I just got my new 990 Pro 2TB, did some test, and found out on Crystaldisk and Samsung Magician that my writes speed are very low. I got everything updatet and my Motherboard support Gen4
What should I do, is it a known Problem? did anyone solved that before?
Solved! Go to Solution.
I just installed a new Samsung 990 Pro yesterday. My sequential write speeds were only 350MB/s and other write speeds even slower. My read speeds were fine and my Temps were also good. I couldn't figure out the problem. I tried a free version of a program called "EaseUS Partition Master" I ran something in the software called "4K alignment" to my surprise it completely fixed the issue and only took about 30 minutes or so. My writes are now 6,700MB's+. I highly recommended giving this a try before returning or doing a RMA on your Samsung SSD.
I hope this solution helps all of you as it did for me!
