I was trying to check out what scheduler the system is using and to my surprise I get the output "none".
SSD.

It's not only SSD. Since kernel 3.13 many device drivers use multi queue block io (blk-mq) and bypass any scheduler. The file /sys/block/sd<X>/queue/scheduler is still there, but doesn't mean anything. I get "none" for my rotating rust too.
