Summary: Own three SimpleTech 256 and a SimpleTech 512 CF cards
Comment: I've taken over 24,000 pixs with these on a Nikon CoolPix 5000 and only once did the 512 give me a fright. But in the end, the pixs were there. It happened during file transfer from the card to a PowerMac laptop. It could've been my fault; a little careless last weekend.

Summary: Excellent
Comment: I have used this card for about 6 months and never had any problems. I used it in a Canon G5 camera.

Summary: Incompatible with Muvo2
Comment: I purchased this card and the Sandisk 512 CF. Simpletech wouldn't format in the Muvo2. The Sandisk worked like a charm. Previous experience had this card fail in a week. I should have known better. I have never had a problem with Sandisk, but have been bitten twice with SimpleTech.

Summary: Reliable, and an excellent value . . .
Comment: I use this card in a Canon 10D digital SLR camera, and have found it a very reliable performer. There have been no major problems either writing any kind of data, or extracting the files later. The larger capacity is great for digital SLR camera users. For the Canon 10D, a 6 mega pixel camera, maximum JPEG file size at the highest quality setting averages about 2.5MB, and typically about 190 images can be saved to the card. Using the card in a lower resolution digital point and shoot camera, capacity would of course be many times greater.

Speed of writing on SimpleTech cards is respectable; price is right though.

As more files are written and the card gets closer to capacity, data transfer speed seems to slow down a bit. Still the card performs reasonably well even when taking a series of images in rapid succession, say four or five in two second interval. With a digital point and shoot camera, transfer speed should not be an issue.
Competitively priced... Economical and reliable, SimpleTech's 512 card is a great value.
