Samsung delivers Galaxy S8 with both ufs 2.1 and ufs 2.0
Samsung appears to be supplying the Galaxy S8 and Galaxy S8+ with both ufs 2.0 and ufs 2.1 nand, while ufs 2.1 was initially mentioned as a specification. For the time being, the versions with Exynos-socs seem to have the faster ufs 2.1.
Originally, Samsung explicitly mentioned the presence of ufs 2.1 on its global Galaxy S8 site, but that specification has since been removed. Owners of the device compare their storage specification on XDA and Reddit, among others. For the time being, it seems that all models with Exynos chips have ufs 2.1 memory from Samsung itself and the Galaxy S8 + with Snapdragon has 835 ufs 2.1 nand from Toshiba. This would make the Galaxy S8 with Snapdragon the only model where Toshiba ufs 2.0 has been found. Users can identify their memory type with the command ‘cat /proc/scsi/scsi’ in the Terminal Emulator app, XDA describes.
Ufs 2.1 is faster at about 700 to 800MB/s than ufs 2.0, which gets about 500 to 600MB/s. In practice, users should notice little of this difference, but it does show up in benchmarks. Samsung does not use emmc in the Galaxy S8, which is noticeably slower.
The findings follow similar reports about the Huawei P10. The manufacturer supplies the model with ufs 2.0, ufs 2.1 and emmc 5.1 storage, without consumers being able to know in advance what memory their device has. The manufacturer apologized for the course of action. The manufacturer cited delivery issues as the reason for using different types of flash storage. There have been nand shortages for months, resulting in high prices.
