I tried looking into what savikalpa samadhi is (and nirvikalpa samadhi too), but I can't see where is the correspondence between the hindu names for the different levels of samadhi and the buddhist ones. We are all humans so we all experience the same states of samadhi. We just interpret them in a different way. Since you know the hindu perspective better, listen to this teaching about the 8 levels of concentration, as understood by Theravada. Then you can form your opinion.
If you have doubts about terminology, or any other thing, drop by.
He turns his mind away from those phenomena, and having done so, inclines his mind to the property of deathlessness: 'This is peace, this is exquisite — the resolution of all fabrications; the relinquishment of all acquisitions; the ending of craving; dispassion; cessation; Unbinding.'
