That is done while simultaneously archiving the data stream and rendering, transcoding, and moving content in the background--all without bringing your machine to a grinding halt. Now, the extra RAM, disk speed, and powerful graphics card add a noticeable speed boost to your machine.

With that power, tasks like ingesting media become a minor background chore rather than a consuming process. You can immediately start editing in the foreground while the file is being transferred or transcoded for proxy creation, all of which happens in the background.

There's a noticeable improvement in media handling and responsiveness after the transfer/ingest is complete. This is due to additional processing power being allocated back to application as soon as the Finder has completed its tasks.

Final Cut Pro X never lagged, even as I pushed the machine to the limit, often while rendering high-resolution output as DPX frames and simultaneously transferring media to multiple external drives--in addition to rendering files for playback on my iPad and prepping content to be edited on a MacBook Pro.

This is genuine multitasking and it feels good.
