PERGEAR 2TB CFexpress Type-B Memory Card

PERGEAR 2TB CFexpress Type-B Memory 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.

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.

Fast Speeds

The PERGEAR 2TB CFexpress card is claimed to provide max. write speeds of up to 1500 MB/s and read speeds of 1600 MB/s. The max sustained write speed is claimed to be 800 MB/s which is impressive.

Record 8K RAW from the Canon R5

CFexpress uses a dual-lane PCIe 3.0 interface that enables it to meet the high read and write speeds that are quoted by card manufacturers.

Cameras with dual-lane PCIe 3.0 interfaces, can certainly take advantage of the high write speeds CFexpress offers. From what I understand, the Canon C500 Mark II and R5 both use a dual-lane PCIe 3.0 interface.

In theory, the speeds offered by the PERGEAR CFexpress Type-B 2TB Memory Card certainly should make it capable of recording 8K RAW from the Canon R5 without breaking a sweat.

Above you can see the card requirement speeds listed by Canon for recording 8K on the R5.

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.

Fast Media Offload

What you clearly need to remember, and this goes for any type of media, is that transfer speeds will vary depending on both the read and write speeds of your card, your card reader, and what type of hard drive you are transferring to.

If you are using a CFexpress card and transferring to an HDD drive, you won’t be getting fast transfer speeds. If you are transferring to a very fast SSD then you will see lightning-fast offload speeds.

As you can see, the PERGEAR 2TBGB card is the cheapest 2TB option available. Now, you may be thinking that maybe the card won’t be as reliable as other options because it is a lot cheaper, however, PERGEAR offers a 5-year warranty where they will replace your card if it fails.

The card has a listed working temperature of 0° C ~ 70° C and a
storage temperature of -25° C ~ 85° C. I am a bit concerned that the lowest operating temperature is only listed as 0° C which could make it unsuitable for use in some countries in winter. However, the inside of most cameras gets fairly warm quite quickly once they are turned on.
