The following information has been pulled from the ATP product page and posted here for your convenience.

The ProMax II CF 650X CompactFlash® (CF) memory card provides ultimate high-speed performance and reliability for professional photographers, with industry-leading 650x (97.5MB/s) write speed. The card provides support for high-resolution UDMA-enabled DSLR cameras, lets you store large photos and capture high-definition video without any choppiness or dropping of frames.

The ProMax II CF 650X can also dramatically increases card-to-computer transfer rates when paired with a UDMA-enabled reader. The ProMax II 650X CF card is available in 16GB capacity.

By utilizing best in industry components together with ATP tuned configurations, ProMaxII cards are specifically made for those users looking for the fastest write transfer speeds available. ProMax II CF cards take advantage of the UDMA interface reaching a read speed of up to 300X or 45MB/sec (models under 16GB). All ProMaxII cards also allow for write transfer speeds at up to 30MB/sec, maximizing the potential for DSLR cameras and HD camcorders.

ProMax II CompactFlash cards are also all built with ATP SIP technology, allowing for water, ESD, and dustproof durability. These durability features, combined with the highest performance, make them the perfect choice for professional photographers who demand the highest quality from their memory.

Test Setup:


For this review we used the speedy Addonics ADSACF-N SATA CompactFlash card reader.  This device supports UDMA enabled CompactFlash cards and is about the fastest CompactFlash card reader we could get our hands on.  Some Firewire 800 card readers are available as well and they should certainly push the limits of this card.  As previously mentioned, we also used a Nikon D300s DSLR camera that shoots in continuous mode at 7FPS with the built-in battery and up to 8FPS with the additional MB-D10 battery pack.  For this review we used the MB-D10 battery grip in order to push the limits of this card.

In Camera

For comparison in both HDTach as well as the actual camera tests, we compared the ATP ProMax II 16GB with the SanDisk Extreme Pro 600x card and an affordable Lexar 8GB 80x card.
