I noticed that I'll occasionally experience stuttering when watching a movie on Plex. I eventually discovered that this happens when large files are simultaneously being written to the same drive. For instance, I was watching a blu-ray today, and then the WHS add-in for WMC started transferring over a recorded TV show to the server, making the movie unwatchable. All videos are stored in a pooled Flexraid array on my WHS 2011 machine, mostly on WD Green HDDs.
Is there a better way to deal with this? I suppose I could just set up a different drive for recordings, but I like having everything on my Flexraid array. Is there a way to control which action gets priority? In this case, reading is much more important than writing. Or perhaps there's a way to have the WMC add-in only run late at night. Any ideas? Anyone else have this problem?
