Hmm, that's an odd noise! Or atleast it sounds odd on the vid. Have you tried taking the aux belt off to check its not a tensioner/pulley causing the noise?
Tbh it sounds kinda like the turbine scraping the inside of the turbo though, but you'd know if it was that....
Edit - Just listened to it again, definitely a bearing of some sort!
