Hey there everyone hope you are all well and had a nice Christmas.

I got my hands on a Samsung SM961 128GB from the MM as my old SSD was on it's last legs after many good years of use.

My windows certainly feels to be faster than my old ssd after ive booted up but i think this nvme drive is not seem to be giving me everything it has ( more on that later )

here is a screenshot of a cdm benchmark

These are the speeds i was expecting

- Read Speed: 3100MB/s
- Write Speed: 700MB/s
- IOPS: 330k/170k

While the write is a little faster than expected i seem to be missing a fair old chunk off the read. This would not have bothered me so much but i am now experiencing other issues that i can't live with that might be related.

My main issue being downloading anything to the drive from steam, the steam downloads start and stop and can't reach 1mb/s on the ssd as it for some reason on task manager reads the drive as 100% Active time. (im not sure of the difference between this and usage) When it's like this steam wont continue to download until it settles down. I don't have this issue downloading to my dedicated steam hdd that has all my games on i download at around 17mb/s to that. Everything i do including booting windows is not exactly fast and upon checking the active time again during boot it's always at 100% but displays reading/writing at a max of 30MB/s

I have installed RST, I have installed the Samsung NVME driver, and i am running in AHCI.

Is there anything that ive potentially missed that needs updating?

Check that write caching is enabled https://www.tenforums.com/tutorials/21904-disk-write-caching-enable-disable-windows-10-a.html
 
Thanks for the reply HoneyBadger, Write Caching is enabled but turn off windows write-cache buffering flushing on the device is turned off, but i think this is to prevent data loss :)
 
Okay now another drive has started to do it,

My games HDD D: just sat at 100% usage with nothing occurring on it. I heard the arm moving back and fourth and thought something must be updating but i checked and it was under 0% load had 1.5mb/s read on it.

really starting to annoy me now :/

Tried with AV disabled? Also run chkdsk and sfc maybe?

Thanks for the advice,

I have no AV installed, and recently tested chkdsk and found no issues, i am not sure what SFC is an abbreviation of?

It's at it again now 100% at 45mb/s and becomes choppy.

here is a re run of chkdsk

What would SFC be and il have a see :)

Thanks again everyone for any recommendations they are all welcome and appreciated.
 
figured out what SFC is,

2016-12-29 15:32:40, Info CSI 00005501 [SR] Repairing corrupted file [l:23 ml:24]"\??\C:\Windows\SysWOW64"\[l:10]"opencl.dll" from store
Click to expand...

Ive just run chkdsk /b /f /v /scan for a reboot scan, il test performance again once that's complete.
 
Well sadly none of the above worked, im still getting problems.

Im currently downloading a new windows 10 iso from microsoft and am going to do a fresh install (again)

I stopped it from updating last time as i hate the clock being moved :( but il run it through the hoops to get everything.

(even bought a new key so id have a spare one)

Will update later once it's installed.

Well, my speed is certainly better now, i just made the silly mistake of downloading windows 10 pro N and not windows 10 pro, i now don't have a pen drive big enough to get the windows 10 pro install media onto as my new key wont licence pro N (a version of windows lacking media player and such):( What a day.
 
Glad its working a bit better. As you probably found out SFC scans the disk for broken Windows system files and repairs them from an original copy :)

Do you need Media Player? Thought most people used VLC Player now really.

I do use VLC, however the windows n pro that I downloaded without media player and such can't be activated with a normal windows pro key that I had. I've sorted it now I sourced a old clean ISO that was small enough to fit in my. Pen drive to boot just updated it all to current and then activated :)

Going to do some more testing of performance today.

Thanks again for the help.

LOL! Oh dear. Sort of "out the frying pan and into the fire". Hope it's all sorted for you now though :)

Well my speed is now as it should be, just fiddling around with windows trying to get it running how i like it :P going to do some performance tests shortly and make sure it's not gone haywire again.
