  1. Les, In the second paragraph you state the Canon EOS R5 can capture photos at 20 per minute. This should actually state 20 per second. From Canon’s website: “EOS R5 camera features a selectable electronic (silent) shutter mode, and can capture images at up to 20 fps”.

  2. Awesome. Thank you for the review! Looks like I know what to get between the three CFx-B card; ProGrade Digital Cobalt 650GB, Delkin Devices Black 512GB and Wise advanced Pro 650GB.
    Delkin devices Black 512GB looks like a clear winner in terms of performance and operating temperature follow by ProGrade’s and then Wise’s.

  3. “The 640GB sample is most likely a 1TB CFExpress card overprovisioned.”
    I would challenge that assumption, as it makes more sense that the 640GB card is actually a 2TB card with overprovisioning. Multiply 640GB (or 660GB for some other manufacturers) by three and you get near enough to 2TB. Additionally, notice how 2TB and 640GB are the highest capacity cards in each product series, meaning that they probably have the same nand chip quantity and density.
