Hi HenryMoray,
Thank you for reaching out Microsoft Community.
The SSD card of the Surface Go is not removeable. If you'll forcibly remove this from the Surface Go, it may induce damage to other hardware components of the unit. It will nullify the warranty of the Surface device and may hinder the user from getting a replacement if in case he/she decides to send it for service.
Hope this answers your question.
Kind Regards,
Crest
