- CFexpress Type B: Has a larger form factor of 38.5mm x 29.8mm x 3.8mm.
- CompactFlash: Comes in a type I (43mm x 36mm x 3.3mm) and type II (43mm x 36mm x 5mm) form factor.
Price: What’s the Cost?
Price is a significant consideration when choosing a storage card.
- CFexpress Cards: Generally more expensive than CompactFlash cards, especially for higher capacities.
- CompactFlash Cards: Offer a more budget-friendly option, especially for lower capacities.
Key Points: Making the Right Choice
Ultimately, the choice between CFexpress cards and CompactFlash cards depends on your specific needs and requirements.
