The Belt of Venus
Dusk off the coast of Patagonia (A2_074532)
This isn’t really surprising, as I have no UDMA 7 cards. The only such card I’m aware of is the 128 GB SanDisk Extreme Pro (advertised as a “100 MB/s” card). Given that B&H [affiliate link] currently sells this card for US$1150, I don’t think this is an issue I have to worry about just yet.
With these updates, the 1D Mark IV’s and 5D Mark II’s card-writing speed for UDMA 7 CF cards is about 3.3 times faster than it was with earlier firmware versions. However, even with the new firmware, the cameras’ card-writing speed is about the same for both UDMA 7 and UDMA 6 CF cards.
Sounds like there was a bug in the earlier handling of UDMA 7 cards…
