Interesting discussion you have going on about CF cards. In 10+ years of me using them I have not had single one of them go bad on me. Many years ago I also purchased a bunch of used CF cards from photography forum members and all are still working. I've used Sandisk, Lexar, Transcend, Adata.

On the other hand I had several micro SD / SDHC cards go bad on me. They were brand name and they still went bad. I trust CF cards over other types.
