I found the 970 to be EXTREMELY HOT.. like the memory controller reaching 105c while I was transferring files onto it.. I would get yourself a heatsink on that things ASAP. With my heatsink my temps dropped from 105c to 74c max while performing the same actions. Here is the heatsink im using personally: https://www.amazon.com/gp/product/B073RHHYCM/ref=oh_aui_search_asin_title?ie=UTF8&psc=1

Update, why is my 970 evo dropping to 1/4 of its speed?? https://imgur.com/a/zBOVR5D
