What the difference between MicroSD and MicroSDHC?

Answer 1

MicroSD are normal MicroSD cards, which are equal or less than 2GB storage.

MicroSDHC are High Capacity MicroSD cards, which are equal or bigger than 2GB and less or equal than 32GB.

MicroSDXC are Extreme Capacity MicroSD cards, which are equal or bigger than 64GB.

At the moment there are none MicroSDXC cards. It's interesting to read http://www.teamcyclops.com/forum/showthread.php?t=11110 and http://phandroid.com/2009/01/08/coming-soon-2tb-memory-cards/ about MicroSDXC cards (which could have a storage of 2TB). That's awesome.

Some devices have a limitations. E.g. it's impossible to use a 8 GB microSDHC card on Sony Ericsson K750i, but it's possible to use a 2GB microSD card.

Answer 2

MicroSD cards are older than MicroSDHC cards and due to their design, can not be manufactured to hold more than 2GB of data. MicroSDHC cards can hold more than 2GB of data and are typically faster. The extra "HC" stands for "High Capacity". You can not use a MicroSDHC card in a device that has a MicroSD slot (Camera, card reader, MP3 player, etc), but you can use a MicroSD card in a device that has a MicroSDHC slot.

Answer 3

MicroSD has a capacity up to 2GB and then the rest 4GB up is MicroSDHC from it's name SDHC it's Scandisk High Capacity which mean it has a bigger memory capacity. To add up, if your device is compatible with MicroSDHC you can use both MicroSD and MicroSDHC while on the other hand device that's compatible with MicroSD takes MicroSD itself.
