microSD or microSDHC?
 

Next week I will be picking up my N900. I want to buy a microSD memorycard for it, but I'm confused.

In the (digital) manual from the N900 I read that I should use microSD cards (also on the Nokia N900 productpage). But when I visit the shop and look at the accesoires there is a microSDHC card listed: "Nokia 16 GB microSD-kaart (MU-44)".

I assume that only microSD's are supported?

HC stands for High Capacity

Re: microSD or microSDHC?
 

I know. But I'm not sure that microSDHC is backwards compatible with microSD.

Re: microSD or microSDHC?
 

It definitely supports microSDHC: I've just looked at the 8 gig card I regularly use witn my n900...

Re: microSD or microSDHC?
 

Yes, of course they're fully backwards compatible. It'd be rather silly if it wasn't.

Just like USB 2.0 is backwards compatible with USB 1, etc.

Thanks for the info TomJ, that leaves no room for argument.
Too bad this info isn't put in the manual or on the websites...


Except that devices NOT designed for microSDHC cards can't access those (as far as I know, please correct me if I'm wrong). Of course devices designed for microSDHC can access the "older" microSD.

Re: microSD or microSDHC?
 

That's correct. microSD had a maximum size of 2G (IIRC), and microSDHC has a maximum of 32G. You're unlikely to run across any modern equipment (except for, in my experience, all-in-one card readers) which don't support SDHC.

The 8 GB microSDHC card in my N900 that works fine.

A 16GB SDHD card works fine in my N800 after updating the firmware to Diablo even though the original firmware only supported SD cards up to 2GB.

This is largely a software issue caused by the older cards using a FAT16 filesystem to support up to 2GB. The newer HD cards use FAT32, and the XD cards will use yet another filesystem to go beyond 32GB.

Btw, is A-Data a good memory card manufacturer?

A-Data 8gb class 6 microsd card costs around 26 $ in ebay, and they advertise life-time warranty in A-Data's web site.

Well, I think my nest device will be one supporting SDXC. I have a camera supporting sdxc and I want to use a microSDXC in it and on my next smartphone.
