I’d erase it in Disk Utility then use Carbon Copy Cloner to clone to the erased drive. As it’s an SSD you can erase it as APFS, High Sierra will boot fine.

I have a 450GB SSD which I’d like to use externally as the main drive. I thought I had cracked it but the smaller SSD (than the internal HD) was a problem even though I am only using 50% of the internal HD space so SSD easily big enough. Disk Utility restore doesn’t seem to work (I get an error message) so I’m a bit stuck. Any ideas gratefully accepted…..
