2.1.5 This Unraid Server OS release has been withdrawn.

2.1.1 Too many disks missing from the array.

Such array is meant for better performance rather than safe data storage. Reliability of the set depends on reliability of every disk. As this array is not redundant, there is no recovery procedure when one of the physical disks fails. Failure of any disk results in the crash of such array. Data is broken into blocks and written to several disks at the same time. Creating a spanned volume can solve the problem with size of a local disk.Ī Striped Volume is an array without redundancy. Spanned volumes have better performance than simple volumes, but their resiliency is the same.

If you create a spanned volume including 150 Gb from one hard disk and 250 Gb from another hard disk, in This PC folder you will see a local disk of 400 Gb. It consists of at least two unallocated spaces in two hard disks that are combined into one unallocated space.

It is not a storage space in the meaning that we use in this article.Ī Spanned Volume unites the free space in two or more physical hard disks into one logical drive. It is nothing but an ordinary logical drive on a physical disk. Such drive will have the name and letter which you have assigned to it, and it will look similar to other drives.įor example, a Simple Volume is a part of the physical disk that operates as a separate physical block. The storage space you have created will be shown as another drive in the folder This PC.

This option is for cases when the available size of connected physical disks is full and the user can connect another drive without the need to make changes to the storage configuration.Īfter that, click on “Create storage space”. However, you can set up a larger size for a storage pool.

A Parity storage space will protect data if one of the drives fails, and it will have a larger size than a two-way or three-way mirror, but it will work slower.ĭepending on the resiliency type you have selected, the wizard will set the maximum size of the storage space. Two-way mirror suggests storing two copies of data on a drive, and Three-way mirror – three copies. To create a large storage pool without drive failure protection, select Simple (no resiliency). Specify the resiliency type: Simple (no resiliency), Two-way mirror, Three-way mirror, Parity. You can create a storage space with the special menu in the Control Panel. However, because of the need to compute checksums, parity spaces are noticeably slower to write data, and that is why they are recommended for storing data archives. Data is written to several physical disks, with one or two parity data files created.

Parity is a kind of cross between simple and mirror types.

This type is good for storing important data in case of possible hardware failures. If one of the physical disks within a storage space fails, the copy of data will still exist on another disk.

Mirror is meant to keep data safe in case of a physical disk failure, by saving several copies of files.

Such type is convenient for temporary storage of large amounts of data. If one of the physical disks within a storage space fails, the data will be lost. In such storage space, Windows will keep all data in one copy. Such storage space type does not protect data in any way against possible failures or break-downs.

Simple It is meant to create a pool of maximal size.

After you have created a storage pool of two or more physical disks, you can create spaces in three types of resiliency: Using the Storage Spaces function, you can create a storage pool out of two or more physical disks uniting them into one group. In order to create a storage space, a computer should have at least two physical disks connected, including built-in or USB drives.

Storage spaces are available in all versions of Windows 8 and 10, including Home versions. This feature first appeared in Windows 8, and it was improved in Windows 10.
