Sorry... I've been a photographer for a long time. I purchase the cheapest SD/compact flash cards I can find..(Not *bay though).
I've bought numerous off brands, such as ridata, adata, patriot, dane-elec, wintec, transcend, amazon basics, etc.
You don't need a name brand ! There are standards all the memory cards have to meet and most come with at least a 1yr warranty.
With all that said.. I've NEVER had a sd/compact flash card failure and I've bought 50+ cards. Doesn't mean things don't happen, but cards are very reliable.
