We have seen a consistent innovation in storage devices with respect to speed, size and storage capacities. The storage devices have now become more faster and are capable of storing large capacities in just small piece. One such storage devices are microSDs which are nothing but removable flash memory cards usually used in mobile phones. With the introduction of microSDHC/SDXC cards, users are now offered higher and extended storage for mobile phones. These memory cards are identical to standard microSD cards but are recognized only by microSDHC or microSDXC devices. However, They can be used as full-size SDHC/SDXC cards together with the included adapter. Well, our review focuses on Kingston’s Class 10 UHS-I microSDHC/SDXC card. The name itself suggests that the use of speed “class” rating that guarantees a minimum data transfer rate for optimum performance with devices that use microSDHC/SDXC. This means the Class 10 UHS-I indicates that minimum data transfer rates of 10MB/s which makes them capable of delivering great HD video recordings.

Kingston Class 10 UHS-I microSDHC/SDXC 128GB Review
Kingston Class 10 UHS-I microSDHC/SDXC has been introduced to improve performance and increase storage on smartphones, tablets, cameras and other portable devices. The UHS-I technology enables higher bus interface speeds to optimize playback and transfer of files with “10” suggesting 10MB/s minimum data transfer rate and comes in storage capacities from 4GB to 128GB along with lifetime warranty and free technical support. Check out the review of Kingston Class 10 UHS-I microSDHC/SDXC 128GB card:
– Packaging and Looks
The Kingston Class 10 UHS-I microSDHC/SDXC comes with the simple Kingston’s packaging with the back detailing the highlights. The icon at the bottom right indicates the lifetime warranty. The package includes a Kingston SD Card Adapter along with the microSDHC/SDXC card. The 128GB microSDXC card comes with the marking of UHS-I and Class 10 marking indicating its speed class.
– Performance and Testing
Well, we have conducted a test on the Class 10 UHS-I microSDHC/SDXC to measure the performance. In order to measure the performance, benchmarks are obtained for the Class 10 UHS-I microSDHC/SDXC 128GB card using ATTO Disk Benchmark, Crystal Disk Mark and SpeedOut.
- ATTO Disk Benchmark
ATTO has created a widely-accepted Disk Benchmark freeware utility to help measure storage system performance. The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. It measures your storage systems performance with various transfer sizes and test lengths for reads and writes.
Atto Disk benchmark tested on USB 2.0 laptop has the Read Speed as 29.5MB/s and Write Speed as 20MB/s.
- Crystal Disk Mark
CrystalDiskMark is designed to quickly test the performance of your hard drives and allows user to measure sequential and random read/write speeds.
Crystal Disk Mark benchmark tested on USB 2.0 laptop has the Read Speed as 27.7MB/s and Write Speed as 20.6MB/s, which is almost similar to ATTO Disk benchmark.
SpeedOut is a small and portable software tool which reveals the reading and writing speed of your USB flash drives
There is some small deduction in speed while testing with SpeedOut. The SpeedOut benchmark tested on USB 2.0 laptop has an average Read Speed as 29.5MB/s and Write Speed as 20MB/s.
However, we have not yet tested this Kingston microSDXC on a USB 3.0 device, but as per company claims and other reviews it fairs far more better than USB 2.0. The Kingston’s Class 10 UHS-I microSDHC/SDXC USB 3.0 performance has Read Speed more than double that of USB 2.0 i.e. Read Speed as 79MB/s and Write Speed which is near to USB 2.0 of about 26MB/s.
Well, Kingston’s Class 10 UHS-I microSDHC/SDXC card has an excellent read/write performance and can be considered as a best options especially when you are looking for large capacity microSD. Looking to see your views on this microSD in the comment box below. Stay tuned for more updates.
