both ssd's low IOPS

[NatteDraak]

Hi,

Both my Samsung EVO 840 120GB and 500GB suddenly report very low IOPs, causing a big performance hit of my laptop (works very laggy).

Any idea of what happens here? This is the third time in 4 months. . .


A recurring EVENT 225 seems to happen everytime this problem arises, for example:

The application \Device\HarddiskVolume4\Program Files (x86)\Google\Drive\googledrivesync.exe with process id 6908 stopped the removal or ejection for the device PCI\VEN_8086&DEV_8C03&SUBSYS_06551558&REV_05\3&11583659&0&FA.


Thanks for reading, greets


EDITED: new question because of new info

Do you have the Samsung magician tool installed? It will tell you the health of your solid state drive.

 

[NatteDraak]

Thanks for answering. Samsung Magician reports Good Health. I installed the latest AHCI drivers, Intel RST.

Btw, after restarting, my event viewer is filled with 225 events, regarding processes stopping the removal or ejection for my harddisks . . .?

I would suggest trying different sata port on the same controller. Then if that doesn't produce different results try a different sata controller port if at all possible. Does this change results any?

 

[NatteDraak]

I have only one mSata port for the 120GB EVO, but since the second EVO (500GB) also produces the error, I don't think that helps?

Thanks.

Can you list your full specs please?

It sounds like throttling. Is there a way you can monitor the temps of the ssds?

 

[NatteDraak]

I check it's temperature with Speedfan, it reports 63 degrees celcius. Seems pretty hot.

Do you think it went over 70 and throttled itself?

It is possible and would explain why all of a sudden your iops drop. M.2 drives and their placement on system boards have been notorious for overheating. This is why on the new 270 chipset boards, you see manufacturers starting to put thermal pad cases on them.

 

[NatteDraak]

Seems very probable then. I'm ordering a SATA adapter so I can put the drive in the DVD bay in the laptop. Hopefully with better temp results.

Thanks a lot!

Did you recently purchase this? If so contact technical support and open a support case.

Thing is though, why would my other 840 EVO 500GB ssd ALSO report low IOPs. . .? Its temps are fine.

Could my motherboard be the culprit?

I did a quick search on the support website and didn't find a bios or driver update for your particular issue. Id suggest opening a support case with Sager:

I have removed the official Intel RST 14.8.0.1042 driver, afterwhich SSD speeds were restored to normal.
I then installed the latest modded Fernando RST drivers for Intel 8/C220 chipset (13.6.3.1001) and speeds have never been better.

I have no idea why the problem occured in the first place (I did not have RST installed when the problem first occured), and why installing Fernando's RST drivers give even better speeds than without RST (for now).


Thanks for the help so far!

I also disabled Link Power Management and activated the High Performance power plan (through gpedit.msc because after every restart in changed back to the balanced power plan). So far so good. . .
