I have 2x EQ12 16G/500G bought from Amazon, both running Proxmox.

One has a 1TB Samsung 870 EVO SATA drive with no issues.
The other has a 2
TB Samsung 870 EVO SATA drive which sees many errors like this ...

It appears to be a known issue with the Bee-Link's use of unshielded SATA ribbon cables.

I am going to try a Crucial MX500 (as in my experience, they are more immune to noise).But I think the issue really is down to Bee-Link's design.

It appears to be an issue only at 6Gbps.
When I boot the kernel with 'libata.force=3.0Gbps', the problem seems to go away (but the performance is poor).

Do you have a better cable option?

I have wondered about applying some adhesive metallic tape to the cable.
Is this likely to help?

UPDATE...

The 2TB Crucial MX500 has been running fine. I have written over 600GB to it without a single CRC error.
The 2TB Samsung 807 EVO worked ok when restricted to 3Gbps, and works ok using a SATA to USB adaptor.

Two theories ...

1) the Samsung is more sensitive to noise on the SATA bus
2) the Samsung generates more noise which gets picked up by the SATA bus

Either way, I can't help thinking that the issue is with the unshielded SATA ribbon cable in the EQ12.
