the media u choose is according the needs. If it’s for important stuff, you will buy and use expensive good media (price not always seems quality… for example TDK can’t garantee their dvd (i received a mail about this from tdk))
if u make a backup on dvd and only need it in 5 years, probably the data are not so important. Unless Photo. But with photo buy good cdr and burn them on it.
That is a thing that i noticed. I’m one that try to keep all that i can (games, films,…) after a few years i see that i never used the most i kept… So i threw most in the bin cause i needed room for other things. Life is changing and what is important for u today can be totally different tommorow. And most of the time in the informatic field… In the future, we will use new technology and so our good dvd (now) will be crap tommorow. So you always should remember that most of the back up u make now will go directly in the trash bin…
3.If you make film copies and you are a real film lover, you will buy the dvd because it will always (for the moment) be better than a copy. I usually make copy for my kids so if they broke the dvd, no prob… I keep the original. I have to add too that in my country personnal backup copy of game, cd, dvd are permitted if we own the original and if it’s only for our personnal use.
if u want quality, forget the speed. Unless u have a good burner and good media, the result will be worse.
media compatibility change with firmware update. So that’s not fixed.
all what is recordable degrades with the time. Unless u put it in an anaerobic athmosphere. Actually the way your media degrades depends on its primal quality, the way you stock it (temperature, in the sun or in a box,…),… So data that u want keep, should be writen over and over on new media…
So, by thinking a little, u see that normally the way and time we use a media is short to mid term, not long term (most of the case). U will so be interrested by the media that gives a good mix between price and quality related to time and actually a burner that can burn it correctly.
In that case according to that both drives are liteon, i should choose the one that use the most recent technology. You will have more room to progress.
