在 Linux 上检测 IDE/SATA SSD 硬盘的传输速度
检测 Linux 上 IDE/SATA SSD 硬盘的传输速度
在 Linux 环境下,我们可以通过 hdparm 和 dd 命令来评估硬盘性能。hdparm 是一个强大的工具,提供了对各种硬盘的外设gps ios源码 ioctls 的命令行接口,这些接口由 Linux 系统的 ATA/IDE/SATA 设备驱动程序子系统所支持。确保使用最新的内核版本,并且推荐使用最新内核源代码的包含头文件来编译 hdparm。
使用 `hdparm` 命令检测硬盘速度的步骤如下:
以 root 权限登录,运行以下命令:
或者
为了获取更准确的数据,重复此操作 2-3 次。这个操作测量了系统处理器、怎样创建直播源码高速缓存和存储器的吞吐量指标。例如:
要确定 SATA 硬盘的连接速度,请执行:
输出将显示硬盘的速度,即 1.5Gb/s、3.0Gb/s 或 6.0Gb/s。微星胜博源码请确保 BIOS/主板支持 SATA-II/III。
使用 `dd` 命令同样可以获取速度信息:
通过调整 `dd` 命令参数,可以进行更详细的性能测试。
除了命令行工具外,您还可以使用“磁盘实用程序”GUI 工具。小说源码分享软件在最新版本的 Gnome 中,该工具简称为“磁盘”。要测试硬盘性能,请按照相应的指南进行操作。
为了安全地测试硬盘性能,max17201源码选择只读模式。此模式下不会损坏数据。若要测试读写性能并可能导致数据丢失,请确保谨慎操作。
