They were discontinued for a while, but that seems to have changed. Perhaps SanDisk re-negotiated the licensing. As of yet there are no 8GB Extreme IV cards rated at 45MB/s. It appears that SanDisk intends to reserve the Ducati line for 4GB and 8Gb cards at the 45 MB/s rate and then continue the Extreme IV line at 45MB/s for 16GB cards.I was wondering too. Ive heard that the Ducati's were being discontinued and that the new Etreme IV's had the same read & write speed (45mbs ) as the Ducati had.
The old Extreme IV were only 40MB/s. This new line is 45MB/s. These cards are the most expensive ones yet released by SanDisk. No one has tested or reviewed them.
Anyone care to try a few at $400 per card?
Are you serious about the Transcend being faster than the new Extreme IV? I am using the black 300X Transcend cards in slot 2 for overflow and the Ducati cards in slot 1. This seems like the perfect match. I guess that I should keep this configuration until the 16GB cards become compelling enough to upgrade.It is available at around $250 retail here.
The Trenscend 300X and Adata 350X 16G are both faster than it for read speed.
(...) The difference is small, maybe around 1 to 2 frames in continuous RAW shooting.
