Checksum Errors with certain SSD

I agree this is a subject that should not be ignored as a WD Green just came up as the third search result for economic SSD's. I also see SM2262 used in kingston's KC2500 SSD's released last year which will have to be tested to see if they are also affected by this issue.

Actually the issue is still current. I just got an Intenso High performance SSD and use it with a SATA to USB adapter and have the same issue. I'll try disabling trim and see what happens.

It seems the affected SSDs left the wide market before I got to this,

I think I have the same problem, please have a look here:

I replaced a brand new SanDisk SSD  boot drive. Now I am running a brandnew WD Green SSD and it is reported as DEGRADED too.

 I can provide further information, if required.

Scratch that, my WD unit with older firmware suffers from this as well, despite the older firmware:
