Hi Alan, yes i've patched and it works (at least for me). Something must have been changed in handling saving ssid/password for arduino ESP-32. regards Dirk

The speed improvement is amazing! For a webserver SD filexplorer the time for listing is currently about 2 seconds (very blocking), with this PR only 20 msecs (hundreds of mp3...

I made a speedtest example for PIO here https://github.com/tueddy/FS/tree/main/example Tested my SD-cards with a lot of files in root directory: Samsung Evo 32GB: getNextFileName(), done reading root-directory 36 elemts in...

Hi @chegewara, thank's for your fast response! I've tried to convert to SD_MMC but failed with converting functions SD.readRAW() and SD.writeRAW(). I'm using Arduino ESP32 on PIO. I've tried MSC...

As far as i can see from the benchmarks you reach 6MB/s for RAM-disk and nearly the same values for SD-card access, arround 200KB/s for write, 400-500KB/s for read? So...

Thank's for your benchmark! SD_MMC seems no rocket here, bottleneck seems to be elsewehre? How have you implemented the replacement for SD.readRAW() and SD.writeRAW()? With [sdmmc_read_sectors](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/storage/sdmmc.html) ?

For SD-card speed i can confirm the results of this [article](https://www.instructables.com/Select-SD-Interface-for-ESP32/): - SD_MMC 4 bit: 100% - SD_MMC 1 bit: -20% - SPI: -50% Best choice for minimal wiring/no pullups...

I've tested your new library and get same speed measurements for SD_MMC in 1 Bit mode. Reading spead about 800KB/s, writing 600 KB/s, thank's for improvement! I have tested on...

Perhaps this old issue will resolve itself if we ever switch to Arduino 3: https://github.com/espressif/arduino-esp32/pull/8127

Can't test it just at the moment, but can I distinguish whether in the listing is a file or directory with this commit? Made a comment [above](https://github.com/espressif/arduino-esp32/pull/7229#issuecomment-1257071883).. Thank's for your...
