Fast CF card 28 Jan 2010
By M&M
Product Packaging:Traditional|Size Name:32GB
I purchased this card for my canon 5D mark ii, it has great speed and works a charm.

The most problems users have while filming with this camera is when they try to take a picture in film mode and the memory card stops filming where as this has no such problem due to the speed it has and does not slow down the camera at all.

I have transferred files between a firewire reader and my mac with extremely stable and fast speeds.

As to the card not failing i can only say i have been using sandisk sd cards for about 5 years now and have never had any fail.

Excellent card and terrific value from this seller. Card needed by high end DSLRs particularly the new generation that have video capability. Not necessary for lower end DSLRs with a slow frames per second capability unless the price of the Extreme III and IV cards is similar. SanDisk 8GB Extreme CF Compact Flash Cards 60MBS - Retail Pack

I bought this card to use with my sony a700.Amazon delivery as excellent as ever - arrived next morning!
I always shoot in RAW & this card can hold over 800 images at maximum quality. Since using this card I've never had any issues with buffer or card write time delays. For the price per Gigabyte ratio I think this card is unbeatable. A top product from a top brand at a great price - you won't be disappointed if you buy this card.
