> **Colored Status Indicator** the significance of the color indicator at the beginning of each line in *Pool Devices* is as follows:
>
> <i class='fa fa-circle orb green-orb'></i>Normal operation, device is active.
>
> <i class='fa fa-circle orb grey-orb'></i>Device is in standby mode (spun-down).
>
> <i class='fa fa-square orb blue-orb'></i>New device.
>
> <i class='fa fa-square orb grey-orb'></i>No device present, position is empty.
>
> **Pool Devices** is a single device, or pool of multiple devices, *outside* the Unraid array.  It may be exported for network access just
> like an Array device.  Being outside the Unraid array results in significantly faster write access.
>
> There are two ways to configure the Pool devices:
>
> 1. As a single device, or
> 2. As a multi-device pool.
>
> When configured as a single device you may format the device using any supported file system (btrfs, reiserfs,
> or xfs).  This configuration offers the highest performance, but at the cost of no data protection - if the
> single pool device fails all data contained on it may be lost.
>
> When configured as a multi-device pool, Unraid OS will automatically select *btrfs-raid1* format (for both data
> and meta-data).  btrfs permits any number of devices to be added to the pool and each copy of data is guaranteed
> to be written to two different devices.  Hence the pool can withstand a single-disk failure without losing data.
>
> When [User Shares](/Settings/ShareSettings) are enabled, user shares may be configured to
> automatically make use of the Pool device in order to
> speed up writes.  A special background process called the *mover* can be scheduled to run
> periodically to move user share files off the Cache and onto the Array.
