Wait, aren't waterproof, shockproof, freeze proof, x-ray proof, and anti-magnetic all just standard properties of flash memory?

I work with on projects with the NGS (National Geodetic Survey). On certain types of projects with aerial photogrametry, they require GB of data to be physically delivered to them on a HDD. They specifically state NOT to send via USPS becuase they irradiate packages, which can damage the data on magnetic HDD's... Myth? I dunno. perhaps the power of the USPS radiation is stronger than an airport X-Ray, because the USPS is trying to kill biologics with it, not inspect the packages per se?

Yeah, but that is HDDs, I'm talking flash memory, all those features are features of flash memory already.

Well you can test those elements on any of your old SD cards and see if it stands them.

I know a guy on the corner of my block selling the same cards, but if you freeze, heat, shock, or put a magnet near the cards, you void the warranty.

newtekie1Yeah, but that is HDDs

Yes, I think I pointed that out. Sort of rambling off topic.

Sure, but standard SD cards certainly are not water-, shock- and freezeproof.

But X-ray proof? :rolleyes:

Yes standard SD cards certainly are water shock and freeze proof, they are x-ray proof too. I've tested every one of those, these are just properties of flash memory, particularly SD cards that have no real circuitry in them. I've gone swimming in Lake Michigan with SD cards in my pocket, I've left SD cards sitting in my car during the coldest days of a Chicago winter, I've dropped SD cards out of 10 story windows, and I've sent them through X-Ray scanners at the airport, they've survived them all. Flash memory, particularly SD Cards, already have all these properties, they are some of the main advantages of flash memory.

The only thing I can kind of see where is waterproof, since most SD cards do have openings that water can enter. However, the water doesn't cause any damage to the flash memory, if you let the card dry out(what I did when I forgot an SD card when I went swimming) then it will continue to work fine. But I'm guessing in this case they have sealed the cards so water can't get in at all, but I've seen other SD cards(and pretty much all MicroSD cards) that are sealed as well and they don't even advertise as being waterproof.
