If you can preserve and scan the tissue in a way that lets you scan the same area multiple times you wouldn't need to digitize the whole thing. Put the slices on rotating platters with a microscope for each platter and read parts of the brain on demand. It's a hard drive but instead of magnets storing the bits of an image of the sample, it's the actual physical sample.

Not if you want to actually execute the state of a human brain in a digital simulation to see how it works and whether it still displays certain abilities such as comprehension and consciousness. Otherwise a digital scan of a brain is just a glorified microscope.
