4.1 Central Processing Unit (CPU) Architecture (1 questions)
The most suitable port for connecting a high-speed external SSD would be a USB 3.0 or USB-C port.
Justification: SSDs require high data transfer speeds to realize their full potential. USB 3.0 and USB-C offer significantly faster data transfer rates compared to older USB standards (like USB 2.0). USB-C is particularly advantageous because it supports the USB 3.1 Gen 2 and USB 3.2 specifications, which provide even higher speeds. Modern SSDs often require a reasonable amount of power to operate, and USB ports, especially USB-C, can provide this power. Compatibility is also a key factor; most modern computers have USB 3.0 or USB-C ports, making it a widely compatible solution.
Evolution of Port Technology:
| Technology | Speed (approximate) |
| USB 1.0 | 1.5 Mbps |
| USB 2.0 | 480 Mbps |
| USB 3.0 (USB 3.1 Gen 1) | 5 Gbps |
| USB 3.1 Gen 2 | 10 Gbps |
| USB 3.2 | 20 Gbps |
| USB4 | 40 Gbps |
Each generation of USB has significantly increased the data transfer speed, allowing for faster data access and improved performance for devices like external SSDs.
