If they are always under 16MB, you'll be fine, though if you could stream them out of GridFS using a chunked encoding or something like that, you might save a bit of RAM.

Writing does lock the database (or at least the shard), but if the page is in RAM, that means you're locked for the duration of a write to memory, which is inconsequential. The problem comes when you try to write to a page that's not reside
