With respect Bob, virtually all SDHC card maufacturers do advertise the
card's speed - on the card itself. You'll see a number (usually within a
circle) which indicates that card's speed and is called "Class".
Respectively,

Class 4 is rated at 4.0 or 4.8 MBytes per second.
Class 6 is rated at 6.0 MBytes per second.

Doesn't seem to apply to the SDHC cards I have:

SanDisk - labelled class 4, and 15MB/s

DaneElec- labelled class 6, and 133X (19.95MB/s)
