SATA (Serial AT Attachment) [a][2] is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives. Serial ATA succeeded the earlier Parallel ATA (PATA) standard to become the predominant interface for storage devices.

2024年11月22日 · SATA的速率协商过程使得主机和设备能够在兼容的最大速率下进行通信。 SATA目前支持三种数据传输速率：1.5 Gbps（SATA I）、3.0 Gbps（SATA II）和6.0 Gbps（SATA III）。 Power On（上电）的最后就是Host和Device在进行速度协商。 协商的过程如下

2023年3月21日 · SATA is a computer bus interface that helps connect the storage disks like Hard Disk Drives (HDDs) and Solid-state Drives (SSDs) to the motherboard. Unlike its predecessor PATA, the SATA interface supports a much higher data transmission rate, and its ports, cables, and connectors are not as bulky.

2024年2月16日 · The SATA port is used for connecting storage components (SSDs, etc.) to your computer’s motherboard. SATA uses two ports: The data connector and the power connector.

SATA ports are found on a computer's motherboard and are used to connect internal devices like hard drives, solid-state drives, and optical drives. SATA drives need two separate cables to function - one is the SATA data cable and the other is the SATA power connector.

2023年10月11日 · In this article, we’ll explore the three main types of SATA ports commonly found on motherboards: SATA 1.5 Gbps, SATA 3 Gbps, and SATA 6 Gbps. We’ll discuss the differences between them, highlight their advantages and limitations, and ultimately help you determine which SATA port is the best choice for your SSD.

2023年3月20日 · SATA ports are small connectors that allow you to connect storage devices to your computer. These ports come in different shapes and sizes, depending on the type of device they’re designed to connect. For example, you might have a 7-pin SATA port for connecting a hard drive or a smaller 6-pin port for connecting an SSD. But that’s not all!

SATA PM 需要得到基于命令或基于 IFS（帧信息结构）交换的控制器支持才能实现端口复用功能。 这两种方式可分别提供适用于不同特定环境的独特功能。

2022年3月19日 · 本文介绍了SATA的Port Multiplier（PM）技术，包括PM的切换类型，如Command-Base Switching和FIS-Base Switching，以及PM在传输和冲突处理中的角色。 在冲突处理部分，详细阐述了如何处理设备与主机同时发送数据导致的冲突问题，确保数据传输的正确性。

2024年11月27日 · PCIE Root Ports扮演的是一个P2P bridge的角色，Root Ports自身产生的Intterupts的处理方式和Internal Devices处理方式一样；Root Ports所接入的设备所产生的Intterupts，则会有Root Ports转发给上一级的Root Complex去处理。
