Discussion
This one came about as a suggestion from a Reddit user. The manufacturer ID and OEM ID indicate that Silicon Power manufactured these cards; however, the performance characteristics don’t exactly line up with any of the SP cards I’ve tested so far: the sequential read/write speeds are pretty close to the SP Superior Pro; however, the two samples I’ve tested so far have shown wildly different random read/write speeds, so I don’t feel like it’s fair to compare them to the SP Superior Pro just yet.
On the endurance front:
- Sample #1 has survived 2,528 read/write cycles so far and has not yet experienced any errors.
- Sample #2 has not yet reached the 2,000 read/write cycle mark. It is expected to get there sometime in May 2025.
- Samples #3-#5 are still in the package waiting to be tested.
