I'm away from my systems today, but is there an easy way to tweak wiper.sh or hdparm to cause only a single range per trim command. I'm curious if for the Sandforce that would still be in the 90 second range, or closer to 64x that.
Good question. The Indilinx based drives would be in the 64x range, no doubt there. But I don't know about the Sandforce. And I don't think I'm willing to inflict so many life-shortening erase cycles onto it just to find out. One thing to note: the execution time for TRIM does vary depending upon whether the (logical) LBAs are already mostly in a "trimmed" state or not. So anyone aspiring to benchmark this stuff will need to keep that in mind. My timings above were for "already trimmed" cases. I would expect them to be much slower (2x - 3x) if the sectors all held data prior to trim.
