Discussion
After the disappointing results from the SP Elite, I wanted to know if Silicon Power was the issue, if the SP Elite was the issue, or if 3D NAND in general was the issue. To try to narrow down the issue, I picked up these cards and the SP Superior Pro 128GB.
I only have performance results from a single card at the moment…but just based on those results, it looks like this card is going to be slightly better than the SP Elite. Sequential read and random write speeds were similar, while sequential write and random read speeds were improved — about 40% better in sequential write speeds, and about 80% better in random read speeds. In terms of overall performance, this puts it just slightly above average.
On the endurance testing front:
- Sample #1 was doing just fine until it got to round 2,031, when it began experiencing a couple of I/O errors. After just the second reset attempt, it stopped responding to commands altogether.
- Sample #2 has not yet reached the 2,000 read/write cycle mark. It is currently expected to get there sometime in May 2025.
- Sample #3 is still in the package, waiting to be tested.
