According to our NAS expert
Use the Qnap TS-251+ to save files, as a backup, for home entertainment, as a personal cloud, and more. Store your movies, series, and photos on the NAS and view them wherever, whenever with the app on your smartphone or tablet. Thanks to DLNA and AirPlay, you can stream Full HD movies, series, and music to a media player, smart TV, or console via your network. You can also connect the TS-251+ to your TV directly with the HDMI connector and watch your movies with KODI or Plex.

This NAS is loaded with functionalities. Possibilities are endless. It's not all as user-friendly as a Synology, but it can do more. The limitations are in the performance. For example, I discovered that copying from a USB3.0 hard disk went at only 20Mb/s. Using the NAS as a media player with KODI or PLEX home theater is not workable because navigating through the menus is too slow. Fortunately, sharing files with the TS-251+ is fine. On a gigabit network I get more than 100 Mb/s and transcoding with PLEX server (almost) always goes well. 1080p H265 is just barely going but 4k transcoding goes just above the cap on the TS-251+. An acceptable limit as far as I'm concerned. Finally, I unfortunately have to report that the NAS transfers the HD vibrations very clearly to its environment. Maybe it's my Seagate 8TB. This also makes the TS-251+ less suitable as a media player.

I was looking for a RAID1 NAS quite compact and facilitating video streaming; it encounters my needs

I chose this nas because of the better hardware than at the same price at the largest competitor. Now the biggest competition is in-house with the 253a type at the same price with 4k capability. The NAS is mainly used for storing photos and backups (images) of Windows and Android devices. Installing is easy, but in the beginning it is a bit of searching for what is where. It is also not very clear during the first installation which file format is used and which raid. Some work could be done on this. The NAS contains 2x6 Terra WD Red drives and they are relatively quiet. If the processor is under some load and the speed of the fan goes to 1200 1/min, the whole nas hums. Clearly audible and annoying. I solved it by placing an old sergeant (glue tongs) at the back where the fan is located. Provided the correct clamping is set, the hum can be set to almost zero. This is probably due to the plastic finish. If the reliability is not too bad, this is a must!
