Hi, there is a native queuing at my INTEL SSD 64GB, so i'v set "noop" scheduler via udev rules. And it's kind a luggish when deleting a lot files like kernel sources (at ext4,xfs,btrfs, FS makes no difference, some cheap hardware stuff). Will test some day another scheduler like "deadline" on top of native one at hardware, it's some kernel overhead but hope system will not freeze for half a minute or more at high I/O....
For me best performance was at XFS, but for you ZFS (or less stable BTRFS) may be a better choice if you have powerful enough CPU, my 2 core + HT Intel Atom is too slow for it =( and fstab options for my XFS (discard = trim option) attr2,discard,inode64,noquota,relatime And the best guide is at Arch wiki=) As always=) https://wiki.archlinux.org/index.php/Solid_State_Drives
