Review: Best in the Industry NAS - One of the Best in the industry feature rich reliable, expandable and cost effective high performance NAS
Review: Costa quello che costa... ma di un altro livello! - La possibilità di espandere il prodotto con Cache e Ram aggiuntive e il fatto di averlo preso al prezzo del fratello minore con 6 bay, fanno di questo mio acquisto uno dei migliori di sempre. Sono passato da due NAS (Synology 4 bay e un 2 bay per la videosorveglianza) a questo modello, migrando con una facilità unica gli HDD dei vecchi NAS a questo... Quindi dedicando i 4 dischi a storage pool e 2 gli altri dischi a videosorveglianza in un altro storage pool sullo stesso apparato... con un avanzo per futura espansione di 2 HDD. Unico accesso con tutti i servizi. Quello che volevo! Prodotto consigliato se si vuol più di un semplice storage, fa un pò di tutto e permette anche di implementare delle VM ed espandere la versatilità del NAS. Ho inventrato in un unico apparato Storage, Backup, Videosorveglianza, Domotica di Casa, Server di Posta, Active Directory, Media Server e Hosting... e può fare anche di più.

### ⭐⭐⭐⭐⭐ 8 bay's seems to be the sweetspot for me
*by G***N on 8 December 2022*

So this is my 3rd Synolyg NAS. I have a 4 and a 12-bay and the reason for the purchase of the 8-bay was to move to a newer supported platform since my 12-bay has reached end of life and does not receive new SW updates. With today's sizes of hard drives an 8-bay works out great for me. Having 5 disks in a SHR-2 configuration gives med enough space and I also have 1 disk sitting on the shelf if I need to replace any of the disks in the future (this actually happened for the 12-bay last month that I needed to replace a disk and had it done in minutes instead of days if I had to order a disk). So this leave me with 3 empty bays. I'm planning to run my cameras to the NAS in the future so two of the bays will be housing hard drives meant for surveillance workloads in the future. I also bought a Mellanox ConnectX-3 10 GBe network card instead of a Synology branded one since it was cheaper and I needed the SPF+ interface. Some memory to upgrade from Kingston also worked even though it isn't on the compatibility list (Look at NasCompares YouTube channel and website, they have tested non Synology RAM in different models). I would recommend the Synology brand for NAS devices to everyone. They do not have the lowest price but I think it is worth it.
