Markup (wrapped in a fallback tag) stored in the post_content column. When disabling the plugin, displays content in post_content column as is as HTML. If this behavior is unpleasant, check the box to "convert to HTML" when you save.

• posts - post_content column of wp_posts table.
• cache of posts - wp_postmeta table.
• meta of posts - wp_postmeta table.
• options - wp_options table.

Some Markdown plugins are store the HTML to the post_content. And store the Markdown to the post_content_filtered. This approach is superior that doesn't spew out Markdown even if you disable the plugin. But it has some problem.

• Revisions and Auto-saved posts format are HTML.
• Compare Revisions are displayed in HTML.
• Does not export post_content_filtered column.
• Bulk edit lose Markdown.

Option will be removed. Posts and cache are remains.

This is fallback tag. Markup are stored by being wrapped in a fallback tag internally. When you disable plugin, Markup displayed as HTML in a fallback tag in order to avoid the collapse of the page.
