[Star Wars] Revan and Malek's names

Were Revan and Malek their real names? If so why are they the only sith to keep their real names with the Darth title?

If they weren't their real names then why did Revan keep Sith name when he returned to the Jedi?

The important thing to take away from Sith naming convention is the concept of choice. The Sith ideology is all about personal power and personal strength, so many Sith feel the need to "choose" their own name, to have power over everything; even what they are called.

Malak felt the need to do that, Revan did not. 

(Sidenote; Darth Vader is interesting because his name was chosen for him by Darth Sidious, which is interestingly reflective of their power dynamic)
