In historical occasions, when films and music have been saved on tapes and computer systems used floppy disks, we have been advised that magnets have been principally the satan. Even watching VHS tapes time and again would ultimately 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 previous warning has turn out to be a modern-day delusion with the digital reminiscence playing cards we use in our DSLRs and mirrorless cameras in the present day. However it seems that no, magnets may have zero impact in your reminiscence playing cards – even REALLY highly effective ones, as confirmed by Braniac75.
The above video was truly posted final 12 months, however it popped up on my prompt feed final night time and I had a goo watch. Our host walks us by 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 the complete card, even utilizing magnets so robust that they actually have a warning label that exhibits any individual’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 accomplished related checks previously with mechanical laborious 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 aspect fully unscathed.
I hear the reminiscence card magnet delusion posted at the least a few times every week in Fb teams, and I all the time must giggle as a result of there are fairly just a few reminiscence card readers on the market which are magnetic themselves, so as to have the ability to stick them to your laptop case or stack them or no matter. I’ve acquired two of them caught to the aspect of my steel PC case proper now (the ProGrade CFast/SD and the ProGrade twin microSD readers).
I feel if there was a problem 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 delusion, too, however no. X-Rays received’t kill your reminiscence playing cards, both.
