What I Check Before Buying
Before I choose one, I always make sure the card matches my device. I check the SD card type, such as SDHC or SDXC, because not every device supports every format.

Device Compatibility Is a Must
I never assume every 256GB card will work in every device. Some older cameras, laptops, or tablets may not support this capacity. I always check the manual or product specifications first. This saves me from buying a card that my device cannot read properly.
