Opal, Opalite & Pyrite Self-Encrypting Drives (SED) Simplified

This year (2015) the Trusted Computing Group (TCG) Storage Work Group (SWG) published two new specifications derived from the Opal SED specification called Opalite and Pyrite. You may already be familiar with the benefits of using an Opal SED vs software encryption in your laptops and desktops, but are puzzled as to why there are 2 new standards. Perhaps you even wonder if they would be a better fit for your needs than Opal.

Encryption Alphabet Soup

Learning a multiplicity of acronyms is pretty much a requirement for navigating any discipline. Every field has its own set of acronyms and the sequence of 3 or 4 letters that usually make up the acronym most likely has a completely different meaning from discipline to discipline. Even within a discipline it is common to see the acronyms muddled together.

How SEDs Really Work

I have been working with hardware and software encryption for well over a decade now and I have seen countless power point presentations on the advantages of hardware encryption over software encryption.  Transparency, performance and security are the big three.
