Memory Cards

San Disk and PNY. 32 and 16GB. I have no pros or cons. I've not had one fail me . . . yet.

Rest assured one will eventually fail.

This won't specifically answer your question, and is fairly technical, but there's a lot of useful information in the article that many of us could benefit from, as regards using memory cards reliably. It's a recent interview with the CEO of a major data recovery company:

Some of the information I was aware of, and some I figured out the hard way(!):

Generally I'd use well known brands (Sandisk Lexar, etc.), and buy them for reputable sources. There are plenty fake ones about, from not-so--reputable sources, so take care.

Best wishes.

Thanks for the links Peninsularlight. Now I know why have have yet to experience a card failure - I keep buying new cards and use the full ones as backups which I will reformat once the images are saved on other media.

Thanks all :)
