Lifespan depends on the same factors we’ve mentioned. Others last over thirty years (pull out an old music cassette from the 80s and give it a shot-if you can still find a cassette player-and listen for yourself). Some have been known to wear out quickly due to excessive use. Since cassette and magnetic tapes are very similar, their lifespans are also about the same. And it’s important to note that tape is more susceptible to wear and tear if used frequently.
A more realistic lifespan for magnetic tape is about ten to twenty years. That means you must store magnetic tapes where both humidity and temperatures are stable. The problem with that number is that magnetic tapes only last that long under absolutely optimum environmental conditions. Some manufacturers claim that tape can last up to thirty years, making it a suitable medium for archiving. Magnetic Tapeĭata loss in magnetic tape happens either because the media loses its magnetic charge (any magnetically charged storage medium will eventually lose its magnetic charge and subsequently its data) or when the layers of the tape start to separate. Let’s look at the various media in use today and what you can expect regarding lifespan. The only sure way to protect data is to employ the 3-2-1-1 backup strategy and invest in a backup and disaster recovery solution that meets your requirements. Lifespan depends on everything from environmental factors to usage rates to component quality and manufacturing. Whether it’s under warranty or not, all bets are off, and any storage method can fail for several reasons. Remember, just because a manufacturer claims a media device will last a long time doesn’t mean it will. You may have asked yourself how long your favorite storage method will last. And new storage technology advances will continue in concert with computing advances-overcoming quantum information storage challenges is one example-so it’s more than likely we’ll still see significant changes in data storage in the future.īack to today. While each may have its advantages, nothing lasts forever-including data storage devices. Of course, these storage technologies have also been improved over time. While we’ve made tremendous advances in data storage technology, tape and disks are still widely used, along with newer data storage formats like flash.
Magnetic disks took four more years to arrive on the scene with IBM’s RAMAC 305, the world’s first computer based on then-new hard disk drive technology. Then, in 1951 UNIVAC introduced the first tape storage device for a commercial computer, offering relatively low cost, portability, and unlimited offline capacity. It used a cathode ray tube-much like an analog TV picture tube-to store bits as dots on the screen’s surface. The first high-speed, entirely electronic memory was developed at Manchester University and tested in 1947. Digital media has been with us for a very long time.
