User Experience & Conclusion
Taking parts of our storage device testing suite, we will be measuring the potential performance of the KingstonÂ SDCX10/64GB using ATTO Disk Benchmark and Crystal DiskMark as well as testing with our standard real-world miscellaneous files copy test (3.1GB of random files ranging from 1KB to 8MB with a couple of large files interspersed among the directories).
For these Â tests we will be using Kingston’sÂ MobileLite Gen 3Â USB3.0 card reader.
Just like the 64GB we reviewed before, Kingston doesn’t state the peak rated performance we can expect from the Kingston 128GB microSDXC card other than it should have a baselines performance of 10MB. From the benchmark above we can see that the 128GB MicroSDXC Kingston card gives us a peak 79MB/26MB read/write performance. This is almost double of the 45MB/15MB we saw from the 64GB variant showing us that Kingston has not only increased capacity but has improved performance as well.
Complementing our benchmark prior is Crystal DiskMark which shows us similar figures in its results.
Transferring files to and from our system we clocked in the Kingston 128GB microSDXC four and a half minutes for our miscellaneous test files and just under 10 minutes for our large file copy test.
Moving over to mobile, most modern high-end smartphones will support 128GB capacities out of the box specifically last-year’s flagship models like the LG G3. Check with your device’s manufacturer to ensure compatibility. In our case, the LG G3 happily accepted our 128GB SDXC card without issues. As seen above, the maximum capacity 118GB, same with our Windows capacity. With some devices capable of shooting 4K UltraHD videos, the capacity is a welcome benefit and with our G3 shooting at 4K we noticed butter smooth capture and playback.
Current market prices puts at around $120 with some sale prices going as low as $100. Looking around we’re seeing similarly specced 128GB models from competitors with some reaching below the $100 mark. This is a critical point for the consumer in their decision making but ultimately, it should boil down to brand preference and customer support.
That said, Kingston offers good performance at an reasonably price range. If you’re looking for a boost in your storage capacity for your mobile and multimedia device, the Kingston Digital 128GB MicroSDXC Class 10 memory card gives you both flexibility and performance backed by tested customer support.
Backed by a lifetime warranty and with an impressive price tag, we award theÂ Kingston Digital 128GB MicroSDXC Class 10 Flash Card (SDCX10/128GB) our B2G Silver Award and B2G Value Award.
