Very interesting. Do you notice any slow down over time? I think I'm right in saying that OSX doesn't implement the trim command or something like that?
This is correct (no support for TRIM), but the performance degradation is not very significant. I'm certain I've used all blocks on my SSD and it's still way faster than HD for random access. Sequential write is noticably slower, but that doesn't happen often -- copying a large backup, etc, but then I can do something else or get a drink while waiting. Random = interactive = fast.
Intel's SSDs don't perform worse if you don't use TRIM. They pre-erase and move blocks of data around in background so that when you go to write there is always some space to do so.
The downside is that sequential writes are bandwidth-limited compared to other SSDs, but this doesn't matter in practice with small random writes completing very quickly.
