Review on SanDisk 128GB (Two Pack) Extreme Pro Memory Card (SDSDXXY-128G-GN4IN) SDXC 4K V30 UHS-I Class 10 with Everything But Stromboli (TM) Combo Reader: High Performance Storage Solution by Jason Regalado

I almost always use SanDisk Extreme Pro memory cards and none of them have let me down. I photograph over 100 weddings a year, these cards are always very fast and have never given me an error code. I had 2 friends who gave me other cards claiming to be professional cards (other brands) and they both ended up giving me error codes. I'm lucky because my cameras have 2 memory card slots and I used Sandisk as a backup so I didn't lose any photos. I will not use any other brand and will stick with professional cards!
