I'm a photographer and graphic designer, so I have a lot of large files that I need to keep backed up in a RAID. I don't need video streaming or camera feed or features like that, but I do need ultra-reliability and security. Not my choice, but the cable modem (1200Mbps plan), router, and APC Back-UPS for them are located on a closet shelf with hardly any ventilation. Would it be advisable to place the NAS in there with them or do they create a lot of heat?
What NAS housing is recommended, and with what drives? I've looked at WD and Synology, and I am leaning towards this one: Synology 4 bay NAS DiskStation DS920+ (Diskless), 4-bay; 4GB DDR4 and adding m.2 drives for cache acceleration as well as probably 2TB SSDs for storage. Is this setup recommended for my needs? Otherwise, what else would you recommend?
What SSDs are recommended? I know the WD Reds are good, and the Seagate IronWolf NAS also seem good, though some reviews are not too great.
