Q: 9. Can I use my current Sony XQD- card reader MRW-E80-with this CFexpress card?

A: I contacted Sony USA concerning your inquiry. According to Sony, the MRW-E80 XQD Card Reader has only been tested with XQD cards. As the card reader has been discontinued, they cannot confirm if CFexpress Type B cards would be compatible with this reader, and they have no firmware updates designed for the card reader for updated compatibility. The best I can state is if you already own the MRW-E80 card reader and you have a CFexpress Type B card, you may test the card in the card reader to see if it will work for your usage needs. However, Sony recommends using the MRW-G1 CFexpress Type B/XQD Memory Card Reader, B&H # SOMRWG1T1, which is their newer updated card reader designed for use with both XQD memory cards and CFexpress Type B memory cards.

Q: 10. Will this card sustain writing fast enough to record 8k video with the Canon R5?
