OpenZFS on OS X

In the tutorial it states using ashift=13 if any pool devices will be ssd.

Does this count for l2arc / zil?

Currently have 4 non-ssd disks set to ashift=12, looking to add l2arc and zip and wondering if I have to change this.

The advice to use ashift=13 for SSDs is a little contentious. Its quite space inefficient. ymmv.

l2arc/slog are not subject to this i.e. you cant control the ashift for cache devices.
