NAS that is capable of transcoding 4K to multiple devices

I’m looking to set up a NAS that is capable of transcoding 4K to multiple devices at the same time (potentially 3 phones), that can utilize at least four of these 8TB WD Red drives I’ve acquired from the Best Buy WD Easystore deals.

I originally planned on getting a Nvidia Shield TV with a basic NAS, but now it seems the Synology DS918+ may be the best option.

Is this correct, or do you have a better suggestion? Also, what RAID should be set up? I’d like to have a recovery option if one of the drives fails.

Lastly, I love the idea of expansion, which the DS918+ is capable of.

The DS918+ is a good choice. It might do 3 transcoding streams with simple 4K media files. But Synology suggests it would be up to 2. If you don’t want to risk get WD PR series or Qnap i3/i5/i7 x82 series. Nvidia Shield TV is a very powerful solution which would work with something simple like J series NAS.

For a 4-bay NAS most recommended, RAID is RAID5 will allows one drive failure. RAID6 would be a little overkill. Unless you do expand up to 9 drives. Then you can switch the RAID type without wiping any data from the NAS.
