I use two of these disks in a month Synolgy NAS 209. The NAS is configured in RAID1 (mirrored 2 discs). They are quiet and are very suitable for an audio or video server, similar to a desktop PC I think. This is not the supra write speed (can be the RAID 1 also), but for standard use if we do not copy tons of files per day is a great product that I recommend. No problem identified in audio or video playback.
