SanDisk Extreme Pro SDXC UHS-II 256GB vs Samsung T7 Shield Portable SSD 256GB
Verdict: The Samsung T7 Shield outperforms the SanDisk Extreme Pro card in raw transfer speeds (1,050 MB/s vs 300 MB/s) and adds IP65 ruggedness, making it the superior choice for on‑the‑move backups (Samsung spec, Tom's Guide, TechRadar). However, the SanDisk card remains indispensable for cameras that only accept SD cards, delivering industry‑leading UHS‑II performance in a tiny form factor (SanDisk product page). For users who need a portable, high‑speed drive for laptops and phones, the T7 Shield is the clear winner; for photographers locked into SD‑only gear, the Extreme Pro card is still the best fit.
Winner: Samsung T7 Shield Portable SSD 256GB
SanDisk Extreme Pro SDXC UHS-II 256GB: 6.5/10
