How do I determine the block size of an ext3 partition on Linux?

The stat commands uses the physical blocksize of the hard-disk. Basically all hard-disk since their inception in 1956 have used 512 bytes blocks.

All Linux file systems have 4kb block size. Let's say I have 10mb of hard disk storage. That means I have 2560 blocks available and let's say I copied 2560 ...

On ext4, just use tune2fs to check your block size, as follows (change /dev/sda1 to your own device path):

The default block size in most Linux filesystems - 4096 bytes .

File system block sizes · 1. stat命令输出的Blocks单位通常是512bytes，也就是一个扇区。 · 2. 一个文件假设只有几个字节，其实也会占用一个文件块(Block ...

All linux blocks are currently 1024 bytes. So, again another block size when you work with vmstat. This is the block size the Linux kernel uses ... Block sizes · I/O · How to.

You can do: stat -fc %s. This will give block size of the filesystem mounted in current directory (or any other directory specified instead of the dot).

In order to provide support for a larger block size a filesystem needs to provide the correct offset-in-file to block-on-disk mapping.

For more recent systems incorporating SSDs, most recently-built SSDs work much better with 4K block sizes than with 512B block sizes, mainly ...

In General, Linux uses default block size of 4096 bytes (or 4 KB). Even if you create a file with size of just 10 bytes, it occupies 1 block aka ...
