This omits the idea that it's explicitly the external storage, but I've yet to think of a concise way to describe it. Calling it "'poki sin" as in the other translation implies it's actually new, but it isn't new. Saying it's "external" doesn't really work, because the spatially descriptive words in Toki Pona don't quite work that way. Describing an SD card knowing that you're talking about an SD card would be easy, but just reading text would make it hard!
