We recently blogged, after purchasing two OCZ Vertex SATA3 Drives (240GB) and inserting them with an Optibay setting (2 Drives in one MacBook Pro; see our previous post: 2011 Macbook Pro and SATA III 6Gbps, Optibay: two HD drives – setup explained).
Since we still were experiencing freezes and Sandballs on our Mac OSX Lion 10.7 SSD Setup that were actually not related to TRIM, also the system did not feel as snappy anymore.
Conclusion: don’t use TRIM on OSX Lion 10.7, if you are using a Sandforce based SSD. Revert to the original driver and not only the Beachballs will go away, but also the system feels snappy again. See the below Benchmarks for real-life results (since AJA System Test does not work on internal drives, we can recommend using XBENCH to verify the figures for you).

UPDATE: Grant Pannell (digitaldj.net) reports on how to restore to the original settings.
