Discussion

It wasn’t until pretty late into this project that I realized that PNY hadn’t been represented in my survey thus far. I hadn’t managed to find any PNY cards on AliExpress — at least, not any PNY-branded cards — so I had to look at what Amazon had. I chose two models: this, and the Premier-X 128GB. As you may have guessed from the pictures, this card was offered in a three-pack — so the price you see above is divided evenly between the three cards.

Performance-wise, this card scored slightly above average in all performance metrics, with the exception of random write scores — where all three samples scored more than one standard deviation above average, almost nearly two standard deviations above average. The worst of the three random write scores would put it in the 92nd percentile. Not bad!

These cards bear the Class 10, U3, V30, and A1 performance marks. All three samples performed well enough to qualify for all of these marks.

All three samples are currently undergoing endurance testing. None have yet reached the 2,000 read/write cycle mark; they are currently expected to reach that point sometime in September 2024.
