The equipment has good performance. Read speed of eMMC is up to 115 MB / s. And it can write data up to 86 MB / s. To extend the memory, a SD slot is provided. You can use the SD card completely hidden. I bought an SD card from Sandisk Extreme with 64GB storage space. The ratings can be reached on Chromebook. Write: 56 MB / s read and 60 MB / s. The installation of Linux systems is possible. One can also compile software package itself and easy to use. One should not care about the lack of offline software because Android apps can be installed partially.
