Just a heads up to peeps looking at cheap 64gb cards any make or model, be warned if they are cheap that means they are second rate designs mainly made in crappy country's etc.. like Taiwan which means it will go wrong asap, especially with high end cards like the 64gb's and above. I have had 4 x 64gb's go back, 1 x Transcend and 3 x San-disc Mobile Ultra, none tested out perfect with many errors with h2testw and all went faulty within 3 weeks and had to go back! If you are looking to purchase a reliable 64gb card I suggest buying one from your local PC World etc.. don't buy cheap cause it will go faulty! and do not buy from Mymemory.co.uk or Moby Memory they both sell second rate Taiwan cheap memory tat. and don't say I did not warn you when you order and have to send it back time after time when it locks up or goes wrong. I suggest go for a 64gb PNY model, Elite make, they seem to be very good and stable with roms a bit expensive but worth it mine checked out 100% with h2testw after about a 3 hr. full test from PC World.
