I admit that before starting this blog, I was absolutely clueless myself, but the differences between the 3 memory card formats is pretty simple to understand.

The Main Differences Between the 3:

Micro Secure Digital (Micro SD Cards) – These cards are only available in sizes from 8MB – 2GB. As you can see, their storage capacities are laughable now, but when released, those numbers were a big deal.

Micro Secure Digital High Capacity (MicroSDHC) – MicroSDHC cards are available in sizes 4GB, 8GB, 16GB & 32GB. A few years ago these where considered to be must-haves for mobile phones, now they are cheap options for people not looking for a lot or space or those who don’t want to spend a lot of money.

Micro Secure Digital eXtended Capacity (MicroSDXC)MicroSDXC cards are the new kids on the block and they come in sizes from 48GB – 2TB. You can only use these cards in devices that take SDXC. SDXC devices will be able to take SD & SDHC cards as they are backward compatible.
