About every two years I upgrade my Synology NAS. This time, the DS713+ made place for a DS1815. Tough the DS713+ isn’t bad at all, in particular after a memory upgrade, a faster CPU was preferred for single threaded applications like all Python apps are. Also, I needed a minimum of 4 Gbyte memory but more was preferred since Docker is a new Synology Package and more disk shelfs would be nice. I ended up ordering the new DS1815.
Some pictures from the unit, in particular the memory slot.
