Re: SD card vs flash drive, speed?

OK. Using a 128K for a r/w buffer still allows an additional 380+K. Or make it 256K buffer which still allows for an 256K of additional storage. Still better than what's in there now.
I'm an embedded engineer (for 40 years) and it particularly troubles me that so much flash memory is not utilized. It's always treated as a precious resource. If anything, it could be used as a virtual flash file system if not used for the uPython OS.
Moving forward, embedded MCU's are only going to have increased memory and performance. The new PyBoard in beta has an M7 core with a large memory footprint, eventually moving to 1M SRAM in place of relatively slow Flash. It would be a shame if fast SRAM were not fully utilized.
