Most digital devices have basic internal storage. Smartphones, for example, have minimal storage available on their SIM cards. Other devices like point and shoot cameras and mirrorless cameras require an external storage card – this is why SDHC cards are so important.
Firstly, SDHC cards increase the minimal internal storage capacity of certain devices. Secondly, they are vital for DSLR cameras and other types of cameras. Finally, they provide a simple means of transferring files from external devices to a computer or laptop.
SDHC stands for Secure Digital High Capacity. This specification is the next iteration of the standard SD card format and offers higher storage capacity. Where SD Cards have a maximum capacity of 2GB, SDCH cards can store up to 32GB of data.
If you need an SDHC card for an external device, check the read speed and class rating. Read speed determines how quickly files are read when interacting with the card. Class rating is also important as this partially determines transfer speeds.
