Galaxy S8: Different storage facilities ensures for criticism

in the United States, apparently Galaxy-S8 models are sold whose storage facilities not which of Samsung originally advertised UFS 2.1 standard. Instead of the type UFS 2.0 to use the slower memory comes in the models in question. According to recent findings, only the Galaxy S8 is affected by the problem. So far no models with different memory configurations have surfaced in Europe.

only before a few days the Chinese manufacturer Huawei, because of the same problem got into the focus of interest. The current models P9 and P10 are also available with different memory types. Instead of the promised UFS 2.1 store, Huawei eMMC uses sometimes the even older type 5.1. On the Web page, indicating that the P9 with UFS-2.1 storage is equipped, is, however, the “100% faster data transfer rates than eMMC 5.1 chips” offers. Differences in features involve also the memory. Huawei LPDDR3 or LPDDR4 memory used depending on availability. Basic for this approach Huawei mobile boss Richard Yu delivery bottlenecks were.

memory: performance counts

not without reason the Smartphonehersteller take great efforts to improve the performance of their devices with each new generation. Just access the data store is an important indicator in this regard. Finally, the Speichersubystem the slowest component is by all relevant performance factors. The data transfer rates move in terms of MB / s, while CPU, GPU and RAM can process data with GByte/s. Desktop users also know the phenomenon. Who, for example, replaced the magnetic disks in his PC by a high-performance SSD will be noted that this measure in practice often brings a much higher performance gain than a CPU update.

 memory performance of smartphones: UFS 2.1, UFS 2.0 and eMMC (graphic: even when smartphones has rapidly evolved in recent years. So, the Galaxy S8 with UFS-2.1 memory compared to the LG G4/eMMC offers several times in performance. And this not only for sequential access, but also much more important for the practice of random read / write access. Also in comparison to the last year’s flagship Galaxy S7 with UFS-2.0 memory, Samsung’s new smartphone offers considerably more power.


If you can always feel the appropriate Performanceunteschiede in practice, not time. In any case, you should pay as a consumer for something that it has not received. Even if the described cases relate to the United States and China and in Germany probably no devices of which are affected, consumers should carefully examine their just purchased product and may return if the equipment does not conform to the manufacturer’s instructions.

to find out which Flashchips for the data store are entering following command in a terminal-emulation:

  • cat / proc/scsi/scsi

Alternatively you can enter command also of the ADB shell. Then, the syntax is:

  • adb shell cat / proc/scsi/scsi

the following output lists the storage model used. Twitter user @yao_yunfan when a table is published, the common memory chips including supported memory type shows.

that performance of the storage subsystem can you check Android with AndroBench .
