Best plex transcoding NAS +fastest NAS 2018

I need to speed up my transfers speeds between my NVMe thunderbolt 3 pc set up and my future NAS [plex server] I thought about 2 scénarios : 1 – 10gb networking for my pc and NAS without Thunderbolt support [ds3617xs cooked up with ISCSI files system using Seagate NAS pro 12tb drives] 2- using a NAS thunderbolt 3 Unit ? Question: are large files sharing with Thunderbolt 3 and 10gb network faster than 10gb networking only NAS [ds1817] Do you Still think that ds3617 is the best solution for hardware plex transcoding scénarios in 2018? Despite ds918+ and his native NVMe SSD cache support?

Not much has changed in 2018 apart from 1 new NAS from Qnap. TS-877 comes with a really powerful processor which performs quite similar if not better than DS3617xs. It was tested with 4K H265 10bit multimedia files transcoding on Plex. And is performed insanely good. If you need Plex transcoding NAS these two are the best ones. I have listed alternative which will also do the most of the things regards to transcoding, but also will offer you the fastest data transfer speed what desktop NAS can offer today.

The fastest NAS available in the market is still DS3617xs with a second place taking Qnap TVS-882ST3 . The decision is made by looking at both – write and read speed at what selected NAS models could perform.

What can I connect to a NAS?

Wireless Speaker Sonos

The great thing about Sonos is that you don't need to pay for music subscription service. With the cheapest NAS at home like DS115j or any other, you can have your backups done for all of your devices and still use your network drive as a Sonos music library. Sonos will connect to your NAS via your network and let access your provided music library. If you have little more of IT knowledge, you can even set up your Alexa or Sonos with Alexa built in to play music on your voice commands ("Alexa! Ask DS Audio to Play Music!").

Casting devices

Nowadays it is so cheap to upgrade your old TV and make it smart. All you need is Google Chrome or EZcast alternative plugged into your HDMI port at the back of your TV. Now you have great functionality added to your TV to send a video file directly from your NAS to a TV. No need for wires and chargers and other mess. You can use your phone as a remote to go to your movies or family videos and cast that content on your TV during family or friend gatherings.

It gets even better! If you want some more entertainment and all previously mentioned functions - nVidia TV is a great thing to get. You can use it for playing games and watching movies from your NAS. The greatest thing is - shield TV does video transcoding.
