How long will data last? (Hard Drive, SSD, DVD, M-Disc)

[@techindex1]

How does the lifespan you’ve got from your storage methods compare to the averages mentioned?

[@himanshu9665]

I learned something new today thanks!. You deserve a lot more views, ifound you in my fyp so hopefully a lot more do!!!

[@techindex1]

Thank you! 😊 I’m glad you found it interesting!

[@KamaradeKriska]

It's a shame you don't get as much views as you deserve! Plz keep up the good work, some day the yotube algorithm will pick you up!

[@techindex1]

Thanks so much! I really appreciate it!

Exactly channels like these should have minimum 1m subscribers and 10m views

I have stored my photos & videos on M Disc which has 100gb capacity & is Blu-ray

[@ianmoorcroft3689]

Great vid very interesting.

[@techindex1]

Thank you!

I have plenty of portable usb hdds, sd cards, a desktop two 1TB ssds, and a couple of large zip cases with burnt dvds. For alot of storage I'll probably try and get hold of a nas or das set to basic mode (that has a tray design) instead of trying to cram hdds into my pc case, and a usb m disc bluray writer for small backups. Some people do seem to have problems with burning multi layer blurays though. Over the years I'm less trusting of sd cards given they can sometimes corrupt easily, no matter which brand, and will now stay away from portable usb hdds given one drop or sudden movement of any non rugged drive can render them useless.

[@techindex1]

Hadn't heard of the issues people were having with burning multi layer blurays, do you plan to consolidate your storage in the future or keep things separated across several storage methods?

[@MrVidification]

@@techindex1 Everything as one, organised in a local 4 or 5 drive cloud nas or das should be enough, with copies of only the most valuable data I wouldn't want to lose on a few m discs and whatever else I have. A backup good brand bluray m disc player or two will no doubt also come in useful in future. Regarding longevity of older storage, my half decent branded discs such as verbatim dvds, I have had no issues with stored within a zip case, many over ten years old. The failed cds and dvds have been one or two cheap discs, usually supermarket unknown brands where the data at the top flakes off, and you are left with a clear disc. I recently also managed to get hold of a usb iomega floppy drive which was able to run on win 11 and read my old disks, which worked without issues despite being close to twenty years old. I only ever managed to get hold of a handful of those as they were on their way out at the time. I won't be needing that for backup anytime soon! I am high skeptical of the longevity claimed by m disc, but it's better than nothing or expensive LTO. I expect ssds will also evolve into something superior over time, or replaced by a new format. The layer writing issues with bluray or m disc seem to generally relate to specific models of writers. There's a possibility it could also be tied to the software used or windows itself. LG and Asus pop up alot in reviews relating to this, seemingly sharing the same manufacturer, and no doubt the same goes for all the generic made up brands out there

Geez I have never heard of m disks. It certainly beats tape archiving which is what is used as one of the most reliable archiving medium. I will check out the link

[@techindex1]

I only heard of them recently too! I will be transferring some data to M-Disc in the near future

[@valcaron]

100GB maximum capacity = annoying when backing up terabytes

[@JohnUsp]

SSDs lost data after 1 year if off.

[@truth-12345.]

I subscribed.

[@techindex1]

Thanks I really appreciate it!

[@mohdfaizal2953]

How about micro sd,thumbdrive sir??

[@techindex1]

Likely around 10 years each but this will be less if they’re frequently written to 😊

[@stefanf6495]

Though physical data retention spans are important, the real challenge lies in the (binary) data formats used to encode your documents / pictures / ... Even after as little as 20-30 years there might literally be no software available to read your specific format. There are efforts in the right direction addressing this issue (like PDF/A), but the vast majority of formats are either not documented/specified enough or even proprietary. So, if you want to make sure your investment into 1000 year data retention bluray disks is well spent money, better stick to uncompressed .txt and .bmp files.

[@techindex1]

Great point on the software/ file formats compatibility, this is something rarely considered!

[@stephenjones5304]

Thanks. I have been using the open-source DjVu format, which is a bitmap e-document format that is cross-platform and that works with text and images. Almost no one uses it or even knows about it. It was the format of choice to preserve the decades of pages of The Rolling Stone Magazine, Playboy, and The New Yorker Magazine about 20 years ago. It has been around for about 25 years, is a fine PDF substitute, and there are still viewers for it. You can upload a PDF and some other document formats of less than 30 MB to any2djvu and see what you think. The format also offers a customizable OCR program There is also a free program called pdf2djvu. The DjVu platform is like an alternate universe! Its creators have shown it offers about 50% better compression of images than standard jpeg does. But here is the thing: I submitted a request to the Library of Congress to include DjVu specs in their ebook format preservation program, but they said no because it was a rarely used format. Not a good way to preserve information. At the same time, if you do enough research, you can find programs like DjVuLibre, DjVu Solo, WinDjViewExtended and DjVuToy that allow you to use and to play around with the format. A more recent addition is the program called minidjvu-mod. These are all free programs. Most have source files available. The minidjvu-mod program has often offered better compression than even the commercial version. Check github if you are interested. There is hope.

DVDs become useless shortly jejee

[@techindex1]

A lot of them likely will in the next few years unfortunately!
