Discussion

I think this is one I found out about after perusing through SanDisk/Western Digital’s online store and seeing what options they had available. And since I seem to be reviewing everything else of SanDisk’s, why not add this to the mix?

Performance-wise, SanDisk set the bar pretty low on this one — there are no speed claims on the package, and the card itself only bears the Class 10 and U1 markings. It easily met the requirements for both of those markings. All performance metrics came within one standard deviation of average, with sequential write speeds being the worst of the four scores. Overall, it performed about as well as the Samsung EVO Plus 32GB.

All three samples are currently undergoing endurance testing. None have yet reached the 2,000 read/write cycle mark. Samples #1 and #2 are expected to get there sometime in August 2024, while sample #3 is expected to get there sometime in July 2024.
