Hi I've joined the forum just for this issue as I'm having the same slow write speed issue. As you have asked in your last post I've tried to test the speed with fast startup option disabled. The results are still the same. My drive is 10 months old now and it is the MP510 960GB. Write speed is always around 1000 MB/s and read speed 3400 MB/s. If you need I will post screenshots. please note this important note, I'm using CrystalDiskMark 6 to do the tests BUT the speed test is different from version to another! or from other application like (AS SSD Benchmark)!. For example, when I use the latest CrystalDiskMark 7 version the results is always around 2000MB/s Read and 1000MB/s Write which is different. and when testing using (AS SSD Benchmark) app the results is around 1800MB/s Read and 2300MB/s Write AND that is not the case when I test my other NVMe Intel drive which always give me correct speed test with all the programs and versions even though there is only 26GB empty from the drive from the total size 1TB. Next thing I will try is a clean format as the OS is installed on it and can't delete its driver.
