In the first scenario, you have a list that is organized by aisle so you can cruise up and down each aisle only once, ending at the checkout. In the second scenario, your list is organized alphabetically, so you end up making frequent visits to the same aisles multiple times. In the end, you get all the groceries that you need, but the first scenario is clearly faster. When your hard drive's reading and writing heads move from one aisle to the adjacent aisle, they copy the data much more efficiently than if they are darting all over the disk getting the files in alphabetical order. Block-level copies tend to complete the backup in 50% to 75% of the time that an equivalent file-level backup takes. While block-level clones of an entire volume are quite a bit faster than an equivalent file-level copy, they do have some disadvantages in certain scenarios. For example, if the destination volume already has a considerable amount of data on it from a previous backup, a file-level backup will copy only the items that are different on the source and destination.
