Can you please decipher Micro SD cards for me?

Asked by Hawaii_Jake (30619points) September 26th, 2013

I know what a memory card is for and what the different capacities mean.

What is SD, SD HC, Class 8 or 10, and UHC-1?

I thought getting a memory card was pretty easy. Now I’m confused.

Mostly, the differences arethe size of the card and its memory capacity. There are other factors, too, but those are the two main ones. See if this helps you understand better.

Newer machines can use SDHC, which means high capacity. Some few older machines cannot and must use SD. Look at the guidebook for your machine and it should tell you which one to use. I am not familiar with the three other terms, sorry.

Your Samsung takes a Micro SD card which is pretty tiny compared to regular SD cards.

It can take any storage size up to and including 32 gb. Be careful when buying them in the Internet as I’ve read there are lots of counterfeit ones with major brand names on them floating around on Amazon and EBay.

Better to use a company with a solid reputation. You may pay a few bucks extra but it won’t be a piece of non working crap (and if it is, you can return it and they’ll make good on it)

@Buttonstc Thank you. Good to know.

There are definitely speed classes, too. If you’re shooting HD video with your camera you need a faster card. If you shoot high-resolution photos and shoot multiple shots quickly you need a faster card.

Micro SD is just the same technology in a much smaller package.

The “class” 8, 10 etc deals with the “speed” some devices don’t need the memory cards to be too fast so you can go with the cheaper and usually more reliable models like class 3. Things like high-end cameras you’ll want the best you can get. Again, be aware that many have noticed the higher class cards tend to be more persnikety about being moved around. If you get a class ten card or whatever they are up to now treat them lightly as they very delicate and tend to die.

Your mileage may vary but so far I’ve had no trouble with a couple class-10 cards in cameras, that see daily moving when a camera has been used. They’re a 32gb SD in a DSLR and a 16gb microSD in a Hero3. The micro is newish but is has been in and out of the camera a few dozen times now. The SD has been in and out of that camera a few hundred times.

I suppose it varies per brand and model how reliable they are. And how well they get treated on the move.

When I’m traveling they each get pulled from their camera, uploaded into a wolverine, uploaded into a tablet, then back into the camera and cleared daily on my routine.
(the hdmi out of the tablet can often find a connection on hotel tvs, and we can browse at the end of the day through unedited heaps of pictures and uncut snorkeling movies – “Hey, there goes that conch!” – while a nice tropical drinkie sinks in).

The microSD type seems inherently fragile, there’s just so little to them, like handling part of a potato chip as big as the fingernail on your pinkie.
It would not be hard to overpush a microSD if it’s not going into the socket with the correct side up. Or torque it when taking it in or out enough to break connections.
