Testing & Results
As a practical test, I spent many hours using my Canon Powershot SX610 HS camera and ZTE Warp Elite smart phone shooting hundreds of photos and a little more than 20 hours of 1080p video footage with both devices for about a week in the desert around Joshua Tree and surrounding area.
I spent most of it in the heat of the day where we were having low 100 degree temps for a few of the days. I tried to put the Kingston Industrial Temperature MicroSD out in the heat as much as I could while testing it. I even put the Industrial Temperature into a glass of water for a few minutes to see if it was truly waterproof. After letting it dry thoroughly, it showed no signs of damage and worked flawlessly.
But of course, what would a review be without some benchmarks? Well, that would just be boring. So, with that in mind, I set about testing the Industrial Temperature with ATTO Disk Benchmark, CrystalDiskMark, AS SSD Benchmark, and A1 SD Bench utilities. The last of which, is a smart phone benching application for Android OS.
First of all, I made sure to format the Industrial Temperature MicroSD with the exFAT file format, to be able to have files sizes larger than 4GB, which is the max single file size limitation on FAT32 format. Then I set up testing for both USB 2.0 and USB 3.0 using a Transcend TS-RDF5K USB 3.0 MicroSD/SD card reader. The initial USB card reader I was using wasn’t up to snuff, and operated only at USB 2.0 speeds, which hampered initial testing and required me to pick up the Transcend USB card reader to fully see the speeds of the Industrial Temperature MicroSD.
I also observed while testing, that if you use the SD adapter and then plug that into the card reader, it hampered performance by almost half. I recommend using the MicroSD without the adapter when possible. It didn’t hamper recording performance, however, with my Canon Powershot since it does not use MicroSD cards and must use the adapter.

We’ll start the testing with CrystalDiskMark. I used the latest version 5.1.2 x64, which is the 64bit version of the client.
The difference between USB 2.0 and USB 3.0 are pretty significant. The results are more than 3 times faster in sequential read and writes. If fast transfer speeds are important to you, make sure that you are connected through USB 3.0 especially for large files that will make use of the higher bandwidth.
With reads as high as 95.02 MB/s and writes of 49.55 MB/s, the Kingston Industrial Temperature MicroSD is living up to it’s speed ratings.
Next up, we have ATTO Disk Benchmark version 3.5.0. ATTO Disk Benchmark tests the MicroSD card at varying transfer sizes from 512 bits, to 64MB.
Again, we notice a huge difference between USB 2.0 and USB 3.0 transfer speeds. ATTO gives you a good idea of what kind of transfer speeds you will see depending on file sizes. A bunch of small files are going to transfer relatively slow, compared to large files.
Once you hit the 64KB range the Kingston Industrial Temperature MicroSD comes alive and starts to show the speeds it’s capable of sustaining. We see peak write rates of about 52 MB/s at the 16MB block size, and peak read rates of about 95 MB/s around 12MB and 24MB block sizes. This is pretty much in line with what CrystalDiskMark reported.
Now we have AS SSD Benchmark version 1.9.5986.35387. AS SSD Benchmark is similar to CrystalDiskMark in that it tests sequential read and write, as well as testing random read/write of 4K blocks with a 1GB file transfer.
At this point there is no surprises. We know USB 3.0 is going to be much faster than USB 2.0. Although this time we seem to have an anomaly with the sequential write speed on the USB 3.0 bus. With 64.95 MB/s this is quite a bit faster than the other two benchmarks. I did the test a few times with the same results. The sequential read speed of 90.73 MB/s is right in line with the other two tests.
I also obtained a somewhat similar result in the next test, A1 SD Bench version 5.1 on my ZTE Warp Elite smart phone.
Oddly enough my smart phone was slower at reading the Kingston Industrial Temperature MicroSD than it was at writing to it. With a read rating of 58.55 MB/s and write rating of 59.43 MB/s it leaves me wondering if the last two benchmarks were using some kind of compression to give it an effectively higher write speed? In both situations I ran the tests again to confirm the results, and they were consistently the same. I made sure to reboot both my phone and computer, to ensure that no caching was involved in the test results.
So, there you have it. The Kingston Industrial Temperature MicroSD is rugged and fast. On the next page I’ll give you my final thoughts and conclusions.
