I get a hot card warning on the Nikon Z8.

When recording video, the camera or memory card may get hot and a high-temperature warning or hot card warning might pop up. Let the camera cool and the warnings clear before handling the camera, battery, or memory cards.

What is the difference between CFexpress and CFast 2.0?

CFast 2.0 was released in 2012 and supports SATA-III interface with speeds up to 600MB/s. CFexpress was released in 2017 and leverages NVMe PCIe interface. Each CFexpress card has 1 to 4 lanes, which means they can transfer data at 1,000 MB/s to 4,000 MB/s.

What is the difference between CFexpress Type A and Type B?

CFexpress Type A and CFexpress Type B memory cards are both PCIe-based, although their physical dimensions and transfer speeds differ. CFexpress Type B measures 29.8mm(Width)*38.5mm(Height)*3.8mm(Thickness), whereas CFexpress Type A measures 20mm(Width) x 28mm(Height) x 2.8mm(Thickness).

Type A cards can theoretically transfer 1,000MB/s, while Type B cards can theoretically transfer 2,000MB/s.

What is the difference between CFexpress Type A, Type B and Type C?

These types of memory cards have different numbers of data lanes. The more lanes, the faster the transfer speed.

Type A cards can theoretically transfer 1,000MB/s, Type B cards can theoretically transfer 2,000MB/s, and Type C cards can potentially achieve 4,000MB/s.

Are CFexpress Type B cards the same as XQD cards?

While CFexpress Type B and XQD cards have the same physical dimensions and pin layout, they use different protocols and run at different theoretical speeds. XQD cards max out at 1,000 MB/s, while CFexpress Type B cards max out at 2,000 MB/s.

Can I use my CFexpress Type B card in an XQD slot?

For cameras with XQD slots, a firmware upgrade is required to enable CFexpress compatibility. Please check your host device’s compatibility with your camera manufacturer.

Do you also offer a CFexpress memory card reader?

Yes, we offer our single-slot, ultra-fast 20 Gbps CFexpress Type B reader for achieving 2,000 MB/s transfer speeds.

Which cameras use CFexpress Type B cards?

Some current cameras with CFexpress Type B card slots include:

Nikon Z6/Z7
Nikon Z6 II/Z7 II
Nikon Z8
Nikon Z9
Nikon D6
Nikon D850
