SuperSpeed USB 3.0 has a maximum throughput of 5 Gbps, which makes Thunderbolt 2 up to four times as fast as USB 3.0. Recently, the USB Promoters Association announced the USB 3.1 spec, which...
However, optical Thunderbolt 1 and 2 cables could be used at the time with Apple's Thunderbolt 3 (USB-C) to Thunderbolt 2 adapters on each end of the cable. This achieves connections up to the 60 m (200 ft) maximum offered by previous versions of the standard.
Thunderbolt is a data transfer standard that mixes video streams conforming to the DisplayPort standard with data from the computer’s PCI-e bus. That’s a fancy way of saying it’s a single port that does everything, and you can connect anything from hard drives to 4K monitors to it.
Thunderbolt 2 vs USB 3.0 vs eSATA: Speed. All three standards are much, much faster than USB 2.0, which tops out at 480Mbps. eSATA can deliver 6Gbps (older versions deliver 1.5Gbps or 3Gbps), USB...
Thunderbolt 3 and Thunderbolt 4, for example, reach speeds up to 40 Gbps, while the new Thunderbolt 5 standard reaches a ludicrous 80 Gbps (or up to 120 Gbps when used for unidirectional ...
While Thunderbolt 1 has 4 channels, Thunderbolt 2 combines two channels so overall it has two channels, each of 20Gbps. Thus with the same bandwidth as Thunderbolt 1, Thunderbolt 2 causes less overhead and enables more efficient transfers.
The fastest Thunderbolt external hard drives will deliver read speeds of around 2800MB/s and 2400MB/s write speed such as those achieved by the SanDisk Professional Pro. Since around 2017, all new Macs have a Thunderbolt 3 port and the latest Macs have Thunderbolt 4 ports.
