The home-writable CDs involve alteration of a dye layer, and were never intended for long-term storage. That's in contrast to a manufactured music CD, whereas the pits and lands are pressed into the reflective layer.

MDiscs is where I think I have my bytes nowadays.

Wow! Nice vídeo!!! Congrats!

Great video 👍

Before even watching I'll make a quick comment - properly stored, high quality CD/DVD/BR discs can easily last decades as off-line storage. I have still working CD-R's from the early 90's that were used for drive backups, same for DVD's from the 00's. And I have no reason to believe my current batch of BR backups will not last just as long.

Nice sharing

What will happen to Voyager 1 and 2?

Fantastic video. Is there a part 2?

Just keep copies of your valuable information on multiple disks, usbs, hdd's, sd cards etc... Keep them in a cool, dark, proper temp room and you can even go the extra step and write the md5 checksum of a file and how many bytes so you can find out if the files changed in any way (write it on a piece of paper)

While I agree that long term data storage is a serious issue, I think the comment about a stone inscription lasting 10,000 years to be a bit disingenuous. It may last that long if there are no earthquakes, strong winds, water running over it, tree roots tearing up the stone or defacement by enemies.

Thats why tapes are great

I have disks from 2008 and they still work, they are DVD-R. CD-R thhe layer is on the top side and gets micro holes even inside the case. Do you want proof of this? Hold the CD-R and point it at the ceiling light you will see the holes. DVDs are brand quality dependent, so the bad quality ones the record layer will get stains and data will be lost on these stains, this occurs around the disk edges.

I Guess that's Why some servers were using backup cassette tapes My Dad has audio tapes from 30 years ago and there still not too Bad the Good Old tape might be the best option😊

Bluray HTL Discs don't have this problem. So Bluray Archiving is the way to go to Cold Storage Backup Data in 23.23 Rar Files.

I have a lot of CD I buy some 1984 and still fine so I don't know what this guy's talking about

CDs can be very reliable if stored properly. Just get good ones and store them properly and good luck to you!

What kind of medium is then actually be reliable for storing Precious Memories for Longer time say, 30 years or more?

I'll print my data in bits on paper , zeroes and ones

Hardrives are a good choice if they are stored in a safe place

How can the quality of dots and dashes become worse?

Don't watch the video: M Disc it's the solution!

That is 100,000 cycles for MLC. You will NOT get that from QLC!!

M Disc is the answer. Look it up. A blu-ray M Disc can store 25-100 gigabytes for up to 1,000 years affordably

HDD is the best we have at this moment, of course, make backups in another HDD and also in the cloud.

Many people are getting tattoos

What a pile of hogwash and clickbait. I can respond in several ways: 1. In the broad perspective, digital storage media are not developed with the expectation of lasting for millennia. That doesn't mean they couldn't be. It's just not the priority right now. At present we need to get costs down, capacity up, and more reliability. This is not some dark conspiracy, or some siren song of fake progress. It's perfectly rational. You just need to understand the parameters you're dealing with. 2. Digital data can be backed up and preserved, far outlasting the original media. This is very easy by now, and easier all the time. Media lifetime matters, but less than human carelessness. 3. My own experience disagrees greatly from the claims made in these interviews. Yes, I have seen defective discs. As said in the video, these generally appear in the first year or few years, and BTW they're usually evident just looking at them. The rest last a long time. It's not 15%. I doubt it's over 1%. Those talking heads in the video should stop buying crappy discs. 4. I started burning CD-Rs in 1998, burning maybe as many as 2000, until 2011, when I went to USB hard drives and flash drives for archival. Not once have I seen a clear case of age-related data loss, except for those few defective discs. 4. For archival storage, you really need to verify your data. The OS SHOULD do that for you as you copy, but in my experience you can get burned. Use some kind of checksum tools, and do it consistently. A PITA, but well worth it. 5. Longevity of flash drives is still TBD, but I'm not worried. Again, keep refreshing your data, and using those checksums, and you can sleep well. 6. Long-term readability of data formats is the real worry. Going from discs and tapes, which, face it, were a real PITA, to solid state and USB, restores quite a bit of sanity. Geeks just love to come up with new formats, but at least now it's basically just file formats, not media formats, and it's easier to maintain control over what file formats you use.
