I currently have a very old synology ds115j NAS which connects via a switch to my Intel NUC just to stream movies and the like, I dont use it for photo backups or time machine backups as I’m happy paying for larger icloud storage and have important folder that get backed up. I dont need to remotely access it (away from home) and can count on one hand the amount of times I’ve done that. I’m happy either using my macbook or the NAS to download items so doesn’t need to have that functionality. It’s connected to a VPN and needs to continue to be able to.
It has a 1TB WD SATA drive in it which diskstation tells me is healthy and is 72% full, I fairly regularly delete stuff that I’ve just watched once so it isn’t bogged down with rubbish.
The NAS is sooooooooooooooooo slow, like painfully slow. So slow I avoid using it because I want to be able to click something and things happen and not feel like it’s about to completely breakdown. I dont need 2 drives so that one drive is backed up by another, if it were to break it would be annoying but not catastrophic, it’s nothing I can’t replace.
Budget? Well secondhand would be fine, probably no more than £200 for the NAS itself and then I can get maybe a SSD separately to go inside it.
