Review on SanDisk (Five Pack) 256GB SD Extreme Pro Memory Card Works With Digital DSLR Camera 4K V30 UHS-I (SDSDXXY-256G-GN4IN) Bundle With (1) Everything But Stromboli (TM) Combo Reader by Christopher Gulledge

This is amazing and a lot cheaper than I could find elsewhere. Each SanDisk card comes with its own protective sleeve. One thing I want to share is that you cannot transfer large files of 4GB or more with SanDisk cards. However, the simple solution is to right-click the storage device in File Explorer, select Format and change the file system from the default FAT32 to NTFS.
