If you feel that your video stream is always buffering, You might need to check the network first. If  the network performances OK, then you might think to move the PLEX from STAT drive to SSD drive. Here are steps to move the PLEX application to a different location on QNAP: Step 1> Stop the PLEX service Step 2> Ssh into the QNAP Step 3> Locate the current location. For example: Mine is under /share/CACHEDEV2_DATA/.qpkg/PlexMediaServer Step 4> Copy the entire directory from the current volume to the SSD volume cp -rp /share/CACHEDEV2_DATA/.qpkg/PlexMediaServer  /share/CACHEDEV3_DATA/.qpkg/ Step 5> edit /etc/config/qpkg.conf and search PlexMediaServer and change the volume name from old one to the new one. For example:
