No difference just capacity. I think SD max capacity is 1GB!

Hm, well the highest I've seen for an SD card is 4GB, and 32GB for SDHC. I don't expect I'd need that much space. If that's the only difference, that's fine.

I think the only difference between the two is that the SDHC cards hold a lot more. You can get a lot with SD, anyway! 4GB at the most.

SD cards *typically* hits 2GB. SDHC is artificially limited to 32GB. That said, if you're going for something like 2GB I would get an SD card for wider compatibility. I don't quite understand the logic for 2GB SDHC cards. They may perform a bit better, but that's about it.

When browsing around for an SD memory card(2GB), I noticed three varying brands - SanDisk, Kingston, and Transcend. Kingston seems to be the most "expensive" wherever I go, and Transcend is dirt cheap. What exactly am I sacrificing in terms of quality if I were to go with the Transcend brand name? I thought each did the same exact job.

i got a small usb adapter with my sandisk sdhc card and a nice little case. using this the card will work in any computer with a usb port.

Most of the times the difference you'll find is in read and (especially) write speeds.

I have this http://www.amazon.com/SanDisk-SDSDH-2048-9...8656&sr=8-6 and the write speeds are pretty good :)

SD cards are formatted in FAT and are compatible with all devices that take SD. They are therefore limited in capacity.

SDHC cards are formatted in FAT32, thus higher capacity is allowed, the downside is only newer devices are compatible.

My Canon A540 is SD only, whereas my Creative ZEN is SDHC. Trouble is my card reader only does the SD dance so to get stuff on my ZEN I have to connect it to the PC via USB instead of the reader.

Could you reformat SDHC, theoretically, into etx3 or ntfs? (shame there's no benefit in physical size...)

Of course you can if you get an 8GB+ chip

Sigh, why do there have to be so many Sdx standards?!

No, memory addressing methods are different that allows SDHC's capacity to increase, but even if you have the same SD vs SDHC card of the same capacity it would be sector addressing vs byte addressing. :)

I believe he is right, the file format is not the only difference betweenSD and SDHC, besides you can reformat it
