Who are we?
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). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

What I know: https://raid.wiki.kernel.org/index.php/A_guide_to_mdadm No need to do hardware raid, mdadm is great. I got an HBA card off of art of server on eBay, and have ungodly amounts of disk. Also, am ungodly power bill... You can stick regular SATA drives into a SAS Bay, but not SAS drives into a SATA bay. Some HP equipment is bitchy about non -HP drives, cards, etc. I saw a fair amount of "Do RAID 6!" But I found on my hardware that RAID 5 and a hot standby was moderately faster. Try not to mix drive sizes, it messes things up and wastes space. Have fun!
