mke2fs -j -m 0 -N $NUMBER /dev/whatever
(or)
mke2fs -j -m 0 -T largefile4 /dev/whatever

Don't change this. It'll get set at 4096.

> -i bytes-per-inode
> -T fs-type

If you want to specify the number of inodes, use -N $NUMBER, which will
create $NUMBER inodes Don't create less than 1000; it's really annoying
to run out of inodes. -T largefile4 will, like it says in the man page,
create 1 inode for every 4M. This should be plenty. The biggest win
here actually comes from -m0 , which should work because this is not /var
or / , so your system won't get b0rken if you fill up the partition.

I have a 110GB partition that I want to use to record large movie files.
Most files would be minimum 0.5GB and go to 3-7GB. What settings should
I use to format the partition for optimal performance and minimization
of wasted space? I want to use EXT3.

Is there a guide or howto on this? Anyone have any experience with this?
I've read the mke2fs man pages, but they don't specifically explain what
settings you would use under which conditions.

Which options would help?
-b block-size
-i bytes-per-inode
-T fs-type
