The speed at which CFExpress media is capable of reading/writing data seems to be expanding nearly exponentially. With its new B1 Pro Series Type B CFExpress media card, Nextorage is claiming the world’s fastest design with read/write speeds up to 1950 MB/s and 1900 MB/s respectively.
With VPG400 support, the B1 Pro series is guaranteed to not drop below 400 MB/s on constant read/write speeds, but Nextorage claims that their internal testing indicated nearly five times that speed in bursts.

Nextorage has also proclaimed that the cards were tested on Canon EOS R3, R5, and R5C mirrorless cameras, as well as the Nikon Z9.
The cards have been optimized for 8K video with the highest bitrate and Raw shooting codecs being a chief focus.
The card rivals the Lexar Professional Diamond CFExpress Type B card which is slightly faster in peak reading speed at 1990 MB/S, but slower in writing at 1700 MB/s. So being able to claim the “world’s fastest” mantel is somewhat of a matter of interpretation.
Moreover, Nextorage says that the cards have a unique Dynamic Auto Power Save technology that uses up to 68 percent less power and limits the amount of heat generated when the card is being used.
The cards also maintain stable writing speeds without thermal throttling to affect transfer speeds.

The B1 Pro SE card series is also available with rated read/write speeds of 1950 MB/s and 1100 MB/s respectively and is designed for still image photography which requires less performance than capturing 8K videos and above.
However, sports photographers are likely to want the faster write speeds of the B1 Pro when shooting high-speed bursts.
Both cards come in storage sizes ranging from 165 GB to 1330 GB and promise stable video recording with durability in a variety of harsh weather conditions, and is rated EIA, IEC, and ISO compliant for being shockproof, X-ray resistant, and anti-magnetic. The card is also ultraviolet resistant.
Currently, the Nextorage B1 Pro Series Type B CFExpress media cards are only available in Japan but are expected to be released on Amazon in late December 2022.
The retail price, based on the current Yen to dollar exchange rate, is listed for the B1 Pro as 165GB, 330GB, 660GB, and 1330GB capacities for roughly $192 (165GB) $430 (330GB), $715 (660GB) and $1430 (1330GB).
Meanwhile, the B1 SE is available starting at $99.99 for the 128GB and $139.99 for the 256GB version. All cards come with a 5-year warranty.
