I am starting this thread to collect the information about Self-Encrypting Drives (SED) which and compatible or not with TGC OPAL 2.0 standard. This information is rarely provided on manufacturer or store websites so I decided to encourage everyone to share valuable information about SED to save people nerves and time.
Linux can utilize hardware encryption on OPAL 2.0 compliant drives, so users should to know which ones really support this standard before purchase.

Recently I bought Self-Encrypting Disk (SED) with AES256 encryption from ADATA, model Legend 960 (NVMe, PCIe Gen4).
Unexpectedly
returned the information that drive does not support OPAL.
I started to look for any information if this drive support OPAL or not. No success. Then I tried to find any information if any disc of Legend family is compatible with OPAL 2.0. No results either.

Finally I wrote (at the evening) to ADATA:

Could you please let me know if AES256 encryption in SSD Legend 960 is compatible with OPAL 2.0? I can't find this information anywhere. I tried to check if few other SSD models from Legend series with AES256 support are compatible with OPAL 2.0, but cannot find this information neither. Could you please help?

They responded next day morning:

Dear customer,
We sincerely apologize for the late reply.
About your inquiry, currently our standard SSD can't support opal for AES. thank you
Best Regards,
ADATA Customer Service Center

ADATA Legend series NVMe drives (including Legend 960) are not compatible with OPAL 2.0.

Hope information gathered in this thread will help to other people.
