Which of the following copper cables provides the fastest MAXIMUM bandwidth to and from storage devices?

CAT3 (Category 3) cables are an older standard primarily used for voice communications and 10 Mbps Ethernet, offering significantly lower bandwidth.

CAT5 (Category 5) cables support speeds up to 100 Mbps Ethernet, which is slower than CAT6.

CAT5e (Category 5 enhanced) cables improve upon CAT5 to reliably support 1 Gigabit Ethernet (1GbE) over full distances, but they do not natively support 10GbE over typical lengths like CAT6.

CAT6 (Category 6) copper cables are designed to support higher bandwidths, typically up to 10 Gigabit Ethernet (10GbE) over shorter distances (up to 55 meters), and 1 Gigabit Ethernet (1GbE) over longer distances (up to 100 meters). This makes CAT6 the fastest among the options for connecting storage devices via Ethernet.
