Samsung Pro microSDXC UHS-1 U1 Card Review (64GB)

FLASH MEDIA TEST PROTOCOL

In order to test the rated speeds of the card we choose to use a few popular synthetic benchmarks which include ATTO, CrystalDiskMark, and Anvil Storage Utilities Professional. Not only are we going to use these benchmarks, we are going to run a comparison against other cards I have in my bag and test in a real world use scenario. This should give us enough to confirm the rated specs and give us a more in-depth view on how it performs.

Kingston MobileLite G3

To connect the microSDXC card to our computer we have the Kingston MobileLite G3 USB 3.0 card reader. It is a compact and simple plug-and-play card reader that allows for USB 3.0 transfer speeds for any SD / SDHC / SDXC and microSD / SDHC / SDXC cards. It is a pretty good buy especially at only around $10 and will allow us to test the Kingston Ultimate at up to its max rated speeds.

ATTO DISK BENCHMARK VER. 2.47

ATTO Disk Benchmark is a relatively easy-to-use benchmark tool. ATTO Disk Benchmark relies on testing different file sizes with highly compressible data.  Although this is not the best representation of media files which are, for the most part, highly incompressible, it is a good start and is still the main mechanism most manufacturers use to determine their product specifications. In our testing, we have left the benchmark settings to default.

ATTO verifies the rated 90MB/s read speeds, but we are around 2.2MB/s shy when it comes to the rated write speeds. The max write speed ATTO provides is 77.8MB/s

CRYSTALDISKMARK BENCHMARK VER. 3.0.3

Crystal Disk Mark is visually straightforward and is used for measuring the speeds at which your storage device reads and writes with random, mostly incompressible, data. Random data is more consistent with everyday use of a computer, such as transferring videos, pictures and music. Thus, this benchmark will be a better representation of speeds to expect on a video or stills camera over ATTO.

Crystal Disk Mark is showing us the same results as ATTO. The max read speed is 90MB/s and the max write speed is 77.66MB/s. Again, just shy of the rated write speed.

ANVIL’S STORAGE UTILITIES PROFESSIONAL 1.1.0

Anvil’s Storage Utilities is the best software program available for benchmarking flash media.  Not only does it give an accurate look at transfer speeds and throughput, but also, it goes even further by identifying file sizes, disk access times, as well as system and device identification. It even has many extra features such as endurance torture testing and a TRIM button feature to manually trigger TRIM on supported devices.

Finally, Anvil’s Storage Utilities shows a max of 85.8MB/s for the read and a max of 70.28MB/s for the write. The speeds are slightly slower in this benchmark due to it testing fully compressed data.

Its a really bad idea to buy any storage media off ebay, as its flooded with fake stuff.Its all fun and games until you realize your 64GB card is really just 4GB with hacked capacity.

Seriously a lot of fakes. I bought from fry’s and it was a fake Samsung. They refused to return because I didn’t have the box like it mattered! but really a lot of fakes.

Is it good enough to record 4k videos on Galaxy s5?

Is there anyway that you can do a benchmark with A1 SD? This would really help for people who want to use them in phones. Random read and write are what’s important!

Sean, You should use Kingston MobileLite G4 – significantly better speeds.
