Product description

The Element Pro CFexpress 4.0 Type B card reads at up to 3,500 MB/s and writes at up to 1 400 MB/s with a sustained 450 MB/s — for 8K and 12K recording at up to 120 fps without dropped frames. It is compatible with the Canon EOS R5, R5 Mark II, R3 and C500, Nikon Z6, Z8 and Z9, Atomos Ninja TX and Blackmagic PYXIS 12K and URSA Cine 12K. 256 GB capacity, 150 TB endurance, 3-year warranty.

CFexpress 4.0 Type B with up to 3,500 MB/s

PCIe 4.0 doubles the bandwidth of Type B cards: 3,500 MB/s read, up to 1 400 MB/s write and just 1.25 W at a sustained 400 MB/s write. Up to 2 TB capacity, 3-year warranty.

PCIe 4.03,500 / 1 400 MB/s256 GB150 TB TBW3-YEAR WARRANTY

For Canon, Nikon and Blackmagic

The card is compatible with the Canon EOS R5, R5 Mark II, R5 C, R3 and C500, Nikon Z6 II, Z8 and Z9, Atomos Ninja TX recorders and the Blackmagic PYXIS 12K and URSA Cine 12K cameras — anywhere with a CFexpress Type B slot. CFexpress 4.0 is backward compatible: in an older slot it runs at that slot’s speed, in a new one it uses PCIe 4.0 to the full.

8K and 12K at up to 120 fps

A sustained 450 MB/s write on the 256 GB version and a sustained 3 300 MB/s read handle RAW recording in the highest profiles. Adaptive Thermal Control™ stops the card throttling on long shoots, SuperCruise™ keeps the write speed stable and RAID ECC can rebuild even severely corrupted data.

Low power, longer shoots

At a sustained 400 MB/s write the card draws around 1.25 W — less than typical CFexpress 2.0 cards — and Smartstream™ balances performance and power draw so the body lasts longer on one battery. 3,500 MB/s read through a USB4 reader moves a full card to the edit suite in minutes.

Industrial foundation

3D TLC memory, 150 TB write endurance, an MTBF of 2,000,000 hours, operation from −12 to 72 °C and storage from −40 to 85 °C — figures from the industrial storage Exascend builds on.

PCIe 4.0, NVMe 1.4

Twice the bandwidth of CFexpress 2.0 — up to 4 GB/s on Type B cards.

Data Retention Plus™

Stored data is refreshed continuously before the natural degradation of flash memory can put it at risk — even under extreme workloads.

Afterburner™

Full performance in burst shooting and fast action; the card does not choke even on long RAW bursts.

256 GB to 2 TB

The Element Pro Type B series comes in four capacities; this is the 256 GB version with 150 TB endurance and a sustained 450 MB/s write.
