Subject: which IO-scheduler is best for flash based storage device with ext4

Hi,

Could you tell me which  IO-scheduler is best for flash based storage device with ext4 ?
Just search from WWW, I saw it is said that the noop is best because the CFQ is design for the mechanical hard disk.
And I did the performance test with IOzone between the IO-scheduler noop and cfq. The performance difference is small.
So here I want to get some answer from you about this question.

Thanks.
Huang weller
