danudey left a helpful link to a comment I made recently about TRIM support in Lion. Apparently, 10.6 is doing some good SSD maintenance even without TRIM support, and SSDs do not experience the same performance drops as they would on a Windows machine without TRIM support, but it is not clear why this is the case.

- r00fus 16y agoDoes that apply to all SSDs? From what I gather TRIM is just a spec for formalized OS-level garbage collection hooks. Some disks (like Apple-installed Samsungs) do GC at the disk-level. My Sandforce (Vertex 2) has disk-level GC (as well as TRIM), and sometimes will block for a long period on writes now on OSX... I haven't tried it on a different OS yet.
