The jury is out on this and there is lots of differing opinions, but some tests say 2-5 years while other, accelerated aging tests say 30, 50, or 100 years, depending on who you believe. Quality media does seem to make a difference and I believe both Verbatim and Taiyo-Yuden (Premium line) claim 70-100 years. Knock on wood. I'm sure others will chime in on this although I can tell you that I've had lots of problems with CMC Mags and Advance (MID AMR???) that are less than two years old.

-Do you believe you own your computer and shouldn't be told what you can run and do? Then say *NO* to Microsoft Vista!
-Since half the questions here involve media problems, here ya go: Only use Verbatim or Taiyo-Yuden discs (get your TYs from Rima.com, not Supermediastore or meritline). Forget the rest, no matter what "brand" they sell under. Always burn at 4x speed regardless of the speed rating of this discs or your drive. If you have burn problems with these then you have to update your drive's firmware. For double-layer discs, only use Verbatim DVD+R DL and burn them at 2.4x speed.

It depends what your Memorex really is. If it codes under DVDIdentifer as CMC, you probably won't get more than a year or two. Ritek actually isn't too bad, although I'm told the newer Ritek isn't as good as the older stuff.

@born2ride......I was fortunate to have used those Meomorex disks that coded out to RICOHJPNs and after 3 yrs they are still going strong! no problems yet..... here is a media guide for you.... use it as a list of good and bad.. it's not totally accurate but it shows a good indication of good and crappy media out there I haven't found a better list yet. I don't agree with it's listings on TDK media, but here is the guide:

and here is a good article on DVDs.... check out about DVD STOREAGE & LONGEVITY OF DVDS: http://www.videointerchange.com/dvd.htm#DVD

There is a test specification for CD-R life testing referred to as ISO 18927 that relies on a mathematical equation known as the Eyring equation. This formula is based on measurements of thermal activity that induce change in materials over time when subjected to two different stress levels, typically temperature and humidity. If the ISO 18927 method is used to test well recorded DVD+R media ("Well" meaning that the initial PIE error average is below 56, or 80% below the upper accepted spec level of 280 PIE.), then the average life is determined to be approximately 52 years, with a few discs reaching 68 years, and 95% of the discs tested exceeding 39 years. These projections are obtained by measuring the increase in PIE rates when the discs are subjected to temperatures reaching 85 degrees C. and 85% RH then measured until the PIE averages reach 280. The full test takes 11 months to complete. Discs with poor initial recordings that show high levels of both jitter and PIE fail much earlier. CD-R rates reach an average of 138 years using the same test methodology. Gold reflective layers make little difference despite the hype. The assumption of such long life is that the discs in real life remain at 25 degrees C. and 50% RH. Humidity is the killer for DVD, not heat.

Yes. All I can say at this point in its development is that Blu-ray (both BD-R and BD-RW) can be recommended as archival media only for grocery lists. They are that unstable! Reports about consumers' preference for HD DVD, the lower cost of HD DVD media and players, and the antipathy toward Sony (batteries, root kits, PS 3 delays, dropping SACD-an incompatible format they pushed vs DVD-Audio, etc.) indicates that Blu-ray does not need more problems. Once consumers find how delicate near-field Blu-ray discs are, even with hard coatings, the tide will turn in favor of the more practical alternative.
