I don't think these are necessary. You can just call buff.buf.Reset() like you have done elsewhere. The only operation that needs a mutex is Write().

sb.mu.Lock()
defer sb.mu.Unlock()

But this is not an array, which would mean that a deep copy would need to deep copy the array too right?

Ah yes sorry, you are right. We have deepcopy.Slice() for this.
