Question 1

What cameras are compatible with a CFexpress Type B card?

Accepted Answer

CFexpress Type B slots are found in a range of professional and enthusiast bodies, including the Nikon Z9 and Canon EOS R5. Always check your camera's manual to confirm the exact card format it accepts — some bodies have dual slots that accept both CFexpress Type B and XQD. Note that not all Sony or Panasonic bodies use Type B; several use CFexpress Type A or standard SD cards instead, so verifying your specific model is essential before buying.

Question 2

Is 300GB enough storage for professional video work?

Accepted Answer

300GB covers a solid day of shooting for most workflows. High-bitrate formats like 8K RAW are storage-hungry, so how long 300GB lasts depends heavily on your codec, resolution, and frame rate settings. For 4K or compressed formats, 300GB comfortably handles a full day's work before you need to offload. Check your camera manufacturer's documentation for the exact data rates of your chosen recording format.

Question 3

What does 1750MB/s read speed mean in practice?

Accepted Answer

1750MB/s is the maximum read speed, which determines how fast you can transfer footage from the card to your computer or card reader. A fast read speed means offloading a full 300GB card takes only a few minutes — a real time-saver during a busy shoot day. It also supports sustained high-bitrate video recording by ensuring the camera can access data from the card quickly during playback and buffering operations.

Question 4

Is buying a used CFexpress Type B card safe?

Accepted Answer

Yes, provided the card has been properly inspected. Flash memory doesn't wear the way mechanical drives do, and a card used for typical photo/video work retains nearly all its write endurance. On Camera-tweedehands.nl, every second-hand card is individually checked and comes with a minimum 12 months warranty, so you're covered if anything comes up.

Question 5

Do I need a special card reader for CFexpress Type B?

Accepted Answer

Yes — CFexpress Type B cards require a dedicated CFexpress Type B reader or a compatible multi-format reader that explicitly lists Type B support. Standard CFast or SD readers won't work. To get the full 1750MB/s read transfer speed, make sure your reader connects via USB 3.2 Gen 2 or Thunderbolt.

Question 6

How does Renice compare to other CFexpress Type B brands?

Accepted Answer

Renice positions itself as a performance-focused alternative to the more widely marketed brands. The 1750MB/s read spec sits in the upper tier for Type B cards, making it competitive for professional use. If you're deciding between brands, focus on the rated speeds and warranty coverage — a pre-owned Renice card with verified inspection is a practical choice when budget matters.
