Hey Everyone,

With SD Cards coming so far down in price im finding 64GB SD Cards for 30 bucks and have been contemplating moving my DVD Archives to SD Cards and just using them for Archive Purpouses from here on out.

What i'm wondering is whats the shelf life on these? If they aren't being used except to retrieve a file from time to time how long do you think the data will stay in tact? I can store 16 DVD's worth of data on 1 of these things which would go a long way for storing all my video files. 

Just wondering if making this move would be a good one. It would definately make my Archive take up much less of my shelf than this huge wall of DVD's lol.

As I understand it, the main issue with the longevity of SD cards is with limited write cycles (that is, data can only be over-written somewhere around 100,000 times on modern cards before failure). Other than that, it seems to me they would actually be more reliable than DVDs for storage. But then, that's at least partially a guess. EDIT: Actually, what I'm seeing after a brief survey of the web is that you can expect an SD card to retain its charge for about 5 years. CDs (not seeing DVD data at the moment, except that it's not as good as CDs) should last about 10 years before deteriorating. So, as long as you copy the data to new SDs every 4 to 5 years or so, you should be good.

5 years from now there will probably be terabyte SD cards for 5 bucks in the bargain bin ;).

Why not use an external Hard Drive. Much More Space for a better price.

I have enough hard drives floating around and I really want something quick and easy. Plus I can store 9 SD Cards in the same size as 1 DVD case.

It's hard to say really. Unless you're going to use archival grade dvd's or cd's I can't recommend using either. LG has a new technology called "m-disc" that I would use. Outside of that, with how horrible the quality of modern cd's and dad's have become, I'd stay away from that. Between the two I'd go flash.

Well, I know I gave you a chuckle with the fact I have an old 256MB one. =D It is around 8 years old and had about 200 writes to it for saving my word docs of writing I don't want to lose. It still works well. Hopefully, the bigger ones are as good a quality as the now ancient ones, but if they are on par this should tell you they last longer than they say, but like you said, you can get bigger bargain ones in 5 years anyway. =) As a silly side note - the 16GB is just 0.75GB too small to back up the .dat file for the beta, soon to be live, version of GW2. Just saying because I know you were SLOWLY DLing all that back on your computer yesterday after the "Fun" you had on Monday.
