Data Hoarder

We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

This is why you gotta test your stashed drives yearly. This drive surface was already having issues after just one year (alien.top)

What are you using for a server and how do you manage it? I need something at least 500+TB, but I've yet to find something that's reasonably cost effective and easy enough for a dumbass like me to manage (hardware more than software).

My average cost per usable TB is around $11 per TB, but most of my drives are smaller used SATA/SAS drives. My main pools come out to about 450TB of usable storage.

Edit, Copy paste from the post I never got around to making.

Main Pools 2023, are on 24/7/365 - 360-420 Watts.

I use 3 UPS units to protect them.

Name	Usable TB	ZFS	vdev	Drives per vdev	Drive size	Estimated total cost	Content	Notes
Main	65.90TB	RAIDz2	1	8	12TB	$960	Content	New drives
Main	76.50TB	RAIDz2	1	8	14TB	$1200	Content	New drives
Main	87.86TB	RAIDz2	1	8	16TB	$1120	Content	reconditioned drives
Backup0	176.91TB	RAIDz2	2	12	10TB	$1500	Backup	used + new drives
Temp0	12TB	EXT4	1	1	12TB	$120	Temp	new drive

Main pool - 261.26TB, This is all 1 pool, but I broke it up on the list since I use 3 different drive sizes.

Total usable TB : 450.17TB

Total Cost : $4900 / 450.17TB = $10.89 per usable TB, not bad considering the amount of drives were purchased new.
