Quiet 4-bay NAS

[Enquiries]

Hi, I'm looking for a small quiet 4-bay NAS that I intend to equip with 2x6TB disks to start with, preferrably Synology running SHR. The main usage will be for hosting all sort of files but to a large degree movies, photos and music, I have an external mediaplayer so no need for transcoding really. Might run Plex. Need to be able to stream high bitrate movies that are 4k 60FPS (without transcoding) to my mediaplayer. The NAS will be about 12 feet from the main TV viewing position and I would like it to be as quiet as possible, what disks should I choose?
Thanks for any help you can give me on this.
