Build Your Own 100TB NAS in 2025: Complete TrueNAS Storage Guide
techlife.blogThis 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.
I think I agree that this was 100% bad AI generated.
The 100TB Build (~$2,500) is full of errors. The math doesn't add up as presented, the HDD prices are for used drives, and it confuses RAIDZ1 and mirroring together as "five drives as two mirrored pairs + spare = ~80TB usable."
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.
Not to mention the pci-e card with contacts on both sides.
Step 1: have $10k in disposable cash sitting around.
The rest is gravy.
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.
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.

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.
I just bought a QNAP. I'm a happy customer.
AI slop.
