Hi,
Well if you don't trust magician then samsung ssd's shouldn't be used :)
The firmware does the trim operation which ultimately marks deleted blocks as writable thus your inquiry
I suppose you can do it the old fashion way or the way Crucial ssd support posted to me a while back
Enter your bios and let the machine sit over night.
The ssd has power but no activity this is when the firmware is supposed to do it's trim operation.
