SANDISK 1TB CFexpress Type B Reviews
Fast and reliable memory card
By Steve
Rated 5 out of 5
Date: 2026-10-06
The Sandisk 128 GB Extreme Pro CFexpress 4.0 type B is my first foray into CFexpress memory. I have used it for still photography primarily with my Canon R5 mrk II and the performance has been great. My limited use of the card with video also has been good. It seems very fast and reliable so far. Download speed also seems fast. I am pleased enough to get another Sandisk CFexpress should I find one at a good price. I would recommend this card. B&H was prompt with shipping, and the card, along with card reader, were packaged nicely.
Faster than the other cards I have.
