What is Thunderbolt 3 Port?

Thunderbolt is a popular platform that was designed to rival with a USB 3.0 port.

It can transport data at a quicker rate than USB 3.0 that can transmit data up to 5 Gbps.

In addition to serial data, it can also transfer data from a range of data storage devices.

What is Thunderbolt 3 Port?

Thunderbolt is the brand name for Intel and Apple’s hardware interface.

The Thunderbolt 3 is a version of this interface that allows users to connect a laptop to a large number of external devices.

Thunderbolt 3 differs from Thunderbolt 1 and 2 use the USB Type C port, whereas previous versions used a Mini Display Port.

When the port was first developed and promoted, the term “Light Peak” was devised.

On January 8, 2018, Intel renamed this interface Titan Ridge and modified it.

This has higher power have been able to support DisplayPort 1.4.

It has a Thunderbolt 3 port with one PCIe 3.0 4 links and two Thunderbolt 3 ports on the other PCIe 3.0 2 links.

What is Thunderbolt 3 Port

Types of Thunderbolts 3 Port offered by Intel:

  1. DP or Double Port: It has two Thunderbolt 3 ports and a PCIe 3.0 4 link.
  2. SP or Single Port: It contains a single Thunderbolt 3 port and a PCIe 3.0 4 link.
  3. LP or Low Power: Two Thunderbolt 3 ports on a PCIe 3.0 2 link.

Advantages of thunderbolt port:

1. Faster than USB:

Thunderbolt 3 offers four times the data transmission speed of a traditional USB port.

Thunderbolt 3 has a data transmission rate of 40 Gbps, USB 3.1 has a data transfer rate of 10 Gbps, and USB 3.0 has a data transfer rate of 5 Gbps.

2. Higher bandwidth:

Thunderbolt 3 provides double the bandwidth of Thunderbolt 2.

Besides attaching a graphics amplifier, you may boost your visuals and transform your laptop into a gaming machine.

The speed is the same when linked to the motherboard.

3. Connectivity options:

You will have extra connectivity with a Thunderbolt 3 port.

Your laptop can be connected to an external hard drive, several external monitors, and other devices.

You can connect a USB Type C device to this port because it uses USB Type C ports and functions identically to a USB Type C 3.1 port.

4. Better networking:

A Thunderbolt 3 port can be used to connect two devices for high-speed networking.

The data transfer rate will be five times that of a standard Ethernet port.

5. Charging:

You will have extra power to charge your device because the Thunderbolt 3 port supports the USB Power Delivery standard.

The100 watts of power can be sent and received which is more than enough to quickly charge your laptop.

6. Daisy Chain:

You may link up to six laptops and other devices using Thunderbolt 3 and the appropriate cables.

7. Three-in-one option:

Three distinct alternatives are combined into this technology.

You will have a DisplayPort and PCI Express combination in two serial data streams, and a DC connection for extra power.

8. Connect to external graphics cards:

When connected to external graphics card units with high bandwidth and low latency, this interface provides for graphics-based expansion and outstanding performance.

9. Future proof:

Thunderbolt 3 support for USB C ensures the security of your laptop, external devices, and accessories in the future.

Simultaneously, it will standardize the production of glasses across the board.

10. Ergonomics:

The Thunderbolt 3 appears to be had good ergonomics and is substantially smaller than prior generations.

It also includes a reversible cable and is more convenient to use because it works in any direction.

11. Flexible:

Thunderbolt 3 is more flexible so it offers many new and interesting possibilities.

Disadvantages of thunderbolt port:

1. Option ROM attacks:

When Thunderbolt boots, this capability is vulnerable to ROM attacks that are loaded and performed.

These are harmful and they can potentially attack your machine before it even starts up.

These encryption keys can be used to capture log keystrokes and kernels, increasing vulnerability to attack.

It may also impact the system’s boot software by overwriting the SPI Flash ROM.

2. Data exposure:

The Thunderbolt protocol has been revealed to have major security vulnerabilities.

Whether the system is a password-protected, encrypted hard drive, or is locked, it permits malicious parties to access the data stored on the laptop.

And even worse, there is no way to fix it with a software update.

3. Expensive:

When it comes to price, it will certainly be more expensive, costing ten times like other standard FireWire and USB interfaces because of the use of Intel and Apple-owned technology.

4. Compatibility issues:

When compared to USB, Thunderbolt 3 has a smaller number of compatible devices and peripherals.

As a result, if you want to employ this technology, you will have to spend more money on new equipment.

This means you will have to replace older equipment to make use of the new technology.

5. Daisy-chaining option:

When it comes to daisy-chaining several devices, a Thunderbolt 3 port can only handle six devices.

In comparison, a USB port can accommodate up to 127 devices, while Firewire allows up to 63 devices to be daisy-chained.

6. Confusion with USB:

Since the Thunderbolt 3 cable resembles a USB Type C cable, you can assume that Thunderbolt 3 will be supported by all USB Type C ports or that the cables will be convertible.

This will confuse you, and you may ultimately pick the wrong choice, leading to a lack of speed or functionality.

7. Size matters:

The Thunderbolt 3 interface has a limited ecology that will limit the environment of existing devices.

As a result, it may not be suitable for usage by average consumers.

8. DMA attacks:

Due to data transport and connectivity security problems, the Thunderbolt 3 interface is vulnerable to Direct Memory Access (DMA) attacks.

This can infect your system with many varieties of malware.
