Reliable Type B card for heavy sessions
Needed a Type B card for my Nikon Z7 and this one has been steady for months. I routinely shoot 500–1,000 images per session and haven’t hit any failures or write errors. It records video cleanly and transfers quickly when paired with a good CFexpress Type B reader. No overheating and no data problems so far — I’d buy the same model again.

Pro photographer pleased with faster workflow
I gave a set to my brother‑in‑law who shoots professionally and he noticed a big workflow boost. He reported measured read/write figures around 1780MB/s and 1420MB/s in his setup, which smoothed transfers and made RAW 8K/6K/4K recording more reliable. The card’s broad device support let him use the same media across multiple bodies, simplifying gear management. Overall he found the build and performance suitable for demanding assignments.
