This article was pretty low quality and seems to have been written by AI. It might be better browsing r/datahoarders or a similar online community to find some advice on building a 100TB+ NAS.

Very first picture even looks like AI

I suspected this as well. It took me a bit to find confirmation, but the weirdly merged WD drives give it away.

Step 1: have $10k in disposable cash sitting around. The rest is gravy.

I spent $2550 on a TrueNAS setup with 3x22TB drives, so 40 TB usable after setting up ZFS. The case can hold 8 drives so I could go up to 120TB usable for an additional $2000 at $400/drive. Building big storage servers is actually much cheaper than you think nowadays.

Link to the case?

You don't need nearly that much. 26TB factory recertified Exos drives are $360 a piece on Amazon and a 4-bay UGREEN NAS is under $500, so you can do 100TB for under $2000.

More compute, redundancy etc. of course adds cost but even with RAID1, brand new WD Red drives and a PC build, you should be able to do under $6000.

Yeah I think that value prop' just got obliterated by RAM prices sorry.

You don't need a lot of RAM to run TruNAS. 16gb should be sufficient unless you are planning lots of VMs.

16GB is _not_ sufficient if you have Jellyfin or Immich or similar and a lot of media you want to scroll through quickly; I've found I need a lot of ZFS cache for that to be as responsive as I want, even with SSD storage.
