Yosemite SSD Trim Workaround ?

[daveg999]

Ok - so you can't get Yosemite to automatically recognise the 3rd part drive. What would be the situation regarding periodic maintenance if you created a OS X Bootable USB for either Yosemite or a previous OS X version which had TRIM enabled. Could you not boot of that say once a month and leave it to tidy up the SSD ?

Not tried it - frankly not sure how to prove it was working. Just an idea.

If the concept works someone should try and create a boot image for a TRIM enabled OS X.

TRIM won't work over USB, but if you use Thunderbolt or eSATA for an external, or even another internal drive.... yes you could do that.

Just boot from the external drive then mount the Yosemite drive and run the command fsck -fy from single user mode and that would TRIM all unused blocks on the drive.
