"WebIn these applications, the QSPI is not bit-bung, and is therefore four times faster. For your specific microcontroller (and many small 8-bit MCUs), you are correct and you will be better off with a regular x1 SPI flash. With many many microcontrollers, applications processors, and FPGAs, there is hardware support for x4 SPI and it is far faster. " - Qspi and spi
