De eerste generatie Thunderboltkabels is nog opgetrokken uit koperdraadjes. Later kan dat nog verhoogd worden tot maximaal 100 Gbps als men de overstap maakt naar kabels uit glasvezel. USB 3.0 has the advantage of being faster than both, even while supplying power.ĭe technologie belooft in haar eerste vorm snelheden tot 10 Gbps in beide richtingen. USB 3.0 also provides another advantage while eSATA is faster than FireWire 800, unlike FireWire it cannot supply power. This makes USB 3.0 faster than eSATA and about six times faster than FireWire 800 (full duplex at 800Mbps). eSATA, an external connection that runs at the same speed as the internal SATA 1.0 bus, has a maximum theoretical of 3Gbps. Put side by side with eSATA and FireWire 800, USB 3.0 is far superior.

USB 3.0 is also full duplex, meaning it can upload and download simultaneously (it's bi-directional) USB 2.0 is only half duplex. USB 3.0 promises a theoretical maximum rate of 5Gbps, meaning it's 10 times faster than USB 2.0. USB 3.0 In November 2007, the USB Implementers forum announced the USB 3.0 specifications, and Intel officially demonstrated the technology at CES 2009. USB 3.0's 5.0Gbit/S and Firewire's future 6.4Gbit/S will be faster than eSATA I, but the eSATA version of SATA III will operate at 6.0Gbit/S, thereby operating at negligible differences of each other. Finally, some low-level drive features, such as S.M.A.R.T., may not operate through USB or FireWire bridging. Some single disks can transfer 131 MB/s during real use, more than twice the maximum transfer rate of USB 2.0 or FireWire 400 (IEEE 1394a) and well in excess of the maximum transfer rate of FireWire 800, though the S3200 FireWire 1394b spec reaches ~400 MB/s (3.2 Gbit/s). Most external hard-disk-drive cases with FireWire or USB interfaces use either PATA or SATA drives and "bridges" to translate between the drives' interfaces and the enclosures' external ports, and this bridging incurs some inefficiency. Some smaller devices like cameras and USB audio adapters feature a smaller version of the Type B jack, known as mini (Type B) See above These devices typically include a Type A-to-mini-USB (Type B) cable.ĮSATA Aimed at the consumer market, eSATA enters an external storage market already served by the USB and FireWire interfaces.
The USB Type B connector plugs into a peripheral device (such as a monitor or printer). The USB Type A connector plugs into the USB port on your computer. USB 2.0 is useful for adding external hard drives etc. USB 2.0 devices also work with older USB ports, again at the lower speed. Older USB devices work with USB 2.0 ports, but at 12 Mbps. In 2003, USB 2.0 connectors were introduced on computers. Since USB-compliant devices can draw power from a USB port only a few power drawing devices can connect at the same time without the computer system complaining. It can transfer data to a speed of 12 megabits per second, but those 127 devices have to share that speed. If you use a USB hub, (example: 4 port hub), you can connect as many as 127 devices to a USB port. Another view of a USB port can be seen here. Sometimes there are USB ports built into a hatch on the front of a computer. There are normally two half-inch long USB ports on the back of computers built since 1998. It's used to connect all kinds of external devices, such as external hard drives, printers, mice, scanners and more.

USB Port A universal serial bus port, introduced around 1997, is the gateway to your computer. IEEE 1394 connectors can be used to connect up to 63 external devices to a machine. Creative Labs which incorporated it into their SoundBlaster Audigy Platinium products call it SB 1394 (pictured on the right). It was also adopted as an industry standard and is called IEEE 1394 on non-Apple computers. Apple invented this technology and had branded it Firewire. Data can move across the port at up to 400 megabits per second. Usually camcorders and other video equipment use this port to get data onto a computer. Firewire - IEEE 1394 - iLINK This port is used to transfer large amounts of data very quickly.
