Nextorage B3 AE CFexpress 4.0 Type B Reviews

Passed a stress test (Also)

Rated 5 out of 5
Date: 2026-05-04

I just recently purchased two more of these cards, and I am happy with them so far for my Nikon Z6III and ZR cameras. The capacity is great for my day-to-day, and it so far has not shown any problems with overheating.

Works well with Canon R1, R5II

By Ron
Rated 5 out of 5
Date: 2026-02-20

I've logged at least 100,000 RAW/CRAW frames on this card in both the Canon R1 and R5II since Sept. 2025 without issue at 40 or 30fps, respectively. This card, as a 4.0 version, is way faster than either camera. Only regret is I only bought one back in September when it was on a one-day flash sale for almost half of its current selling price.

Is the Nextorage 1TB NX-B3AE CFexpress 4.0 Type B Memory Card compatible with Nikon Z9?
Asked by: An
Yes, the Nextorage 1TB NX-B3AE CFexpress 4.0 Type B Memory Card is compatible with the Nikon Z9 Mirrorless camera. CFexpress 4.0 is backward compatible with CFexpress 2.0. This means the card will operate at CFexpress 2.0 speeds when used in the camera, but it will still function reliably and support high-performance tasks like 8K video and RAW burst shooting, thanks to its VPG400 certification (guaranteeing a minimum sustained write speed of 400 MB/s).
