That is, you definitely want to use Opal 2.0 for some drives. Opal 2.0 is not backward compatible for a good reason.It is hard to find out if Opal drives support both versions before actually getting one and spending ( wasting) time testing it.Not all Opal drives take this dual support approach.However, I really don’t think that this is a good idea because: That means, at least in theory, one could use old Opal management software that was written before Opal 2.0 to manage these new drives. I am not sure why it took so long but as a member of the Storage Work Group I can attest to the fact that that a certain amount of debate and intellectual rigor goes into the review and editing of all documents including the FAQs.įrom the TCG FAQs you can read that the Opal 2.0 specification is not backward compatible with the Opal 1.0 specification but that the drive manufacturers may choose to support both standards in the same drive. However, now that most of the drive manufacturers that supported Opal 1.0 now have, or will soon have, Opal 2.0 drives I have been getting more inquiries about the differences between them.įortunately, 1 year and 4 days after the specification was published the TCG Storage Work Group published a FAQ for Opal 2.0. The Trusted Computing Group (TCG) published the Opal 2.0 specification for SEDs in Feb 2012 so this isn’t a new topic.
