去年年初，为了体验4k的“塞尔达传说-旷野之息”，我升级了我的电脑，并在18年不断完善，目前经过optane加速的4T硬盘，速度提升非常显著，很是喜欢。但电脑里有些录音，以及家庭照片，想随时观看，而不想开电脑，另外也起到备份的作用（数据无价），所以一直在考虑采购一台NAS，但感觉现在的NAS及配件（硬盘）功能比较弱（其实就是没米。。。），所以就考虑利用现有资源，把1T的闲置移动硬盘挂载到 WRT1200路由器下，这样 Win/Mac/手机 通过sshfs/samba远程挂载目录，这样可以体验简易NAS，等时机成熟了再考虑NAS，此篇主要总结如何挂载移动硬盘，由于环境版本的不同，总结中的内容可能跟读者遇到的会有少许差异，如遇到问题，可自行google或baidu

有时候通过LEDE的luci直接挂载不起作用，也弄不明白为啥，所以还是CLI最靠谱。另外在openwrt里，移动硬盘的格式最好是ext3或ext4，这样效果高，问题少。另外就是最开始我想用sshfs，但后来发现windows访问sshfs效果非常不好，所以对于windows，就换回了samba服务器，速度不错，可以达到平均60MB/s 上下

另外Samba配置，可以参考我之前的文章 Deploy Samba on OpenWRT

1. 国内更新源，这样就可以随便更新软件了
