Discussion
This card was pointed out to me by a Redditor after someone shared this page to r/SBCGaming (thanks, u/_master_!). Seeing as how it was in my price range, I figured “why not?”
My initial impression is that this is simply a rebranded SanDisk Extreme PRO 128GB — just based off the fact that (a) the product name (in the CID data) has the same “SR” prefix as the SanDisk Extreme PRO 64GB, and (b) the product revision (also in the CID data) is the same. In performance tests, it did about the same as the other SanDisk Extreme PRO’s, except for sequential write speeds — where it outperformed all of them, putting it (as of the time of this writing) in the 97th percentile for sequential write speeds.
On the endurance testing front:
- Sample #1 has survived 2,484 read/write cycles so far and has not yet experienced any errors.
- Samples #2 and #3 are still in the package waiting to be tested.
