Default Anyone knows what is the actual life-span of a SD Card?

Anyone out there knows what is the actual life-span of a SD Card?

Many manufacturers list their SD cards as having a life-span of 10 years and offer anywhere from 0 to 5 years warranty.....Even a giant like SanDisk would only guarantee up to 5 years......

Why are there manufacturers who could guarantee lifetime?

What is the difference between lifetime SDs and 10-year SDs?

What is the catch?

ok dude no probs ANSWERS: -
  • Why are there manufacturers who could guarantee lifetime?
  • What is the difference between lifetime SDs and 10-year SDs?
this is based with the difference in the development of card manufacturing and the type of Gates used in cards (like NAND,AND,XOR, etc) which make up memory that is dependent on using short circuits(wiring)

giants like Sandisk/Transcend/Smasung etc all use this type of memory development, becasue Sandisk dont receommend Life is that they may use a different interface with their cards which Transcend and Samsung dont it all depends on the type of techn ilogy and tactics used within the memory card development, if you read up about this or ask the comapnies they may tell you background info based with their card technology or read up about Gates on Wikpedia...

Transcend provide a Lifetime gurantee on most of their card so do Sandisk and Samsung only other prducts lower quartile based porducts wouldnt have the lastability than expesiver or newere products technology design...this is why it explains that products like the Transcend 8GB SDHC Class 2 has a lifetime warranty as its uses the new interface of NAND gates to store higher capicirty memory in such a small device... this also explains the difference with the difference between lifetime SDs and 10-year SDs becasue if the technlogy usded in different companies and different products......

actual lifespan varies according to how you use the card in excessive uses, eg you might drop it a few times may stop working in less than a year , keeps crashing becasue you dont use it proerly or store files which can contain viruses, wear and tear issues, may be defective etc different issues relate to the way lifespan varies with many card out their... but i can tell you that their is no card which wont have a issue what i mean by this is that their is no card out in a world which will not have an issue styated above like corruption, every memory card will have this becasue memeory can corrupt in differrnt ways, so that involves the lifepan issue as you have a card which keeps corrupting meaning its defective in some way where the warrant comes in handy thats why their is no catch as all technology fails sometime soon or crashes which is why comapnies have a high rate warrant polociy withy specialised products like this cards....hope that helps
  • What is the catch?

is no catch only based with what consumers or us customers in the world really look oput for as in what type of brand has the best usability, customer responses, terch advice etc which is based with what type of product you buy in the end and from what brand e.g many peoiple prefer Transcend over Sandisk becasue of the reliabilty that transcend offer onj the wide ranges of prosucts they offer...so no catch only fact that what you want in end dude....hope that helps feng thankx for the post dude hope that helps anyone else ...enjoy dudes

article on Gates Technology -
hope this info helps dudes...sorry for my spelling im Japanese really suck at english but hey im here to help no probs ...enjoy

maybe it will last longer than you want it to be..
when I bought my 256mb for my digicam years ago,
I worried if they would break and be covered by warranty.

It still works like charm, but no use..
In couple of years, 4gb or 8gb might not be that useful.
just my opinion.

so cycle is defined as removing and putting back? what if it stays in the device? is it also count for power on/off in the device or only physical removal? i never figured that out... they make it sound as if its physical... but something tells me it has to do more so with electrical O_o

you're confusing digital read/write cycles with physical insertion/removal cycles. both are limiting factors on the card's lifetime. but with digital technology, replacing it will be cheap within 2 years.
