    You can't go wrong with the Synology 923+. If you are a power user like me, it's worth to add the nVME read cache and up'd the ram to 16GB. I spec mine with the following :

    4 x 12TB hard drive - Raid 10
    2 x 1TB cache drive - Raid 1
    2 x 8GB Ram

    Very happy with my Synology NAS. I had been researching brands and models on and off for a few year and finally settled on this one as a back up for files, photos and videos and also turned into a PLEX media server.

    I had to replace my DS920+ due to sudden death. The DS923 is very bad. I was very satisfied with Synology until I had to replace the server. Many things are not working as before. Very disappointing.
