You are using the UHS-I bus, which allows a maximum of 104 MB / s, but thank you “Proprietary technology“Theoretical limit is exceeded. Other manufacturers, such as Lexar, do the same. In the footnotes, Samsung points out that reading devices must support this increased performance.
Available in the Pro Plus option with a USB adapter that supports 160 MB / s for an additional charge.
Micro SD cards with a UHS-II interface can work even faster, with peaks of around 300 MB / s, but they are rare and relatively expensive. PCI Express is expected to go on SD cards next year: first-generation SD Express memory cards are expected to reach nearly 900 MB / s.
