PERGEAR Unveils a 2TB CFexpress Type-B Card

The PERGEAR CFexpress Type-B 2TB Memory Card is a new low-cost alternative to more expensive cards, however, it still boasts impressive performance. This is the latest addition to a family that already includes 64, 128, 256, 512, and 1TB-sized media. The entry model is the one that features the highest read and write speeds.

CFexpress cards have only been around for a few years and higher capacity versions can be expensive. Their theoretical read and write speeds far exceed most cameras that are using them, however, sustained write speeds are what you need to really pay attention to. With certain cameras, if you use a card that has doesn’t have a high enough sustained write speed you are going to run into big problems.

According to PERGEAR, the card has a maximum read and write speed of 1600MB/s and 1500MB/s respectively. However, the guaranteed minimum sustained write speed is 800MB/s. That is enough to record 8K RAW at 30fps on the Canon R5, for example.

For reference, the 2TB version of the industry-leading Angelbird AV PRO MK2 has a maximum write speed of 1550MB/s, but it can sustain a higher write speed throughout the whole capacity of the card (1300MB/s).

According to PERGEAR the 2TB card is compatible with the following cameras:

  • Nikon Z6
  • Nikon Z6II
  • Nikon Z7
  • Nikon Z7II
  • Nikon Z9
  • Nikon D500
  • Canon C500 Mark II
  • Canon C300 Mark III
  • Canon 1DX Mark III
  • Canon EOS R5
  • Panasonic S1
  • Panasonic S1R

In cameras such as the Nikon Z6 and Z7 that only feature a single lane PCIe 2.0 interface, the camera can only read and write to CFexpress cards at throttled down speeds that are similar to what you would already get with an XQD card. As these cameras don’t even use the full write speed capabilities of XQD cards, CFexpress won’t offer any increased in-camera performance.

This new CFexpress Type-B card is now available for purchase from the manufacturer’s website for $599. That’s approximately 30% less than the Angelbird 2TB AV Pro MK2. You can also buy the PERGEAR 2TB CFexpress Type-B Memory Card with Dual Slots USB 3.1 Gen 2 Type-C Card Reader for $619.
