Flash scheduling algorithms?

I am trying to do some research around file systems and I have probably confused myself. I have disk scheduling algorithms for devices with disks like SCAN and CSCAN, but I was wondering what the equivalents for flash are?

There are some approaches to research, such as in the 2009 paper A New I / O Scheduler for Solid State Devices . However, I do not know that this is used in practice. The "Noop" scheduler, which means the scheduler does not reorder requests, seems to be the standard scheduler for use on SSDs.



Either way, a lot more needs to change in today's OS to really work with today's and future SSDs, as stated in this MSST 2010 paper .
