for flash drives this is great news.. Now if ZFS would get trim support, that too would be great.
The major unknown issue with trim is how well the drives schedules/defers the trim operation so that it does not interfer with other I/Os. Also, it would be really bad if the drive applied trim after the block had been re-allocated for a write. It would also be really bad if the drive loses unrelated data if there is a power fail during trim.
If writes get blocked by a pending trim, then trim would not help very much.
