Theoretical SPI-RAM access speed is ~40MB/s.
In final application, for example in MicroPython firmware, SPI-RAM access speed is is ~14 MB/sec.
The access is cached in internal RAM buffer (same as Flash access) and practical results shows it is quite usable if it is used in a way it is suposed to be used.
In the typical MicroPython application there is often no difference if the heap is on internal RAM or external SPI-RAM.
What’s continuous, random read, write speed for SPIRAM vs sram?
