    Beginners guide to buying an SD card

    Here is a little guide on how to buy an SD card and i found it quite helpfull. If you don't like reading, the TLDR version is : don't ever buy a cheap SD card because in the end it may cost you more.

      To me this is another example (on the linked site) of someone making a statement without any evidence. There are always people who insist only the most expensive thing is worth getting. If someone can show me statistical evidence that cheap SD cards are more likely to fail than expensive ones, I might listen. Yes, get a card with the speed and capacity you need, but I suspect most of them are made in a very few factories and just badged (and priced) according to the brand name. I've never had a card problem, apart from the one which I accidentally forced into the wrong part of a card reader and ripped off one of the contacts, my fault, not the card.

          Lots of info on the web and got to say some of it is rubbish.

          Interestingly just been testing the CF cards I have to see how they compare.

          Used a prog, H2testW, and a Kingston USB3 reader, the results aren't absolutes and they will vary with the equipment used for testing. Given the different interfaces in cameras there will be differences there too.

          Anyway these were the results:
          SanDisc Extreme Pro 32GB UDMA7

          Writing speed: 103 MByte/s
          Reading speed: 107 MByte/s


          Lexar Pro 800x 32GB UDMA7

          Writing speed: 38.1 MByte/s
          Reading speed: 107 MByte/s

          Not surprised at the difference as the Lexar is rated slower. In use in my 5D3 can't say I've really noticed a difference, maybe I'm not shooting long enough to fill the buffer where the slower write speed of the Lexar would be an issue. From all I've been reading recently (looking to buy some more CF) the Lexar 1066x should perform the same as this SanDisk.

            All my cameras have PNK cards in, happy with them too.
