It’s tough to get excited every time Compact Flash manufacturer’s increase the speed of their cards. Most is just marketing hype to generate sales. However, if you have been following the discussion on my Facebook Wall, this is something real!
It all started with a YouTube video by bodnara2009 called Transcend UDMA CF Memory Test. It shows a test using the Canon 7D in high-speed continuous shooting mode using several compact flash cards (100x generic, Transcend 300x 8GB card, Transcend 400x 8GB card and Transcend 600x 8GB card). To my surprise, the Canon 7D with the Transcend 600x compact flash card just keeps shooting continuously for over 430 photos (Large JPG format) before maxing the cameras buffer. Even then, the 7D’s red light stays lite for only a few seconds before the buffer is cleared and the 7D is ready to start again. Pretty amazing!
Both the Transcend 600x Compact Flash Cards and the Sandisk Extreme Pro Compact Flash Cards are rated with read/write speeds of 90MB/s. That is double the speed rating of the Sansdisk Extreme IVs which I bought last year with the Canon 7D. But, what is even more amazing is the price. While the Sandisk Extreme Pro 16GB Compact Flash Card is currently around $190 online, the Transcend 600x 16GB card around $80 at B&H Photo. Now that’s amazing!
