• 133X write speed (21.5 MB per second)
• low power consumption

Transcend's 133X CF card targets serious users who demand superior performance and reliability from their memory cards, including professional photographers, reporters and photography enthusiasts. To ensure ultimate compatibility and speed, it operates in both dual-channel transfer and the Ultra DMA mode 4 standard.

This item works well in my Olympus 7070. With the large memory capacity, it allows me to take underwater movies with less energy consumption than my microdrives, so I do not need to replace the battery as often during multiple dives. It connected easily to my camera's processor.

So it's not the fastest card, but for the price this was a nice memory card.
By this time you can get better deals, but this card has served me well and has been very reliable. Nothings worse than finding corrupt data from a memory card, never happened with this card.

I use this card with my Sony A300K. This card is not the fastest card transfering pictures from the camera to the PC, but the write performance is good enough to get the camera's top 3 fps in continuous mode, which is exactly what I wanted. In summary, you won't need a more expensive card (i.e. the Extreme series from Sandisk) if you're more concern about been able to shoot fast than to read fast.

I bought this card nearly a year ago, and it worked fine for awhile. This summer I was on vacation in Okinawa, Japan, and I got an error while trying to view a picture I had just taken. Then about 2 months later I was using it to take photos at an event, an anniversay celebration, and after taking 6 pictures that day it began giving me errors. I stopped using it and tried to recover the pictures later at home, I was only able to get 2 out of 6 pictures off the card. So I went and bought a much more expensive SanDisk Extreme III card.

I can't recommend this card.

I was quite pleased to find such a speedy card at such a reasonable price. Instantaneous writing. Highly recommended.
