The improved standard of flash memory UFS 3.0 can almost double the speed of modern smartphones. At least, this is evidenced by the latest data from memory tests.
On the eve of the web, there was a snapshot of the result of the verification by the AndroBench benchmark of the UFS 3.0 memory. If you believe the numbers, the standard writing speed reaches 1800 MB / s, and the reading speed is close to 2280 MB / s. Comparing these figures with UFS 2.1, one can only envy the future owners of smartphones with an improved memory standard.
Previously, there was information that the new standard is supported only by Samsung, and therefore it is quite possible that the new Galaxy S10 may well receive UFS 3.0 memory.
