Which SDHC cards work best in MxR Reader?
 

Of course must use Class 6 speed or higher card. So far, the best are SanDisk Ultra II and the Transcend cards. Just tried a Patriot card and only one third of them would format.

I haven't tried it yet but I believe ATP ProMax cards might actually be the best at the moment. I think MxM is recommending them.

These are what I've now started to buy (having real problems getting them in the UK at the moment). But they are far quicker than my newer Transcends.

But we do need to get more people testing them. Me stress testing just 2 cards isn't enough frankly.
