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)

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.
