I was wondering about whether using options like "autodefrag" and
"inode_cache" on SSDs.
On one hand, one always hears that defragmentation of SSD is a no-no,
does that apply to BTRFS's autodefrag?
Also, just recently, I heard something similar about "inode_cache".
On the other hand, Arch BTRFS wiki recommends to use both options on SSDs
http://wiki.archlinux.org/index.php/Btrfs#Mount_options
So to clear things up, I ask at the source where people should know best.
Does using those options on SSDs gives any benefits and causes
non-negligible increase in SSD wear?
