Yeah, maybe DVD readers will still be around in 20+ years but it's less certain is all and might be harder to find and I suspect once stuff is harder to find, costs will probably rise a bit to (especially once they stop producing DVD drives) and, come to think of it, not only that but if computers ever start phasing out SATA ports that could be another issue as even older IDE burners are more difficult to use right now due to lack of semi-recent computers having IDE ports as a couple of my older CD/DVD burners (Liteon 24102b/Liteon 1673S) are IDE connections. granted, I have them installed on my older PC's motherboard I got in March 2006 but if that ever dies at some point they might be more difficult to use properly. sure, I realize I can use them on some level with one of those devices that convert to a USB connection and all but it's not really optimal. but I guess if reading the disc is primarily ones concern, it's passable. but I guess one could argue just use a SATA DVD burner/reader which one easily could as I still have a couple of SATA based DVD burners (Sony Optiarc 7240s/Liteon iHAS324B). but hopefully computers continue to use the basic SATA port for many years to come.totally lost wrote: ↑Fri Jan 10, 2020 10:49 pmFar as being gone in 20 years idk. You can still buy the super old tape style data readers from before i was born. In fact you can still get VHS tape players Atrack tape players and so on. Sure they are harder to find but still there. Even record players are coming back. Either way if something new comes out i will jump on that one to with yet another copy. They are not my only copy either. The HDDs will be more up to date provided i never kill all of them at once.
but when it comes to general data backup... between a hard drive and quality recordable DVD media (say Verbatim/Taiyo Yuden) I tend to trust DVD media more to reliably retrieve my data from it in 10-20 years time (even though the hard drive is definitely more convenient, obviously). recordable DVD is just a solid backup to general hard drive backups for higher importance kind of data as between CD/DVD/BluRay, while BluRay is better in the sense you can get a lot more data on there per disc vs CD/DVD, I wonder about it's reliability in 10-20 years of time as I think DVD is more proven in that regard. maybe some recordable BluRay media is solid though but I have no desire to jump on the BluRay recordable bandwagon especially once hard drives prices came way down to where it's easily the best choice for general data backup overall, especially if you got at least a copy of your important data on two different hard drives at the minimum and one can always opt for burning to DVD for the smaller amount of family pictures/videos of higher importance as an additional safety measure against data loss and 4.7GB a disc sure beats 700MB for a CD-R which is almost nothing so using CD-R for data backup is just not practical in today's world as those are a MUSIC CD only kind of thing at this point and for many years now and I could see one arguing in favor of BluRay given it's 5.3 times the amount of data vs a standard DVD (i.e. 25GB vs 4.7GB) but I have heard BluRay burners tend to fail more often(?). but all-in-all, costs are still a bit steep to get into BluRay burning if you ask me (and there reliability seems to be questionable compared to DVD) especially given I already still have quite a few DVD recordable discs from many years ago ready to use for my occasional use.
just some thoughts
