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!
Personally, I recommend the lsi cards. Those things are tanks. The lsi 8i (8 internal) has been my friend for many years without fail. It does support jbod, so no raid, and I hooked a tape drive up to it too.
Tell me more about your tape drive though, I'm unhappy with mine and I'm looking to replace it
Feel free to ping me if you make the jump, I learned a lot about it. Biggest thing I can recommend is double triple make sure everything supports ltfs, it will make your life 1000% easier.
Tbh, it downloads in the best quality available by default, so I do that and dump it into my server's completed folder where the appropriate *arr will move it into the right folder and if it's a weird format tdarr will take care of that.
TL;DR no options and automated tools
Edit: although worth noting for YouTube content, the moving step is manual if sonarr doesn't have metadata for it
This is not true. All Verbatim BD-Rs (including VERBAT-IMe-000) use inorganic dyes. It's stated by several different people in the comments in your link.
One thing to keep in mind: if someone gave you a 5.25" floppy disk with this type of data on it, even if the data was perfectly readable, would you have any way to do it? You'd need to hunt down someone whos into retro technology and hope you can figure out how to decode the information. The format itself became obsolete, so even if the data would theoretically be accessible, the means to access said data may not be.
Point is, what are the chances that CD drives will be around in hundreds of years outside of a museum or personal collection? They're already becoming more and more uncommon after only a couple decades. But there really isn't a great solution to this, especially when it comes to video, because you can't just print it out.
Side note, are you sure that CD Golds are more durable than M-Disk?
Digital data is extremely short lived. Unless it's being maintained well and copied, it will decay regardless of storage medium fairly rapidly. And as you point out data interface techniques are themselves quite short lived. Storing data as something accessible without specialist technology, so plainly readable, instructions on how to build the reader and decode the data, etc.
Future technology may improve this by having historians interested in historical records wanting ways to recover it, at least.
Digital? No. You want durable, you go physical. Print the photos with real archive-quality processes and materials. Same for video and audio, but on film. Keep a 3-2-1 backup in climate-controlled environments.
If you really really want digital, the media doesn't matter, because you'll always have to migrate to current formats. Someone will have to be actively maintaining it.
Yeah, I'd say at least every ten years I've replaced all my media. Hard drive failures, tape upgrades, physical media changes, tech just moves so quickly. Even if the media survives 100 years, will we still have the tech to read it?
Afaik it's either LTO tapes or a RAIDZ array, I like ZFS on Linux for that matter. Check the TrueNAS Scale distro for example. There are different raid levels, I use raid5..
I believe you're approaching this from the wrong angle - this isn't a tech problem, this is a people problem.
save them for posterity so that it lasts for periods like 200 years and more. This allows great-grandchildren and great-great-grandchildren to have access.
Instead of trying to get media that can last 200+ years, just teach your kids and grandkids the importance of keeping your family legacy alive. This will be way more effective than any medium you can come up it. Storage technologies change but the data remains the same, the future generations should be able to gradually upgrade storage mediums as necessary so the information keeps existing.
