Fast, reliable, and high-capacity. With consistent performance and vast storage capacity, Transcend’s 133x CF cards are the perfect match for enthusiast and prosumer level DSLR cameras and camcorders.
Excellent PerformanceSupporting Ultra DMA mode 0-4 (Default setting: Ultra DMA 4), this Transcend 133x CF card with dual-channel support features premium data transfer rate of 15-40MB/s (max), delivering outstanding, reliable shot-to-shot performance and fast transfer to computer.
Rich FeaturesBuilt-in hardware ECC technology detects and corrects error for data integrity. Low power consumption extends battery runtime so you can take more shots on a single charge.
Pros: HUGE data capacity - 32 gig means I can shoot RAW format all day at the track without dumping to a laptop or changing cards Great price for the storage!
Cons: Each 32gig dump on my laptop brings me that much closer to filling the hdd. :) (Not really a problem!)
Overall Review: I've been using the Transcend disks for a few years now, and have never had an issue. Bonus for Canon 40D users - our cameras are not capable of the faster bus speeds, so 133 transfer rate is as fast as you need to go. Don't waste your money on high speed cards!
