Delkin's latest SD cards actually lose features to enhance their ruggedness

Delkin has updated its Black Rugged line of SD cards, but unusually the differences aren't found in the usual increase in read/write speeds. Instead, Delkin has subtly redesigned the plastic SD card casing - a form factor we now take for granted - by removing the write-protect switch on the edge, as well as the thin plastic ribs that run between the card's electrical contacts.

The two changes should mean that you should avoid shards of plastic falling off the card and fouling your camera's memory card slot, or that of your card reader.
