Discussion

This card, along with the PNY Elite-X 64GB, are the first PNY-branded cards that I’ve purchased as part of this project — which, honestly, seems like an oversight on my part. (How could I forget about PNY?)

Performance-wise, this card performed pretty well — it looks like it doesn’t support the enhanced speeds that SanDisk’s cards do — which meant that sequential read speeds were only slightly above average — but it did exceptionally well with sequential write speeds, putting them in the 95th percentile. Random read and write speeds were all more than one standard deviation above average, with two of the three samples getting random write speeds that were more than two standard deviations above average. The worst of the three random write scores would put it into the 87th percentile in this category, while the worst of the random read scores would put it into the 85th percentile. In fact, the worst performance measurement between all three samples would put this card into the 84th percentile.

This card carries the U3, V30, and A1 markings. Additionally, the package carries the Class 10 marking. All three samples performed well enough to qualify for all of these markings. (Well done, PNY!)

All three samples are currently undergoing endurance testing. None have made it to the 2,000 read/write cycle mark yet. All three are currently expected to reach this point sometime in January 2025.
