This example demonstrates a benchmark of a storage media such as SPI flash memory and SD card. This example demonstrates a benchmark of a storage media such as SPI flash memory and SD card.
Only ESP32 and ESP32-S3 targets can use SDMMC mode when connecting to a SD card. Only ESP32 and ESP32-S3 targets can use SDMMC mode when connecting to a SD card.
This example provides comparison between different types of storage in terms of speed under various configurable (from menuconfig) conditions
Currently these mediums and file-systems are supported:
- SPI Flash
- Raw access
- FATFS
- SPIFFS
- LittleFS
- SDMMC/SDSPI card
- Raw access
- FATFS
- LittleFS
### Comparison scheme
For each filesystem, four sets of benchmarks are run:
- Target size R/W
- More than target size R/W (about target_size x 1.2)
- Less than target size R/W (about target_size / 1.2)
- Tiny size (255 bytes)
Some filesystems are also tested in two modes:
- New file - new file gets created every time
- Normal - the old file gets overwritten each time (`O_TRUNC`)
Every benchmark (except SPIFFS ones) is run multiple times (can be configuredd) for better accuracy, as the results often vary between runs.
We recommend using at least `100` runs, but default is set to `10` for convenience.
### Disclaimer
While this benchmark tries to give objective results, they may vary by significant amount with different settings, especially for filesystem with large amount of compile time configuration options such as LittleFS.

### Note about SPIFFS
The test for SPIFFS is run only once, because SPIFFS has a problem with deleting files.

#### Note about LittleFS
LittleFS offers many other compile time configuration options which need to be set in it's component config.
These setting will have effect on it's performance.
#### Note about FATFS
To achieve the best performance the cluster should match with the target size, and be as high as possible.
However the higher the cluster size the more space will be wasted by partially filled clusters.
Keep in mind that the cluster size needs to be a multiple of sector size for SPI-flash that's 4096 and for SD-Card it's 512.
Also, the size of the storage medium determines maximum cluster size, for that reason this example uses 2MB of flash just for the filesystem (4MB by default, for smaller cluster sizes (16k) around 1MB should be enough.

help
This is the target size used for the benchmark,
it represents how much data will be transferred in each test.
(The actual size of the allocated buffer will be larger for "more than target size" cases.)
The test will test will show the performance of reading and writing
of both slightly more and slightly less than this size as well.
This will greatly affect the performance of the benchmark.
In general, the larger the rw size, the better the performance.
For FATFS, the best performance is achieved when the rw size
matches the cluster size or is at least a multiple of the sector size.
