Yes, i used to be one among the scholars who continuously rummage around for a decent factor on the web and ne'er do a favor for one more students however I got an incredible web site that's known as https://www.college-paper.org/write-my-college-essay/ essay geeks which will facilitate anyone through internet to form your assignment look more real and freaking good although additionally you wish to prepared few more things.]]> Fri, 15 Apr 2022 01:02:13 +0000 https://forum.asrock.com/forum_posts.asp?TID=21245&PID=97845&title=x570creator-transfers-between-nvme-maxes-at-2gb-s#97845 https://forum.asrock.com/forum_posts.asp?TID=21245&PID=93112&title=x570creator-transfers-between-nvme-maxes-at-2gb-s#93112 Author: kerberos_20

nvme drives doesnt have all that speed available, there are some limits

first, drives have ram cache, which would max out bandwith limits.. its what you also see in some drive speed benchmarks...ram cache is relatively small, once its filled up, drive will switch to a lower tier caching, which is SLC cache, drive itself works as mlc (2+bits) which is slow, but if it uses only 1 bit per cell (slc) then speed gets boosted up, slc cache has also limits, but its much bigger than ram and provides like 2x faster speed than mlc, once that fills up (lets say 30GB), drive will slowdown to its native mlc speeds. Once finished working with drive, ram/slc cache will empty itself overtime (moved to mlc area)]]> Sat, 19 Feb 2022 05:20:17 +0000 https://forum.asrock.com/forum_posts.asp?TID=21245&PID=93111&title=x570creator-transfers-between-nvme-maxes-at-2gb-s#93111 https://forum.asrock.com/forum_posts.asp?TID=21245&PID=93109&title=x570creator-transfers-between-nvme-maxes-at-2gb-s#93109 Author: CBMe

Issue:
My individual NVME drives will test around the rated speeds for sequential Read & write.   However when transferring a large file between them, in either direction, the transfer will quickly level of at 1.9 to 2 GB/S.   

I do not understand why I could use them individually at full speeds but they are being throttled when writing between them. This would seem to indicate that it is being limited to PCIE 4.0 x1 speeds to NVME 1 but I do not understand why that would be or how to fix it.

Thoughts on how to get this system working at full speed?


Environment:
Primary NVME - Samsung 980pro 4.0 1TB 7000 read / 5200 write
Secondary NVME - HP EX950 3.0 2TB 3000+ read / 2500+ write

Windows 11. Fully updated. Latest drivers. NVME controllers using Windows driver. Latest firmware for SSDs.
