While copying large files in the ‘File Manager’ of Kodi.
File copy operations have the following sequence: SSD_read -> USB_2.0_port -> RAM_memory -> USB_2.0_port -> SSD_write. Total reading speed + writing = 80 MB/s.
Although the SSD can reach read speeds of 500 MB/s and write speeds of 450 MB/s, the limitation is found in the USB 2.0 port of Mecool KIII Pro.
