I carry around three 2GB cards (one Lexar, two SanDisk Extreme III). I often take photos at motor racing events and shoot hundreds over a weekend so I need plenty of card space. I mostly buy SanDisk cards because last season SanDisk provided sponsorship for the car that my favourite driver races!

I recently had a bad experience with a couple of cards purchased from an Amazon Marketplace seller. Both cards turned out to be faulty - one of them failed during a motor race, so I would have been stuck if I hadn't had another card. Fortunately a technically minded friend managed to recover most of the photos. Far worse, although sold and packaged as SanDisk cards (with authentic-looking packaging and labels), the cards also tunred out to be fakes. SanDisk has confirmed that they are not genuine products because they don't have any numbers printed on the side of the cards. I've put in a refund claim via Amazon, but it shows that you have to be careful.
