AFAIK, ethOS comes as a disk image, so you should be able to write it to your SSD... Untested by me tough, just based on what i've read about this OS in the past
okey but i have read that running a Os from usb will like destroy your usb after a while of running it.

You were talking about running the OS from your SSD, not an USB... And even then, you can always put the image on a new usbstick anyways, it's not like the stick will store your actual wallet, so if it is fried, nothing is lost but one or two hours of your time (offcourse, you shouldn't put important data on the same stick you run your mining os from)...
