SA6400

Just go with the latest 7.2 from the synology download site. 7.3 will work on the SA6400 with a modified kernel. Honestly not worth it at the moment - 7.3 doesn't offer anything significant over 7.2.

I went for the SA6400 with a new computer build with an i5-13500 and it's running great. I've got Proxmox on top and Synology DSM in a VM with latest Arc Loader beta and no issues so far.

Updated the Synology model to SA6400 and everything works beautifully, including read/write caching. Wish I had looked into this much sooner - the full functionality of Synology DSM on the hardware of the Ugreen Nas is just awesome.

Choose SA6400 since it's based on the most recent kernel. And IMHO it will be best to install it baremetal or in Proxmox or similar. When installed properly the system is indistinguishable from an original Synology box. And has everything that an original Synology box will offer you - easy of use, m

Running the same SA6400 on a NUC8 with a USB DAS attached. Everything works as it should, including sharing external links on the internet, Plex, immich, synology drive. I attempted to update at one point, but the “NAS” didn’t boot into the OS anymore. Had to do everything from square one. I wish th

I've used this site for my proxmox DSM setup. https://blog.nootch.net/post/poor-mans-synology-nas-on-proxmox/ With ARC, You can change the model anytime the hardware suits you. I was using DS3622x and realized the SA6400 uses a more updated kernel so I changed the ARC boot drive in proxmox, selected
