NAS Storage

Between the lockdown and being made furloughed, I'm REALLY glad that I haven't got rid of any of the photos I've taken - yes there's (literally) terabytes and terabytes, but it has meant I've been busy and it's kept me (almost) sane.
The downside of this is where to store the 67,000+ model and client and event shoots, and 55,000+ other personal (friends/family) photo I've taken over the years - along with the videos, music, scans and other stuff you find and want to keep? Keeping these on 5 hard-disks which may (or hopefully may not) fail at any given time is dicing with life and death, so I've invested in a Synology DS918+ NAS device. Data is kept on 4 harddrives, which theoretically means that if one fails, I should be able to recover the data without any issue - just whack in a replacement drive and away we go! Despite it's other capabilities (VPN, backup, docker, proxy, DCHP, Plex media server) - it's primary use is storage - and buckets of it - or in my case, I've still got another 7tb to fill (3-4 years???) and it means I can also re-purpose another drive for backing up the core NAS files. The question is....Who wants to help me fill it? Is there anyone requiring any photographic services?
