There are three main differences:
1. Consumer CF cards can only be used as a removable disk, whereas Industrial CF cards are used as a fixed disk.
2. Temperature conditions:
Industrial CF cards can be used between -40°C to 85°C.
Consumer CF cards can be used between -25°C to 85°C.
3. Flash types:
Industrial CF cards use SLC (single level cell).
Consumer CF cards use MLC (multi-level cell).
Therefore, industrial CF cards provide better stability and endurance in general.
