Slow & errors with Samsung 860 EVO

I recently had a new PC for myself:
intel i7-10710u (32GB memory)
SSD drives
Samsung 870 EVO Plus  1TB (M2)
Samsung 860 EVO 1TB  (SATA-3)

I have a issue with the Samsung 860evo ssd.
During coping of many (small and big files) long operations it gives i/o error's.
Writing data over network to my synology if faster then writing data to this 860Evo
Which surprise me a bit, is this normal?

I run Crystal disk mark on the disk but i do not know if this is normal:

Yea, something definitely seems wrong. Your sequential R/W performance should be 550/520. It's definitely struggling on write. Have you checked to see if there is updated firmware for this drive? If not or updating firmware doesn't help, I would be returning this drive for replacement.

Hope this helps,

Thanks,
yes I already checked and seems to use the latest Samsung driver & Intel drivers.
I will i give it a spin with an external usb3-to-sata adapter . if that works better then it's the internal SATA flatcable and not the drive.

@Hugo_W   You can update your drive's firmware from here, as well as finding the proper driver:

Thanks,

but : intel webpage with 3rd party products suggest this samsung drive as OK.

The samsung ssd is working fine attached externally using usb to sata adapter!

So this conclude the intel nuc sata cable might bad.
So how can I be sure the intel nuc SATA cable is working fine?

Any hint/tips are welcome?

The fact that a drive is listed as compatible does not mean that a particular drive will work properly. Similarly, because it is new doesn't mean that it is going to work properly; there are lots of duds right out of the shrink wrap.

I also believe that the fact that it seems to work better in the USB assembly does not necessarily mean that there is something wrong with the cable. That's a leap of logic that doesn't fly. There are lots of other reasons why it might be acting strange. I still believe that this drive is bad and should be replaced.

It really surprise me ...  feels like there is a issue with the intel nuc.
What can i tweak in intel nuc bios for this ? (it has latest firmware / bios updates)
What can i tweak in Windows 
What can i tweak in Samsung ? (they all have latest firmware)

I replace the disk with a samsung 860 QVO 1TB and run CrystalDiskMark  on it.

I can see that your NVMe is running well, close to spec. speeds. It is your SATA drive that has the issue. Have you tried using a different SATA port? different SATA cable?

Thanks for the quick reply.

1 - I don't know, but the intel NUC intel NUC i7 -10th generation does not come with any spare SATA ports in the box
2 - I don't know, but the intel NUC does not come with spare SATA cables in the box

Looks like intel has some (out-of-the-box) issue with the onboard SATA port and/or flat cable.

I have to hunt the WWW for spare parts of the intel nuc i7 10th gen. to get me some flatcable.

This intel nuc was a ready a replacement for the previous NUC because it was dead on arrival.
So far this intel nuc did not bring me any luck or pleasure.
