Hi all,

I've got an Intel 335 SSD with Yosemite and Windows 8.1 installed.

I've tried to enable TRIM, and trashed Yosemite a few times, now realising you need to disable kext signing, which isn't really something I want to do.

When booted into Windows 8.1, there's an Intel SSD Tool, which can 'optimise' the drive, which basically forces a TRIM command to run.

My question is, when forcing TRIM to run from Windows, does that TRIM the entire drive, or only the Windows partition? Obviously the Windows partition only has read access to the Yosemite partition, so I wasn't sure if this would prevent it working, or if the TRIM command worked at the block level across the entire drive, independant of the OS.
 
TRIM is based on the OS and since you're running Windows, it will only operate on your windows volume. You'll need to enable TRIM on OS X as well, so your HFS+ volume can benefit.
