EC200U UFS Filesystem block size?

If I were to create a 10-byte file on the UFS, how much actual flash memory space would get allocated for it?

My usage scenario: we use the EC200U to control various devices, involving both inputs and outputs. Each device comes with its own unique set of parameters. Ideally, I would like to store the parameters of each device on a separate UFS file. On a real filesystem like FAT32, ext4, ntfs, etc, there is a space penalty that comes into play if I create hundreds of files that are just 10 bytes long. The minimum amount of space allocated will be something like 1KB per file. On desktop computers, this block size is quite negligible compared to the disk size.

What is the block size on EC200U’s UFS filessytem? I need this info to figure out how best to store my application parameters as files.

Happy to answer your questions. One block size of EC200U module is 4K, please design based on this
