Choosing an SD card

Somewhere I read that an SD card class 4 was required by the Raspberry Pi. Would an SDHC Class 6 or higher class card work? I am partial to SanDisk cards which I use with a high quality DSLR camera.

Thanks in advance

Marv,
preliminary SD card info is at:
http://elinux.org/RPi_VerifiedPeripherals#SD_cards

In some cases, a higher-end SD card may work, but not
at full speed, because the RPi apparently can't shift down
to the 1.8V interface.

In some cases a higher-end SD card may not actually be faster,
depending on whether you do I/O in small chunks or large contiguous blocks.

Also, you may get better performance from a hard drive
connected to a USB port. Once the RPi is booted from the
SD card, you can mount your filesystem from a USB drive.

And of course be sure to get your SD card from a reputable
source, because there are apparently lots of fake cards for sale.
