用 Win 10 的 Storage Space 创建 软件 RAID

有一个1.5TB 和一个1TB 的硬盘是从老PC上拆下来, 扔了可惜. 这两个硬盘都是 Seagate, 7200转, 64M缓存, 质量还不错. 碰巧 HPZ800的主机里支持接 4个 SATA接口的硬盘

打算把这两个硬盘来存些电影家里 2TB的 NAS快被各种片塞满了 (包括A片). 但是又不想直接有两个硬盘 (有点小强迫). 想把所有的都放在一起. 刚好 WIN 10的这个 Storage Space 创建虚拟大硬盘这个功能可以满足我. 最主要是以后虚拟大硬盘空间用完了还可以动态添加.

在开始菜单处搜索 ‘Storage Space’

storage-space

进入管理界面后点击创建新的虚拟硬盘池.

manage-storage-spaces

选择未被使用(格式化的硬盘) 当然也可以选择已经格式化的硬盘只不过所有选择用来创建硬盘池的硬盘都将会被格式化重新使用.

select-drives

系统准备…

选择 Simple-No-Resiliency 类似 RAID 0 这种方式将不会有数据冗余. 也就是说如果一个硬盘坏了数据将丢失. 当然由于数据会被较为均匀的分布在两个不同的物理硬盘上所以读写速度会稍稍快一些.

simple-no-resiliency

Two-way-mirror 这种方式类似 RAID 1 也就是完全镜像. 需要至少两个硬盘. 数据将会有一份完全的备份. 读写速度会慢一些. 适合存储重要的数据.

two-way-mirror

当然还有其它的配置. 我这里就选第一种. 也不是什么重要数据当然我也信任这硬盘的质量.

summary

最后我得到了一个虚拟 2.3TB 左右的大硬盘. 之后不够还可以添加硬盘. Share on X

性能测试

HPZ800主板SATA接口只支持 SATA II 也就是 3GBps (不管你用的是不是SATA3). C盘是主硬盘也是SEAGATE. 所有三个硬盘都是 7200转, 64M 缓存所以如果单个测试的话应该都差不多.

用管理员运行命令 winsat disk -drive c 得到主硬盘:

用管理员运行命令 winsat disk -drive d 得到虚拟硬盘的性能:

可以看到读的速度明显加快了写稍微可能会慢一些.
