SanDisk storage, ranked by cost per terabyte

SanDisk is the dominant name in removable flash, and its catalogue reads like a photographer's kit list. The Extreme, Extreme PRO and Ultra microSD and SD cards are the default choice for cameras, drones and handhelds, with CFexpress covering high-bandwidth cinema and mirrorless work. On the everyday side, SanDisk's Ultra and Extreme USB flash drives are some of the best-selling sticks made, and its portable external SSDs bring rugged solid-state storage to the field.

SanDisk is owned by Western Digital but kept as a separate brand here, reflecting its distinct camera-and-mobile focus. On value, memory cards and USB flash sit at the high end of cost per terabyte across the whole site — you are paying for miniaturisation, ruggedness and the certified sustained write speeds that stop a camera dropping frames, not for bulk capacity. Within that category, SanDisk is competitive and, crucially, trustworthy in a market plagued by counterfeits. Buy genuine, match the card's speed class to your device, and compare the live, SanDisk-filtered catalog below sorted by real $/TB.
