并行传输数据和串行传输数据

SATA hard drive connections are faster than older PATA hard drive connections and the same can be said for external cabling standards, but this is counter-intuitive: why wouldn’t the parallel transmission be faster?
SATA硬盘驱动器的连接速度比旧的PATA硬盘驱动器连接要快,对于外部电缆连接标准也可以这么说,但这是违反直觉的:为什么并行传输不会更快?

问题 (The Question)
SuperUser reader Modest is curious about the data transfer rates of parallel and serial connections:
SuperUser阅读器Modest对并行和串行连接的数据传输速率感到好奇:
Intuitively, you would think that parallel data transmission should be faster than serial data transmission; in parallel you are transferring many bits at the same time, whereas in serial you are doing one bit at a time.
凭直觉,您会认为并行数据传输应该比串行数据传输快; 并行操作是同时传输许多位,而串行操作是一次传输一位。
So what makes SATA interf
