SanDisk Extreme IV CompactFlash 8GB Memory Card
£58.99
Very Fast - But Watch Out For Fakes - I use this card for my Sony Alpha A350, and I ve never encountered speed issues because of it. No regrets.One warning I would offer is to buyers who see this card (or others like it) on Amazon Marketplace at a price that s too good to be true. Chances are, it is. I originally purchased this from an unknown seller, and found the speed to be lacking.Although the packaging and the card were rather convincing, I suspected it was a fake, so I checked with Sandisk. Sure enough, it was. I soon returned it and bought the genuine article from Amazon.If your Extreme IV seems slow, if it doesn t come shrink-wrapped, if it seems at all suspicious - call Sandisk. They can verify its genuineness by checking photos of it.
