Summary: Terrible customer support
Comment: About 6 months after I started using my SanDisk card in my Canon camera, I started to get "memory error" problems. I reformatted the card in the camera and that got things working for a few more months. Now, reformatting using the camera doesn't work.
I called SanDisk customer support and they told me I need to reformat using a card reader. Then they told me I am supposed to reformat the card twice a month using a card readder. When I told them I don't have one, they told me to go buy one, or go visit a local Staples or Office Depot and try to use theirs! Are these guys kidding??? Reformat twice a month? Walk into a store and ask the sales guy if I can borrow the use of a card reader???? No way!
When I insisted that SanDisk replace the card, they reluctantly agreed to do so, and even then, they said they would only replace the card this once since I failed to follow the "standard procedure" of using a card reader to reformat the card. All this over a $25 card. It would have be so much easier for them to simply offer to replace the card at the outset without all the attitude. I'm never buying SanDisk again.

Summary: Quality Card. Period.
Comment: My Canon S410 came with a tiny stock card and I soon found the need to upgrade. This is a 4 MP camera and I set it on medium size and quality and can fit about 400 pictures on one card.
(My wife however actually finds a way to fill the whole thing in a day!) It has great compatiblity, size and dependability. As it fits in the canon, into the card reader built into my PC and has never never corrupted. The only regret I have is that I spent $40 on it at a local "Costco's" and now it's $25 at amazon.

Summary: How many pictures will it store?
Comment: How many pictures will it store? It is the most commonly asked question from digital camera enthusiast but usually the question that is the most difficult to get a straight answer about. Well, considering I worked in the memory industry for over 7 years I can help clarify this perplexing question and do so unbiased as I have since changed industries.
The SanDisk SDCFB-256-A10 256MB CompactFlash Card, like most 256MB cards, will store on average 284 pictures when used with a 2 megapixel camera, 213 images when used with a 3 megapixel camera, 128 pictures when used with a 4 megapixel camera, 102 images when used with a 5 megapixel camera, and 80 pictures when used with a 6 megapixel camera. These numbers are based off the assumption that you are going to shoot your images at the highest quality JPEG setting available for the camera and understand that they are estimates and may be off by as much as 10 percent due to numerous factors including the complexity of the scene being shot and the compression algorithm used by your specific camera.
I truly hope this review was helpful to you in determining whether this card is the right capacity for your specific needs.
