What's the practical difference you feel while using SD and SDHC cards?

Question

I bought a Canon SD790 and have a SanDisk 2GB SD card. I have heard people say and read about it saying SDHC will give you higher capacity. But practically speaking what difference would I feel while operating a camera?

Answer 1

You would feel no different ...  The SD cards maximum capacity is 2GB while SDHC (high capacity) start at 4GB and go up.  They are by design the same physical size.

The only thing you may feel is relief that you will not fill the card before you are finished shooting.

As mentioned, most of us use card readers to copy our images over to the computer ... as capacities increase, it takes longer for the image files to move from the card to the computer.   I have a number of 16 GB cards, so using a card reader is the only practical way to do it.  I recently bought an ExpressCard/54 which can transfer images at speeds of up to 2.8 GB/sec ... which is nearly six times faster than a USB 2.0 reader, seven times faster than firewire.

Answer 2

None. It just puts more room on the card. Cards have gone from 8 megs to a bunch of gigs over a very short period of time. There are cards now that most card readers can't even read if they are over 2 gigs. Unless you are using RAW mode and planning on doing large poster work it is just hype due the cards now have greater room. For video work that is a different story, but for photography, so??? I covered this years international air show in Dayton (again, have been for several years) and took over 300 pics on a 1gig card and hardly used up half of it.
