Review on 🚀 High Speed Silicon Power 64GB 3D NAND MicroSD Card with Adapter - Boost Your Storage! by Dezz Watson

This review is about two packs of 64GB cards. The packaging is good and similar to other cards with full size SD adapters. They have similar performance to Samsung EVO Select (U3 rated) and Sandisk Ultra (U1/A3 rated) with the same capacity I tested. Sequential read/write speeds were around 93/60 MB/s. Rated speeds are slightly higher at 100/90, the difference may be down to my card reader, although I'm ok with that. As expected, random access was slower with reads >6 MB/s and writes >2 MB/s, similar to other A1-rated cards I've tested. Many non-A1 rated cards are much slower for random access, and write speeds are sometimes less than 0.1MB/s. They should work reasonably well in most applications, including those with a significant amount of random access like smartphones and single board computers like the Raspberry Pi. Can't comment on durability yet, but other Silicon Power SD cards I own work still perfect even after years of regular use.
