Descriptions

B1 Pro Series (NX-B1PRO) – Achieves the world’s fastest[1] read speed of up to 1,950 MB/s[2], write speed of up to 1,900 MB/s[2] and a minimum sustained write speed of 1,800 MB/s[2] supporting VPG400 (guaranteed minimum sustained write speed of 400 MB/s) for all capacities ranging from 165 GB to 1,330 GB: ideal for high-speed continuous shooting of RAW images as well as 8K video recording at higher bit rates without dropping frames with the latest high-performance mirrorless cameras.

The B1 Pro Series CFexpress Type B card is equipped with “Dynamic Auto Power Save,” a unique system developed by Nextorage for low-power consumption during video recording. The B1 Pro series offers up to 68 %[2] power savings compared to non-equipped pSLC CFexpress cards. This system not only saves the camera’s battery life, but also prevents thermal throttling* from triggering by reducing the temperature rise of the card. This interaction contributes to maintaining sustained write speed during high-speed writing in video recording. (*Thermal throttling: a control function that suppresses the transfer speed to prevent thermal runaway)

B1 SE Series (NX-B1SE) – Primarily for high-resolution still photography, this series comes in 128 GB and 256 GB capacities. Thanks to the world’s fastest[1] read speed of up to 1,950 MB/s[2](up to 1,100 MB/s[2] for 128 GB) write speed of up to 1,100 MB/s[2] (up to 550 MB/s[2] for 128 GB) and minimum sustained write speed of 200 MB/s[2](at least 100 MB/s[2] for 128 GB), photographers can greatly streamline their workflow from shooting, backup, editing, and sharing.

Durability

Both the B1 Pro and B1 SE series are durability tested in an environment compliant with CompactFlash Association regulations:

  • Temperature resistance: -10 ℃ to 70 ℃ / 14 ℉ to 158 ℉(Operating temperature)
  • Shock resistance (EIA-364-27A compliant)
  • X-ray resistance (ISO7816-1 compliant)
  • UV resistance (ISO7816-1 compliant)
  • Magnetic resistance (based on Nextorage internal testing)
  • Anti-Static (certified to IEC 61000-4-2 standard)

Compatibility

Nextorage is currently testing the compatibility of the B1 Pro/B1 SE Series with CFexpress Type B memory card compatible devices and has confirmed recording operation with the Canon EOS R3, EOS R5, EOS R5C and Nikon Z9. Information on other compatible devices will be updated on the Nextorage website as it becomes available.
