Hi I' ve installed a Samsung 830 256 Gb SSD in my Early 2011 17" MBP. In Lion all works really well, super fast UI, super fast app launch ecc. In ML (installed as updatem not clean install) I' ve some problem with a considerable performance drop (with TRIM active). So I decided to try a ML clean install but first I need to "format" my SSD. My question is: which is the best wat to format a SSD to came back to the new state? I only need a quick format or a secure erase? Thanks!!
