Introduction to USB technology

When I’m weighing up the choice between " DEKO USB-C Cable USB 3.2 (100W, 20 Gbps)" and "DEKO USB-C Cable USB 4 (240W, 40 Gbps)", it’s important to understand USB technology. The USB (Universal Serial Bus) standard was introduced in the 1990s to simplify connecting different devices.

Key USB Versions

USB 2.0: Speed up to 480 Mbps; power up to 15W.
USB 3.2: Speed up to 20 Gbps; power up to 100W.
USB 4: Speed up to 40 Gbps; power up to 240W.

Key differences between USB 2.0 and USB 3.2

When I compare USB 2.0 with USB 3.2, the differences are significant. Here are the key aspects:

Data transfer speed:
- USB 2.0: maximum speed up to 480 Mbps.
- USB 3.2: maximum speed up to 20 Gbps, which is significantly faster.
Device compatibility:
- USB 2.0: widely used, but slower.
- USB 3.2: backward compatible with USB 2.0 devices, but offers better performance on newer hardware.
Power:
- USB 2.0: maximum power 2.5 W.
- USB 3.2: can deliver more power, which is ideal for newer devices that require higher wattage.

By using modern cables such as "DEKO USB‑C USB 3.2 cable 100W 20Gbps", I can notice significant differences in speed and performance.

Data transfer speed

USB 2.0:
The maximum speed is 480 Mb/s (megabits per second), which translates to 60 MB/s (megabytes per second). In practice, transfer speeds are often lower, typically between 20 MB/s and 40 MB/s, depending on file types and other factors.

USB 3.2 Gen 2x2:
The maximum speed is 20 Gbps (gigabits per second), which corresponds to 2.5 GB/s (gigabytes per second). In practice, the actual speed may be around 2 GB/s.

When I choose a cable, data transfer speed is one of the most important factors. Cables such as Deko USB-C USB 4 cable 240W 40 Gbps offer speeds of up to 40 Gbps, which is incomparably higher than older standards.

Cable	Transfer Speed	Power
Deko USB-C to USB Cable USB 3.2 100W 20 Gbps	20 Gbps	100W
Deko USB‑C to USB‑A USB 2.0 Cable 15W 480 Mbps	480 Mbps	15W

Such differences can make a huge impact:

Transferring large files: 4K movies, backups.
Games: Minimizing latency.
Office work: Using docking stations like Deko Hub Business USB‑C 8‑in‑1 docking station.

With the way technology is heading, 2024 will bring even faster transfer speeds for USB‑C, which will make choosing the right cable crucial for optimal performance.

Practical difference in data transfer:

To illustrate the speed difference, let’s compare transfer times for different file sizes:

A 1 GB file:
USB 2.0:
Transferring this file will take about 25–50 seconds (at a real speed of 20–40 MB/s).

USB 3.2 Gen 2x2:
Transferring the same file will take about 0.5 seconds (at an actual speed of 2 GB/s).

10 GB file:

USB 2.0:
The transfer will take between 4 and 8 minutes (at a speed of 20–40 MB/s).

USB 3.2 Gen 2x2:
Transferring a 10 GB file will take about 5 seconds.

A 100 GB file:

USB 2.0:
The transfer will take from 40 minutes to over an hour (at 20–40 MB/s).
USB 3.2 Gen 2x2:
Transferring a 100 GB file will take about 50 seconds.

USB 2.0 applications

When thinking about a “DEKO USB-C USB-A USB Cable 2.0 (15W, 480 Mbps)", the first thing that comes to mind is the versatile use of the USB 2.0 interface.
