I added another 32GB to my 923+ recently. Looking around, I found that speicher.de (German shop specializing in RAM) offers RAM for specific Diskstation models beyond Synology's specification, and they guarantee you that it's going to be working! (They call this "overRAMing"). For the DS920+, you can find the offered RAM sizes here. I have had zero problems, my NAS now has 36 GB RAM, shows no errors or warnings, and I'll probably upgrade it to overall 64 GB sometime. And my 218+ runs with 10 GB RAM since several years without any issues or warnings. Rather the opposite: in both cases, the difference was tremendous, it felt like entirely new (much faster) devices. I can highly recommend.
[Edit: I changed the German links to the corresponding ones of their English site]
RAID is not a technology designed to manage backups… it is designed to either support speed or reliability. If you overwrite a good file with a bad one, then you have a very fast or reliable copy of a bad file.
Yep, I understand that. I didn’t know if RAID 6, having parity bits, would be able to repair a file from that data. I figured being RAID would protect it from corruption but apparently not. I didn’t overwrite the file with a bad one, it just stopped working.
Just when I’m on the fence ton replace my ds214 play. Hoping for better performances for the surveillance station and the docker capability that I currently lack.
DS224+ will likely give you really good performance based on what you mentioned. Although the max RAM (6GB) could potentially be a concern if you run too many containers
Thanks for the feedback :) Container-wise it will be related to smart home integration largely so hopefully things like homebridge aren’t too resource hungry.
One reason I thought of this was that it’s taking forever to manually copy files from the corrupt volume to an external hard drive anyhow, and I trust the external drive less. It’s honestly not even that much data – I can’t imagine internally copying from one drive to another would take longer.
