 <p>机械硬盘使用 SATA（Serial ATA）或 SAS（Serial Attached SCSI）接口连接，一些固态硬盘也会使用 SATA 接口。SATA 是个人计算机上最常见的硬盘连接方式，而 SAS 的接口带宽更高（虽然机械硬盘实际的传输速度通常无法跑满 SATA 的带宽），支持更多功能，并且向下兼容 SATA，因此在服务器上更常见。</p>
 <p>SATA 与 SAS 的详细对比可参考<a href="https://en.wikipedia.org/wiki/Serial_Attached_SCSI#Comparison_with_SATA">英文 Wikipedia 中 SAS 的 "Comparison with SATA" 一节</a>。</p>
+<details class="example">
+<summary>图片：SATA &amp; SAS HDD</summary>
+<p>SATA 和 SAS 接口非常相似，都使用了类似的 7 针数据接口和 15 针电源接口，难以分辨，但是两者在外观上仍存在一些细微的差别。</p>

+<p>如图所示，SATA 接口的磁盘的 7 针数据接口和 15 针电源接口之间存在一个缺口，而 SAS 接口的磁盘则没有这个缺口。这和 SAS 向下兼容 SATA 的设计一致，支持 SAS 接口的控制器或线缆可以同时连接 SATA 和 SAS 磁盘，而支持 SATA 的控制器或线缆只能连接 SATA 磁盘。</p>
+</details>
 <p>随着固态硬盘的普及，PCIe 接口的固态硬盘也越来越多见。PCIe 接口的固态硬盘通常使用 NVMe 协议，因此也被称为 NVMe SSD。NVMe SSD 常见的接口形态有 U.2、M.2 和 AIC（PCIe Add-in Card，即扩展卡）。</p>
