We can tell that Thunderbolt still being the fastest when compared with the USB 3.0 5Gbps (Giga bits per second), eSATA 3Gbps. FireWire 800 Mbps and USB 2.0 480 Mbps (Mega bits per second). Intel stated that with this rate of data transfer speeds, the Thunderbolt technology capable of transfering a full-length HD movies less than 30 seconds.
Intel said that there are two protocols that work together on Thunderbolt technology, PCI Express (PCIe) and DisplayPort. Beside that Thunderbolt supports full duplex, so it can receive and send data simultaneously at 10Gbps speeds.
Thunderbolt is based on Apple DisplayPort technology, so you can still use the Mini DisplayPort. You can also use standard adapters for DVI, HDMI, and VGA. But however the Thunderbolt technology compatibility on hard drives and audio devices is still in question. Right now the devices that use Thunderbolt technology currently on the market is just for display device only.
Beside the compatibility issues, another thing to be concerned is that the Thunderbolt is product of Intel technology. This means you will not be able to find Thunderbolt ports on computers that use AMD chips or other CPU brands.
Thunderbolt features :
- Simultaneous bi-directional, 10 Gbps
- transfers over a single cableDual-protocol support (PCI Express* and DisplayPort*)
- Compatible with existing DisplayPort* devices
- Daisy-chaining devices
- Choice of electrical or optical cables
- Low latency with highly accurate time synchronization for professional audio and video applications
- Uses native protocol software drivers
- Power-over-cable for bus-powered devices
