In historical instances, when films and music have been saved on tapes and computer systems used floppy disks, we have been advised that magnets have been mainly the satan. Even watching VHS tapes again and again would finally trigger them to lose all their info. That’s as a result of the tape and the disks themselves have been magnetic. That’s how the information was saved.
Now, although, this outdated warning has turn out to be a modern-day fantasy with the digital reminiscence playing cards we use in our DSLRs and mirrorless cameras right this moment. But it surely seems that no, magnets can have zero impact in your reminiscence playing cards – even REALLY highly effective ones, as confirmed by Braniac75.
The above video was truly posted final yr, but it surely popped up on my advised feed final evening and I had a goo watch. Our host walks us via his course of for testing, which entails inserting recordsdata on a PNY 32GB microSD card, creating MD5 checksums from them after which subjecting the cardboard to varied ranges of magnetic torture to see if it has any impact on recordsdata in any respect.
And shock, shock… Nope, not a factor. All through all the card, even utilizing magnets so robust that they actually have a warning label that exhibits any person’s hand being crushed between two of them. Oh sure, and one of many strongest AC electromagnets on the market – one which many people deail with each day – an induction hob.
Braniac75 has additionally executed comparable exams prior to now with mechanical onerous drives which resulted in a bodily failure of the drive, in addition to SSDs that just like the microSD card got here out the opposite facet fully unscathed.
I hear the reminiscence card magnet fantasy posted at the least a few times every week in Fb teams, and I all the time must chortle as a result of there are fairly a couple of reminiscence card readers on the market which are magnetic themselves, so as to have the ability to stick them to your pc case or stack them or no matter. I’ve bought two of them caught to the facet of my steel PC case proper now (the ProGrade CFast/SD and the ProGrade twin microSD readers).
I feel if there was a difficulty with magnets, the reminiscence card producers wouldn’t be sticking them into their card readers.
The X-Ray factor additionally appears to have handed alongside from the movie days into digital fantasy, too, however no. X-Rays gained’t kill your reminiscence playing cards, both.
