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’
进入管理界面后 点击 创建新的 虚拟硬盘池.
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.
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.
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.
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.
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:

可以看到 读的速度明显加快了 写稍微可能会慢一些.
