Are there any real advantages of ext4 over ext2 ?

[Manish Jain]

Hi,

I have a dual boot computer with FreeBSD and Linux.

My Linux partitions are ext4 simply because ext4 is now the default 
under Linux. However, ext4 is not supported directly by FreeBSD. As a 
result, writing to those filesystems from FreeBSD is painfully slow (via 
fuse).

It is notable that ext2fs is directly supported by FreeBSD.

ext4 supports huge files (in terra bytes) and filesystems (in thousands 
of peta bytes). But very few people have such files/filesystems. At 
least, don't - my use case is max 64 GB file, max 500 GB filesystem.

So I wonder are there any real advantages of ext4 over ext2 ?


Thanks for any inputs,
