Hello everybody, this is my configuration Fatal1ty AB350 Gaming-ITX/ac Ryzen 1700 Corsair 16GB Ram Sapphire RX480 Today I received the new NVMe M2 Samsung 970 EVO 250GB. Connected it to the Ultra M.2 port on the bottom side of the motherboard. I updated to 4.60 BIOS and installed Samsung drivers, but I get these results:  Aren't them low compared to reference test? http://www.legitreviews.com/samsung-ssd-970-evo-nvme-1tb-ssd-review_204678/4 They're almost the half... |

" rel="nofollow - Just for comparison.. https://www.newegg.com/Product/Product.aspx?item=N82E16820147689 If you look at Read/Write performance, your speeds are right on. In fact, your read is slightly faster.

Yes, but here is a benchmark on a test of 250GB like mine Seq is the same, while 4K tests are almost the half, why?

12k iops thats normal, latency is ok, temperature a little bit higher, at 75° it will throttle max bandwith (read/write) from your first picure is also ok (pcie x4 gen3) anything in between is mostly windows related (cache/drivers) ------------- http://valid.x86.fr/diq4l4" rel="nofollow"> http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |
