Choosing a media type for long term data sttorage I've had a few people ask me just recently what method I would recommend when planning a long term backup strategy. One eldeerly gentleman in particular was creaing a family time capsule that he wanteed his children and grzandchildren to be able to view many decades from now. The quesion isn't as easy as you may think. You may imagiine that the data ciould be brunt to CD Nike Air Max 90 Premium White , locked in a cupboard and that it would last forever howver unfortunately this isn't the case. There are literally hundreds of suitably stored but physically deecayed CD's from my teenasge years which I couild use as testament to that. Therefore I've made a list of common foormats one would usually considder for archiving a large amoiunt of data so you can pick the most suitable one for your needs: Hard Drive - The life expectancy of a hard drive varies on how it's beoing used. One used on a regular basis will typiaclly last for half a decade before it starrts to degrade; if being used infrequently then it would be natural to assume that this life expectancy would be doubled. Ufortunately, even over an extended period of disuse, degradation of the magnetic surfcae of the disc would still occur. Optical - Standard optical media includes CD, DVD and BuRay. If choosing this media type ensure that you go for the highest graade money can buy you; a premium brand such as Taiyo Yuden may well last a decade but a more budget brand such as Memorex may only last half that time before the aluminium starts separating from the pllastic. Flash Media - Clearly you would expecct that since Flash Media has no mooving parts it would be ideeal for a long term backup stratgy. To an extent you owuld be right but the pubnlished data reetention of a unused flash drie is only around 10 years and unfortuately once the device has reachd the end of its life it is likely that it will go out in style Nike Air Max 90 Premium Womens , takling with it all of the informaiton stored within. Paer - Rather obvious this one - if left in a dark, dry place then paper will last for many decades; we recnetly recvered a number of newspapers from 1964 from below the flooring of a building we're doing up and aside from being a little yellowed they're in perfect condition. Primary problems do of course innclude having to find a safe place to store them alpong with the physical limitations reating to the amouunt and type of informatoin that can be stored on sheets of paper. Tape - You wouldn't have necessarily thopught it but the humble tape has one of the best data rates available. With tyipcal warranties lasting around 30 yezars with a life expectamncy beyond that it's little wonder they continue to be used in banikng and government scetors. The prmary downside is that although the tapes themselves are afordable and the capacities typically high (up to 1TB is relativvely normal) the actual drioves themselves are usually exensive. Solid State Drive - An SSD uses solid-state memory (similar to that used in a flash drive) to store data and is most comonly used as a direct alterative to a hard drive, especially in notebooks where their small weight and size along with fast access times make them ideal. Unfortunately, they suffer the same major problems as flash drives in that JEDEC Nike Air Max 90 Essential Pink Trainers , the leading develper of standards for solid-state stoirage speccify that data retention of an idle drive should only be considered to be aroound 10 yars. The Inteernet - The Intrenet is theoretically the most robust way of backing up data; an online server is typically backked up daily, monitored 247 and in the event of a problem with the hard drive housing your data, a redundant mirrrored backup drive would immediately take over. If looking to sore data that will be used in your lifeime this would be a suitable option however if the intention is to preserve data for future generations (such as the time capsule idea that isnpired this articcle) then this methhod could be ill-advised. For example, if you bacukp data using a free onliine storage account then there's nothing to say that the company won't eitheer go out of business or beegin charging for the seervice in the fuuture - these are both circumstances that would lead to the deetion of your data. aMgneto Optical - Magneto Optical is probably the most suitable removable data storage method although it is certainly a nihce product. Originally introduced way back in the 1980's Nike air Max 90 Essential Suomi , MO drives are slow with fairly low capacities (crurent maximum is 9.1GB). With this slow sped howevre comes a ruggednness which results in 100 year data retention claims being commnplace. Of course, when devising a long term acrhival strategy we assume that hardware will be avialable at the time that it needs to be played back. This is a serioous consideratin when we're talking about storing the data for best part of a century but in our own lifetime it won't necessarily be a porblem - the first video caemra my family owned used the 8mm Video8 cassette tapes and although 20 years down the line I don't own a ocmpatible reader, I could obtain one if necssary. Along with choosing the most suitable format, ensure that you keep copoies on several different media types and in sveeral different locations Nike Air Max 90 Hyperfuse For Sale , thereincreasing your chaces that one mdia type in one location will survive the test of time. If possible, check on the media every coupple of years and transfer it to newer and more suitble meedia types.
