Windows Home Server Drive Extender技术现已停产，但其概念已在名为Storage Spaces的新^{(Storage Spaces)}Windows功能中得到保留和改进。使用Storage Spaces，可以将物理磁盘分组到Pools中，然后将这些池划分为Spaces，使用常规文件系统格式化并像常规磁盘一样日常使用。这些磁盘可以通过USB、SATA或SAS连接。此功能带来了RAID的安全性并允许扩展空间来存储文件——所有这些都以较低的成本进行。

该功能提供两项基本服务：

1. 数据冗余：^{(Data redundancy:)} 确保至少有两个数据副本，每个副本位于不同的磁盘上，有助于防止在出现硬盘故障时意外丢失数据。例如，您可以将文件保存到两个或更多驱动器，这样即使驱动器出现故障，您的文件也能保持安全。
2. 单一存储池：^{(Single pool of storage: )}帮助^(Helps)您将不同的物理驱动器集中到一个逻辑驱动器中。简而言之，将物理磁盘组织成存储池，只需添加磁盘即可轻松扩展存储池，但作为单个实体处理。

^(Set)在Windows 11/10设置存储^(Storage)空间

要创建池和镜像空间，请转到“控制面板”。Press Win+X调出电源任务菜单，然后从那里选择“控制面板”。接下来^(Next)，单击“系统^(System)和安全”，然后单击“存储空间”。

当一个窗口出现时，选择“创建一个新的池和存储空间”选项。接下来，选择驱动器以创建存储池。请记住^(Remember)，如果所选驱动器包含文件，您将全部丢失并且无法从回收站^{(Recycle Bin)}中恢复它们。

接下来，选择存储空间的名称、布局和大小。

要将更多磁盘添加到当前池中，只需选择要添加的驱动器并点击“添加驱动器”选项。

不久之后，您将观察创建池的过程。如果您愿意，也可以在这里重命名池。

要创建额外的奇偶校验空间，请单击“创建短缺空间”，然后从布局选项中选择“奇偶校验”。

创建存储池时，如果容量不足，您将看到如下通知：

如果出现这种情况，请单击通知以获取一些信息并尝试修复它。

这就是您创建存储空间并开始像使用任何其他磁盘一样使用它所需要做的所有事情！

When you add new drives to an existing pool, it’s a good idea to optimize drive usage. This will move some of your data to the newly added drive to make the best use of the pool’s capacity. It’ll happen by default when you add a new drive to an upgraded pool in Windows —you’ll see a check box for Optimize to spread existing data across all drives selected when you add the drive. However, if you cleared that check box or added drives before upgrading a pool, you’ll need to manually optimize drive usage. To do so, type Storage Spaces in the search box on the taskbar, select Storage Spaces from the list of search results, and then select Optimize drive usage.

How to use Storage Spaces in Windows 11/10

Windows Home Ѕerver Drive Extender technology has now been disсontinued, but its concept has been рreserved and improved upon in the new Windows feature called Storage Spaces. With Storage Spaces, physical disks can be grouped into Pools, and these pools are then carved up into Spaces, which are formatted with a regular file-system and are used day-to-day just like regular disks. These disks can be connected either through USB, SATA, or SAS. This feature brings the safety of RAID and allows expanding space to store files – all at a lower cost.

The feature provides two basic services:

1. Data redundancy: Makes sure there are at least two copies of data, each living on a different disk, helping to prevent any accidental data loss in case there is a hard disk failure. For example, you can save files to two or more drives so that your file remains safe even if the drive fails.
2. Single pool of storage: Helps you pool different physical drives together into one logical drive. In short, organizes physical disks into storage pools, which can be easily expanded by simply adding disks but handled as a single entity.

Set up Storage Spaces in Windows 11/10

To create a pool and a mirrored space, go to the ‘Control Panel’. Press Win+X to bring up the power task menu and from there, choose ‘Control Panel’. Next, click ‘System and Security’, and then ‘Storage Spaces’.

When a window shows up, select the ‘Create a new pool and storage space’ option. Next, select the drives to create a storage pool. Remember, if the selected drives contain files you will lose them all and won’t be able to recover them from Recycle Bin.

Next, select a name, layout, and size for the storage space.

To add more disks to the current pool, simply select the drives to be added and hit the ‘Add drives’ option.

Shortly after that, you will observe the process of creating a pool in progress. Here, you can rename the pool if you would like too.

To create additional parity space, click ‘Create a shortage space and then choose ‘Parity’ from the layout options.

While creating a storage pool, if you run out of capacity you will see a notification like this:

If such a case, click on the notification to get some information and try to fix it.

That’s all you need to do to create storage Spaces and start using it like any other disk!

When you add new drives to an existing pool, it’s a good idea to optimize drive usage. This will move some of your data to the newly added drive to make the best use of the pool’s capacity. It’ll happen by default when you add a new drive to an upgraded pool in Windows —you’ll see a check box for Optimize to spread existing data across all drives selected when you add the drive. However, if you cleared that check box or added drives before upgrading a pool, you’ll need to manually optimize drive usage. To do so, type Storage Spaces in the search box on the taskbar, select Storage Spaces from the list of search results, and then select Optimize drive usage.
