Q: Why do I need a VPG400-certified CFexpress Type B card?

Attention Sony camera users: To ensure optimal performance, it’s crucial to use VPG400-certified CFexpress Type B cards. As of March 2024, Sony has confirmed that none of their cameras are compatible with non-VPG CFexpress Type B memory cards. These VPG400-certified cards guarantee consistent write speeds of at least 400 MB/s, significantly reducing the risk of frame drops and freezes. This reliability makes them perfect for demanding tasks like high-resolution burst photography and shooting high-bitrate videos.

Q: What is the difference between CFexpress 2.0 and 4.0 memory cards?

CFexpress 4.0 cards are engineered to operate on advanced PCIe Gen 4 interface, effectively doubling the bandwidth compared to the previous CFexpress 2.0 standards. This allows them to set a new benchmark with maximum speeds reaching 4GB/s for Type B and 2GB/s for Type A cards.

Q: Is CFexpress 4.0 backward compatible with CFexpress 2.0?

Yes, CFexpress 4.0 cards maintain full backward compatibility with CFexpress 2.0.

Q: 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).

Q: Do you also offer a CFexpress 4.0 memory card reader?

Currently, we offer a single-slot 20 Gbps CFexpress Type B reader, which delivers 2,000 MB/s transfer speeds. We are also launching a 40 Gbps CFexpress 4.0 Type B reader very soon.

Q: 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, Canon EOS R5, Canon C500 Mark II, Canon EOS-1D X Mark III, Canon EOS R3, Panasonic Lumix S1 / S1R, Fujifilm GFX100 II, Fujifilm X-H2S / X-H2.
