Why is my Micron_3400 NVMe sdd's write and read speeds are too low PHN16-71

hamurci · May 20

Today I've bought a new 4tb ssd which has lower write and speed values.I've installed it to my Acer Predator Helios Neo 16 (PHN16-71). I did a speed test on my new ssd and saw 3500mb/s value.Than I tried that test on my pre-installed Micron_3400 1tb ssd and it resulted 885mb/s. I did some google'ing and Micron ssd has too much higher write and read speeds by default(almost 6000mb/s). Why could that values be that low on my pc? Welp!

The Predator PHN16-71 laptop has 2x M.2 slots that are of the Gen 4 x4 lane type, the 4TB M.2 Micron 3400 SSD is a Gen 4 x4 lane drive and is quoted by Micron to operating at speeds of sequential Read: 6600MB/s and sequential Write: 5000MB/s. Try to test the drive with a different M.2 SSD benchmarking software than the CrystalDiskMark as this software sometimes does not install properly and is faulty and gives faulty results, try the ATTO Disk Benchmark, or AS SSD Benchmark as they are more reliable and see if the 4TB Micron 3400 drive gives its oem read/write speed results. Good luck as I'm sure that the testing is wrong as the PHN16-71 M.2 slots is quicker than your tests above. For a better guide but this does not have the 4TB Micron 3400 M.2 SSD there, have a look at the SSD Benchmarks Hierarchy 2024 for 1TB, 2TB and 4TB M.2 SSD drives done by Toms Hardware, as its a very useful guide.
