Topic: Create new ext4 partition with Lazy Initialization

Hi.

I've read that ext4lazyinit in ext4 should improve performance of SMR harddrives.

Wouldn't it be a nice idea to include this option in the GParted GUI - as eg. a button / popup window in the "Create a new Partition" menu ?

Re: Create new ext4 partition with Lazy Initialization

I read these articles about ext4laztinit:
1. Will long time ext4lazyinit damage the drive? Why initializing inode tables in ext4 (no need any kinda init in NTFS)? etc
2. On ext4 and forcing the completion of lazy initialization

My takeaways were:
1. It is enabled by default on new enough e2fsprogs and kernel.
2. It opens scope for greater loss of data if corruption occurs and fsck is needed.
3. I didn't see how it affected performance of SMR drives one way or the other.
