Nextorage NX-B1PRO Series 660GB CFexpress Type B Memory Card VPG400 with High Read and Write Speed

The Nextorage NX-B1PRO Series PCIe NVMe 1.4 CFexpress Type B Memory Card enables optimization for professional filmmaking and maximizes the potential of the latest cameras while it maintains the quality of the image as well as stability of its performance. It comes in a 660 GB capacity.
Extreme 8K Recording
Nextorage NX-B1PRO Series provides read speed of up to 1950 MB per second near-max theoretical speed of CFexpress Type B, writing speed up to 1900 MB per second for faster buffer clearance and RAW/8K video recording at high bitrates.
Minimum Sustained Write
A minimum sustained write speed of 1800 MB per second supporting VPG400 (guaranteed minimum sustained write speed of 400 MB per second, 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. VPG400 is defined by Compact Flash Association. VPG stands for Video Performance Guarantee. It guarantees 400 MB per second sustained write speed when a camera records data with VPG400 manner. Canon EOS R3, EOS R5, and EOS R5C support VPG400 video recording. Since Canon recommends to use CFexpress supporting VPG400, Nextorage strongly recommends to use NX-B1PRO series.
Dynamic Auto Power Save
The NX-B1PRO Series CFexpress Type B card is equipped with Nextorage’s Dynamic Auto Power Save, a power saving system that reduces 68 percent power consumption in video recording compared to non-equipped pSLC CFexpress cards - contributes not only to saving the camera’s battery life, but to maintaining sustained write speed by preventing thermal throttling. Thermal throttling a control function that suppresses the transfer speed to prevent thermal runaway. Dynamic Auto Power Save prevents the cards from generating heat, which makes it possible for mirror-less cameras to record up to 1.74 times longer while writing RAW images/videos/media unlike other generic CFexpress Type B Cards.
Durability Tested
Exterior durability is tested in an environment compliant with Compact Flash Association regulations. It features operating temperature resistance of 14 to 158 degree-F. It is shock resistant, X-ray resistant, and UV resistant. It has magnetic resistance and is anti-static.
Nextorage is testing the operation in various recording modes with the latest high-end cameras.
