Can you explain SDHC memory cards to me?
There’s class 1, Class 2, and Class 6 that I’ve seen on one search. What is the difference between all these classes? Are there classes 3 through 5? Why are the earlier classes still sold?
What about microSDHC cards? Are they usable in cameras if you have the larger sleeve to put them in? Or are they only for slots that take that size card, like in cell phones?
If you get a larger microSDHC for your phone so it can have more memory, is there anything essential on the old chip that must be copied over, or do the chips only contain content?

The phones – it depends on the phone. If you have an Android, and store app info on there, you’ll probably want to copy it over onto the new card, otherwise you’ll have to start all over for a lot of apps. But if it’s a phone where you just store pictures and music and ringtones and videos and documents, then you don’t have to copy (although I find it to be much easier).
You have to use the proper size – you can’t use a microSD in a miniSD or regular SD slot.
I don’t own a cell phone or know anything about cell phones using SD cards, but, here goes.
The class is the speed, essentially. Class 6 will always be faster than Class 2, but sometimes two class 6’s from different companies will be different speeds. If transfer rate is a problem, like with a camera that takes photos a mile-a-minute, then you want the highest class possible.
SD+HC means more space, the size. SD without the HC is going to hold fewer items, always. SDHC goes up to 32gigabytes I think.
a microSDHC card is only going to fit a slot that wants a microSDHC card. You can buy an SD card that works simply as an adapter. I have an SDHC card that you can plug a microSDHC card into, to make it work in normal SDHC slots.
Hope that helps!
