SanDisk announce Extreme IV CompactFlash cards

I am quite a fan of SanDisk compact flash products, I use three Ultra II cards (and gave away one of the same as the Picture A Day Challenge Prize). Up to now I haven’t purchased the higher speed and capacity Extreme III but now SanDisk have superseded even that with the new Extreme IV. As SanDisk are usually measured as the fastest Compact Flash cards around this should rock.

SanDisk Extreme® IV line of CompactFlash® digital film cards for professional photographers. The line is targeted at photographers who require the highest possible performance and the largest capacities for their medium format and high-end digital single lens reflex (SLR) cameras. The SanDisk Extreme IV cards are available in capacities of up to 8-gigabytes (GB)1 and deliver minimum read and write speeds of 40 megabytes per second (MB/sec.)2 making these the fastest flash memory cards in the world. This exceptionally fast card speed is critical when shooting large numbers of high-resolution images.

When do you need the speed? Sports events and shooting scenarios where targets will be fast moving, where you will be using continuous rapid fire approach benefits by clearing the buffer faster with swifter writes. Also if you shoot RAW where you have higher file sizes the transfer to your computer is usually speeded up. For normal shooting the older cards would suffice although I do find there is a reliability improvement by buying the more expensive disks, I have only had failures so far on cheaper products.
