The 64GB PRO from Samsung convinces me in all facets. Previously I used SanDisk SD cards, however, the non such protective routines on: Samsung promises in its 10 year guarantee water resistance in the salt water up to 24 hours, cold and heat resistance, magnetic and X-ray protection and 1.6 tons load capacity (!). Surely I'm not all these features make fullest, but salt water and heat / cold come before me, because I'm on the road a lot as animal and travel photographer in Northern Europe. Curly made me especially the unbeatable price for this great memory of this brand product as well as the impressive read / write rates. All my cameras (EOS 5D, 60D, 40D) have clearly gained in performance. Ingenious Card! - Will I be in the future prefer SanDisc.
