Corsair Force NVMe PCIe M.2 240GB - slow?

father-ted · 17 May 2020 at 10:24

Hi,

Corsair m.2 drive 240gb has my OS.
Latest firmware.

Just done a quick online test at userbenchmark.com and it states that the drive is 'slower than expected':

Corsair Force NVMe PCIe M.2 240GB-£50
8,513 User benchmarks, average bench 162%
160GB free (System drive)
Firmware: ECFM12.3 Max speed: PCIe 5,000 MB/s
SusWrite @10s intervals: 306 282 291 291 287 288 MB/s
Performing below expectations (36th percentile)

Sequential:
Read 805
Write 617
Mixed 603
SusWrite 291
129% 579 MB/s

Random:
4K Read 46.6
4K Write 143
4K Mixed 64.9
229% 84.7 MB/s

Deep queue 4k:
DQ Read 715
DQ Write 559
DQ Mixed 279
306% 518 MB/s

W10 64bit
What could be the reason for this / how do I fix?

I have a Corsair m.2 1tb drive for games, which is performing to its full speed.

Thanks

What motherboard you useing also check again useing a different test in case it's a glitch in the test software

Another queston for "What motherboard?" I expect (like mine) it will be operating at PCIe 2x instead because of your motherboard, thus limiting it to ~800Mb/s

That's what I'm thinking aswell

Mobo in my sig - Gigabyte Aorus Master x570

Using the exact same online test, the 1tb m.2 drive scores as follows:

Corsair Force NVMe PCIe M.2 960GB-£170
10,115 User benchmarks, average bench 233%
562GB free
Firmware: ECFM22.5 Max speed: PCIe 5,000 MB/s
SusWrite @10s intervals: 1625 942 949 958 952 947 MB/s
Performing above expectations (82nd percentile)

Sequential:
Read 1,486
Write 2,496
Mixed 1,672
SusWrite 1,062
380% 1,679 MB/s

Random 4k:
4K Read 57.2
4K Write 193
4K Mixed 84.7
297% 112 MB/s

Deep queue 4k:
DQ Read 1,156
DQ Write 1,027
DQ Mixed 1,134
839% 1,106 MB/s

I cannot understand why they are so different, cant be the mobo as the 1tb is much faster.
Could it be a setting in W10?

Thanks for your help.

Try uninstalling and reinstall then check just in case it's a mount issue

Just tried AS SSD Benchmark - and getting 2586.48mb/s read / 656mb write
So could just be a glitch with the online test maybe?

Could well be mate which was one of my origanal thoughts just keep your eye on it if your like me it will bug you for ages now

father-ted · 17 May 2020 at 15:43

Its bugging me like hell lol

pugheaven · 17 May 2020 at 16:09

yeah that's crap that is running badly there. So, that board I think is a PCIE4 so you should be gettign PCIE4 speeds I think... so you should be looking around... I'm running an NMVe through a PCIE3 sot and I'm getting so deffo soemthing up with yours.

Userbench isn't the best when doing these so use Crystal Diskmark or AS SSD Benchmark mate and post scores.

Guest2 · 17 May 2020 at 16:11

What does CrystalDisk benchmark show?
I didnt notice you were using some random online tool to check speed

Userbenchmark.exe

Downloading that would be like giving your PC HIV on purpose

Checked in the bios and was set on gen4 - changed it to gen3 and speeds have improved

hat seems still to be slow that, I'd expect 3gb read/write on the top line as you can see from mine above, that really is slow BUT saying that, I don't know wjhat spec your NMVe is actually thinking about it... is it the 600 Corsair? With it being a smaller drive it will be slower, but I'd not expect that much slower than say the 1tb etc?

father-ted · 18 May 2020 at 16:58

510 corsair - 3100 read / 1050 write
So is in line with that

On buying it for OS I didn't realise it was a lot slower 'write' than the 1tb
System is snappy though, so happy with it given the low cost

Ahhh yeah cool, then yeah that's spot on mate and working, yeah I mean slow is relative... tbh in real world use mate you wouldn't notice any difference to mine, benchmarks are meaningless really, so unless you're copying massive files day in day out then you would see any difference betqween our M2 drives. Nice to see your sperfoming to spec now!

I only use benchmarks to check that everything is working ok.
My OCD kicked in when I saw that my OS drive was not performing as it should.
Served its purpose, didn't realise it was set to gen4 in bios = changed it to gen3 and all ok again

Same here mate you want it performing top notch that's it's capable of, I'm like you if something is below what you think, can't sleep properly, glad youv'e sorted it though!

Just wanted to jump on this thread so apologies for the hijack as I have an MP510 480GB that also holds my OS and my benchmark results seem a bit strange as well, mostly the Writes though.

I have the drive installed in the top m2 slot on my motherboard (B450 Mortar Titanium) after I realised that I had orginally installed it in the bottom slot which only allows half the speed. When it was installed in that slot the Read was halved (as you'd expect) however the write stayed the same at around the 550-600MB/s.

I thought it might be a temperature issue but from the Samsung Magician software it reads the drive at around 50 degrees C so my only other theory is free space.

I have a second NVMe installed in the bottom slot, a WD 500GB Blue and that is recording the correct speeds (1600MB/s Read & 1450MB/s Write) so is there something obvious I'm missing?

Thanks
