Thanks so much. We just bought a Blu-ray player and started ripping movies to see how much storage we would need. I was looking at the TS 653D with 12 TB drives and raid 6. We can always get a expansion unit as well. Do you think the TS 653 D can hardware transcode with plex to 4k while running surveillance? The reason I am going with raid 6 over raid 5 is because apparently raid 6 is necessary if you are going with more than 25 tb of storage. This is because more drives can fail while repairing themselves because they are under a lot of stress. Do you guys know if this is true or just BS.
