The system cabinet delivers rock solid performance and works well for users. Customers find it straightforward to use and easy to install drives. The build quality receives praise as a great quality product. The cabinet operates very quietly even under load with a very quiet fan. Transfer speeds are much faster, reaching about 110MB/s. However, customers have mixed experiences with network connectivity.

    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

    Le système pour lequel Synology fait la promotion, avec une suite prétendument simple à installer et à utiliser m'a incité à me lancer dans l'achat de cette suite pour la petite organisation dont je suis directeur. Six mois après l'installation du DiskStation, malgré le soutien de deux techniciens en informatique, notre petite équipe de travail et moi-même n'avons pas pu profiter des fonctionnalités annoncées, telle la supposée possibilité de créer notre serveur Web et courriel maison. En ce moment, cela se limite à une sauvegarde automatique de type RAID qui est fonctionne relativement bien, mais qui fait ralentir notre réseau.

    I had an old DS414j for a decade, and astonishingly Synology would still deal with support queries. It was time, however, to replace it, so I bought this and have not been disappointed. Setup was a total breeze and its performance is excellent. Given the limited role I have for it, it's basically bored out of its skull most of the time.... but it just works. It's quiet, it's cool (in all senses of the word) and I know it'll be reliable. Brilliant.
