Which of the following storage media provides the FASTEST speeds when backing up large data files?

Offsite storage refers to the physical location, not the connection type, and can be local, network, or cloud-based, so it doesn't inherently define speed.

Network attached storage (NAS) relies on network bandwidth for data transfer, which introduces latency and can be slower than direct local connections, especially for large files.

Locally attached storage, such as an external hard drive or an internal secondary drive, connects directly to the computer via high-speed interfaces like SATA or USB 3.0/Thunderbolt. This direct connection eliminates network latency and bandwidth limitations, allowing for the fastest data transfer rates when backing up large files.

Cloud-based storage involves transferring data over the internet, which is subject to internet bandwidth and provider network performance, making it generally slower than local storage for large backups.
