I switched my drives to bigger on my R4 and now when I playback simple QT files my raid goes crazy. I get a really annoying hacking sound. This goes for playback from Resolve or Premiere as well.

I'm running High Sierra on my MacPro. The disc that I changed to is 4x Toshiba 6TB, recommended in Pegasus2 compatibility list.

Is there a way to get rid of this sound. Is there any recommendation when setting the raid up? I dont get any fault in the diagnostics from the Pegasus Utility.
