Silicon Power 128GB CFast2.0 CinemaPro CFX310 Memory Card, 3500X and up to 530MB/s Read, MLC, for Blackmagic URSA Mini, Canon XC10/1D X Mark II and More

I bought two of these cards and I could only get them to reach ~190MB/s write and ~390MB/s read. No where near the 330MB/s write and 530MB/s read. I'm really not too surprised considering they only cost $90 a pop. They still work well and are faster than just about any SD card for $90. They work for what I need. I just wish they would advertise a little more truthfully.

So far it’s worked perfect with my Blackmagic Pocket Cinema Camera 4K and works at all codecs so far with no problems.It can do 4K 60fps but only on lower codecs. Braw Q0 was less then 11 seconds & ProRes HQ was about 17 seconds. Braw constant bitrate 5:1 was fine & ProRes 422 was fine also.Ultimately my hope is this card doesn’t fail on a trip. I’m using this mainly as a backup to the SD card.

Idea to use this as a backup memory card. I use Bmpcc4k to capture memories. It’s very convenient and lightweight. I swayed away from using a ssd card because of all the connections etc….so I went with a more run and gun style plus memory card protection. I will say tho. (For Bmpcc4k) at 3840x2160 12:1 and 24fps can record up to about 67-72 minutes of time. So be mindful of the memory being used. I recommend 256 for main use and 128gb for backup

I use both the SP Cinema Pro and a PixelFash HyperCore for my Canon. Both preform well without a hitch, however the Cinema Pro is a tad bit faster when transferring files from the card via a reader to my editor. Price-wise the Cinema Pro is slightly cheaper, if you're trying to save a few dollars but not by much. Either of the above mentioned Cfast cards will do the job and give you the results you need.

I know this isn't the fastest read/write card, but I have been using it for weeks with BRAW 5:1, 8:1, and 12:1 and it has worked wonderfully. A must purchase if you typically use an external hard drive and want to go light on a gimbal and not have to worry about additional balancing/cabling. Well worth $75-100 bucks.

I bought this for a wedding shooting and all the footage went missing. The whole card burn out for no reason. I was very frustrating. Every other cards work well with my camera, only this brand is acting strange. Don't recommend at all.

Awesome card for my new Blackmagic Pocket 6K.6K recording is working.120FPS only works for couple of seconds. But I don't need it. Overall great card!!!

This card works great with the red Komodo , saving 50% of the money on any other coast cards . I will buy this brand only

Great for use in Blackmagic cameras!
