Price wise, well, it’s going to vary depending where you are in the world and exactly when you look. That might be obvious, but what’s less obvious is that once the disk has had its metadata queued by his media-streaming Plex server the M-disk is plenty fast enough for streaming music with no noticeable lag. That load time does happen every time you load in a fresh disk, but how often would you be swapping out 100 GB of songs? If you’ve already got a Blu-ray drive and are hard up for storage, it might make sense right now to move your music to an optical disk while waiting for drive pries to normalize. All we can say is that’s probably not going to be audio tape, as cool as a reel-to-reel would look in the server room.
