Samsung EVO Plus 128GB microSDXC Card Review – Performance and Speed

ATTO DISK BENCHMARK VER.3.05

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 Disk benchmark displays performance results that match that of listed specifications, 98MB/s read and 89MB/s write.

CRYSTALDISKMARK BENCHMARK VER.5.2.1

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.

Understand that CrystalDisk Benchmark is transferring samples that are highly incompressible, results of 97MB/s read and 83MB/s write are still excellent returns.

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.

Anvil confirms pretty much everything we have already seen.  If you look at the drive identification on the bottom right, you will see that it shows a Lexar pro LRW 400, this being the adapter we use to connect the Samsung card to the PC.
