microSD-card: Samsung EVO plus 256 GB 2017 in the practice test

Samsung has its microSD models updated. The maximum reading rate increases at the flagship EVO plus 256 GB but only slightly from 95 to 100 MByte / s. And the height of 90 MB / s write performance has become not better compared to its predecessor. The write rate of the smallest variant at least 10 to 20 MByte / s

in addition, the manufacturer has its microSD portfolio on the series EVO plus and PRO plus reduced. The EVO plus is available in capacities of 32, 64, 128 and 256 GB, where the versions with 128 and 256 GB have the same data transfers. The 64 GB version offers the same write performance as the larger models with 100 MByte / s. You can save data maximum only with 60 MByte / s.

PRO plus is available in versions with 32 and 64 GB read / write speeds of 100 and 90 MB / s all models are supplied with an SD adapter.

distinction between old and new EVO series

it will take a while , until the old models from the trade are completely gone. Because both series with EVO plus are known, they can be easily confused. However, there is a change in the spelling. While the old series with “EVO +” is labeled, even appears on the new packaging and the product “EVO plus” . The + sign is so advertised on the 2017er models. Also, the respective products wear also a different model numbers. Instead of “DA / EU” are the new versions with “GA/EU” marked

performance Samsung EVO plus 256 GB

as usual to provide the transfer rates specified by the manufacturer only under favourable conditions. Also it depends on also, with which these were determined measuring method, say benchmark program. The EVO plus 256 GB achieved under one surface of Windows 10 and a Pro 2 maximum performance by 90 MB / s sequential read-only . When writing about reaches 80 MB/s .

in Android it looks however differently. This might be also on the different benchmark programs. Under Windows, the tool comes Crystal DiskMark used, while Android AndroBench is used. For each test run, the microSD card reformatted under the respective platform and then a restart is performed. Also are deleted the application data and the cache of AndroBench before each run. To minimize the influence of measurement outliers, the benchmark test is repeated three times. The average values of the measurements can be found in the table.

also internal memory performance is calculated with AndroBench. This is an assessment, whether you would like to use the microSD card as “internal memory”, allows what is offered since Android 6.0 by some smartphones. Because the performance penalty is clear, the greater the performance difference between internal and external memory, the greater, when it brings together both memory.

benchmark results under Android 7

as can be seen on the basis of the benchmark table, the performance of Samsung EVO plus 256 GB is dependent on the performance of the platform. For the test are Galaxy S7, LG G4 and Galaxy S4 available. The devices come from the years 2016, 2015 and 2013. This way, one can roughly estimate the performance of the microSD card is as high, if they are used with a Smartphone with similar manufacture date.

while the EVO plus 256 GB in conjunction with the Galaxy S7 and the LG G4 made a read / write rate for squentiellen access between 75 and 78 MB / s or 38 to about 44 MB / s is the Galaxy S4 only to 17.61 respectively 15,41 MByte/s. The cause should be first and foremost a worse system connection of the microSD card. And surely also the weaker processor (Snapdragon 600) plays a role. However, the values of the internal memory, that the used CPU at least is able to process transfer rates of close to 100 MByte / s show.

the Performanceunteschiede be not so violently during the random read / write access. Although the Galaxy S4 in conjunction with the EVO plus 256 GB 3.66, 2,13 MByte / s also delivers the lowest values of the three test candidates. But not be Galaxy S7 and LG G4 something over 5 and approximately 2.5 MB/s is the case as far away as in the sequential access.

conclusion: Samsung EVO plus 256 GB

Samsung delivers microSD cards that are well suited for a memory of a Smartphone with the new EVO-plus series. On the map, full HD videos or 55.200 photos fit about 12 hours 4K-UHD-Videos or 33 hours.

However one should consider himself well, if you format the microSD card as internal storage or applications installed on it. The performance differences between internal memory and microSD card are substantial with newer smartphones. The internal memory of the Galaxy S7 is more powerful when the random write access important for the everyday performance, for example, less than 20 times. It is therefore understandable that the option to configure the microSD card as internal memory, not even offered by Samsung the Galaxy S7.

the performance of the EVO plus 256 GB is sufficient for use in high-resolution action cameras. The test represents expected no challenge with Yi 4 K, which achieves a maximum data rate of 60 MBit/s, i.e. 7.5 MByte / s, for the EVO plus 256 GB. Also with the successor of Yi 4 K +, the first action camera at all 4K-Aufnahmen with 60 fps allows and thus provides for a maximum data rate of 15 MB / s during the recording, the EVO plus 256 GB should cope well.
