Review on KOMPUTERBAY 64GB Pro CF Card - 1000X Speed, 150MB/s, UDMA 7, RAW 64 GB by Roy Reeves

Don't believe what other haters might say. This is the cheapest card and can record videos in RAW format. I've only used it on the 5D MK3 and can 100% confirm it. Would buy again. Shooting in 1080p gives about 12 minutes to fill the card. I also have a 32GB card that only lasts 6 minutes and I'd recommend getting the 64GB rather than the 32GB if you're just trying water because you want more time to record. A tip for RAW recording enthusiasts: format your 1000x cards to ExFat, otherwise any files larger than 4GB will become corrupt and personally annoying. That means you can't format on the camera, but that's not the card's fault. Get this card.
