Feb 24, 2015 7:14 AM in response to Godzilaby brenden dv,Hello Godzila,
If you are looking for more information regarding Secure Erase and solid state drives, you may find the following article useful (apologies if you have already seen it):
Note: With an SSD drive, Secure Erase and Erasing Free Space are not available in Disk Utility. These options are not needed for an SSD drive because a standard erase makes it difficult to recover data from an SSD. For more security, consider turning on FileVault encryption when you start using your SSD drive.

Sincerely,

Feb 24, 2015 7:42 AM in response to brenden dvby Godzila,Thanks - interesting read that confirms my thoughts...
The finder UI definitely proposes to *secure erase" items on an SSD drive (be it Apple "blessed" or user replaced), irrespective of the TRIM support within the OS.
And it seemingly does something (at the very least the procedure takes considerably longer than a "standard" erase).
The question remains: what does that command actually do ? Is it "simply" a useless (and potentially dangerous) leftover from the early versions of MacOS X that did not have any knowledge of SSDs or is there more to the story ?
I'm surprised there is no tech note abut this subject.
