Is there any recommendations available to get max from SSD disk using? for application server
SLES11 SP3 /ext4 file systems. Any best practices ?

Which one will be better for ext3 /ext4 application mount point:

noatime,nodiratime,nobh,data=writeback, Then set kernel to NOOP. (Restart)
echo noop > /sys/block/sdb/queue/scheduler

or


noatime,nodiratime,discard,errors=remount-ro 0 1
echo noop > /sys/block/sdb/queue/scheduler

or


ext4 defaults,errors=remount-ro,noatime,discard 0 1
echo noop > /sys/block/sdb/queue/scheduler

or


ext4 noatime,data=writeback,barrier=0,nobh,errors=remou nt-ro 1 1
echo noop > /sys/block/sdb/queue/scheduler
