As digital cameras evolve, so do the related accessories. An important piece of equipment every photographer must own is an SD card. In most instances, it is beneficial to have two or three SD cards as backup.
The latest iteration of SD memory card is the SDXC – this stands for Secure Digital Extended Capacity. Originally announced in 2009, the SDXC specification allows cards to support up to 2TB of storage. This far outperforms SDHC which has a maximum capacity of 32GB.
For the professional photographer, SDXC cards are an excellent choice. As a minimum, these cards usually have 64GB or more of storage – 128GB is common. This provides superb flexibility and allows photographers to store much more on their cameras.
When choosing SDXC cards, you must consider the following – storage capacity, brand, read speed, class rating, and price. Read speed and class ratings are particularly important as this affects how quickly photos are transferred to external devices.

Improve Your Camera Storage Capacity with an SDXC Card
These cards are the best available on the market. There is an SDUC variant too which has storage over 2TB, but unless you are recording hours of HD video, an SDXC card should be sufficient for most photographers’ needs.
We advise purchasing two to three SDXC cards for redundancy and as a safeguard. This ensures that if one is damaged or misplaced, you still have spares to use. Also, don’t forget to regularly transfer and back up your photos from your SDXC cards.
Finally, it is beneficial to format your SDXC cards occasionally to ensure they remain faultless and have a smooth operation.
