Buying Guide

Here are some common factors to consider when shopping for this CFexpress type B memory card.

Memory Card Type

Memory cards are categorized by their memory capacity. There are two types of memory cards: CFexpress type A and CFexpress type B. The main difference between these two is that a CFexpress type B card can support higher speeds, but the data transfer rate is lower than a CFexpress type A card.


The speed of a memory card refers to how quickly it reads and writes data from the memory card to your device. The faster the speed, the better your device will perform when you use it with this particular memory card.

Storage Capacity

The storage capacity refers to how much information you can store on your memory card at once before it becomes full (or nearly full). For example, if you have a 16 GB CFexpress Type B Memory Card, it’ll take around 10 minutes to fill up completely if there is only 1 GB left on it (assuming no other files are being stored).
