Review on 💾 KOMPUTERBAY 128GB Professional Compact Flash Card CF 1050X | Enhanced Speed UDMA 7 | RAW 128 GB | Read 160MB/S, Write 100MB/S by Tony Hanson

I followed all the instructions: I used a UDMA 7 compliant USB 3.0 card reader (Lexar) formatted as XFAT. The basic copies of the files did not work. Deleting the file didn't work. I repartitioned the 32GB partition and formatted it to FAT32 thinking there might be a problem with xfat. That won't work either. Exactly the same problem. I then loaded this into my 5d Mark II and started shooting some test shots and short videos. There were no recording errors. But during video playback it just freezes. And the camera returned an error saying the file is unreadable. I put the card in the card reader and tried to eject it, my computer said the card was corrupt and needed to be reformatted. There was not a single case where the card worked! This is a completely useless card. Don't waste your time and money. The good news is that Revain got my money back. I will use this for a more durable and reliable map.
