The SanDisk Extreme effectively matched the Pro Plus in a few of our sequential tests, but that was partly due to us only being able to secure the 256GB model, which is higher-rated than the 128GB version.
It's a fine choice if you see it on sale at a reputable seller
but it's broadly slower than our top pick and often costs more
