proper newfs options for SSD disk

[User Wojtek]

what are proper settings

a) 4kB fragments so everything is 4k aligned? SSD drives itself reports 
as 512 byte blocks, but it is recomenned constantly on many places about 
4K alignment for SSD.

b) small fragments (like 1KB) to reduce space usage, as there is no 
seeking so it will not slow down but save space on relatively small SSD

c) anything else?


i use b) now.
