do i need trim for my SSD?

[agentcooper2001]

i have a late '08 15" 2.8 macbook pro. Internal HD is a 320gb Hitachi. I'm running a Filemate 48gb expresscard SSD, which is working great so far! very fast.

what i'm wondering is, is there any need to download and enable TRIM for it? i'm running the latest version of snow leopard.

lets first determine if your SSD even supports trim.

To see if your SSD supports trim or not:
Open up System Profiler (that's —>About This Mac—>More Info); then select Serial-ATA on the left hand side, and click on your SSD in the device tree. It will be listed as such—

thanks guys....just checked and it does not support trim.

that doesn't identify whether the SSD supports TRIM, just whether OSX does.

Only the 2011 MBP 10.6.7 and the 10.7 previews support TRIM, and only for Apple drives unless you hack a driver. After that, the OS will support TRIM on any drive that natively supports it.

Good morning you guys.

If I just ordered my OWC MEP 115GB which has garbage collecting. Would I need to still enable TRIM for OSX by using this little tweak?
