A striped volume uses the free space on more than one physical hard disk to create a bigger volume. Unlike a spanned volume, a striped volume writes across all volumes in the stripe in small blocks, distributing the load across the disks in the volume. The portions of disk used to create the volume need to be the same size; the size of the smallest free space included in the striped volume will determine.

A failure of eiher drive in a stripped volume will result in a total loss. You may be able get some data back from a spanned volume if the file is completly on one disk. You can create a spanned volume across the 2 x GB drives, giving you 1 x GB volume. Sign up to join this community. The best answers are voted up and rise to the top. Asked 8 years, 10 months ago.

Super User works best with JavaScript enabled.A spanned volume is a dynamic volume consisting of disk space on more than one physical disk. By creating spanned volume, you can merge multiple unallocated spaces of physical disks into one logical volume so as to utilize space on multiple disks efficiently.

When users need to create a volume but do not have enough unallocated space for the volume on a single disk, users can create a volume with desired size by combining areas of unallocated space from multiple disks. The areas of unallocated space can be different size. This kind of volume is called spanned volume.

If the space allocated to the volume on one disk is filled up, users can store data to the next disk. Spanned volume allows users to get more data on the disk without using mount points. By combining the multiple unallocated spaces of physical disks into a spanned volume, users can release drive letters for other uses and create a large volume for file system use. Increasing the capacity of an existing spanned volume is called "extending".

Existing spanned volumes which are formatted with NTFS file system can be extended by all unallocated space on all disks. But, after extending a spanned volume, if users want to delete any portion of it they need to delete the entire spanned volume.

Disk management tool can format the new area without affecting all existing files on the original spanned volume.

Hello friends my name is Dharmendra and today we will talk about Spanned and Striped Volume. The size of two or more disk volumes can be different and it is not necessary that they are of same size. Minimum 2 and maximum 32 disk volume can be used to create a spanned volume. When the data is saved in the Spanned Volume, the first data is stored in the first volume and when it is full, the data automatically gets stored in the second or next disk.

Thus, it utilizes the entire space of multiple disk but performance in the spanned volumes is not good. You can only extend NTFS or unformatted volume. Once you create a Spanned Volume, you can not delete any part of it. For this you have to remove the full spanned volume. You can not use the spanned disk in the use of mirror and striped volumes. Pic 1 — Creating spanned volume from two equal size basic disks.

This is made like a spanned volume, in which minimum 2 and maximum 32 unallocated disk volume can be used. It should be equal to the size of all disk volumes. If you use unequal disk to create a striped volume, then by adding the minimum disk size it creates a new volume. Striped volume do not offer fault tolerance In this case if any disc fails, then the whole volume becomes fatal and you can not access data from the striped volume.All rights reserved.

January in Server January Here's a list of terms you will come across: Dynamic Storage Terms A volume is a storage unit made from free space on one or more disks. It can be formatted with a file system and assigned a drive letter. Volumes on dynamic disks have the following types: simple, spanned, mirrored, striped, or RAID A simple volume uses free space from a single disk.

It can be a single region on a disk or consist of multiple, concatenated regions. A simple volume can be extended within the same disk or onto additional disks. If a simple volume is extended across multiple disks, it becomes a spanned volume. A spanned volume is created from free disk space that is linked together from multiple disks. You can extend a spanned volume onto a maximum of 32 disks. A spanned volume cannot be mirrored and is not fault-tolerant.

A striped volume is a volume whose data is interleaved across two or more physical disks. The data on this type of volume is allocated alternately and evenly to each of the physical disks. A striped volume cannot be mirrored or extended and is not fault-tolerant. Striping is also known as RAID A mirrored volume is a fault-tolerant volume whose data is duplicated on two physical disks.

All of the data on one volume is copied to other disks for storage. If one of the disks fails, the data can still be accessed from the remaining disk.

A mirrored volume cannot be extended. Mirroring is also known as RAID A RAID-5 volume is a fault-tolerant volume whose data is striped across an array of three or more disks. Parity a calculated value that can be used to reconstruct data after a failure is also striped across the disk array. If a physical disk fails, the portion of the RAID-5 volume that was on that failed disk can be re-created from the remaining data and the parity.

A RAID-5 volume cannot be mirrored or extended. The system volume contains the hardware-specific files needed to load the Windows for example, Ntldr, Boot. The system volume can be, but does not have to be, the same as the boot volume. The boot volume can be, but does not have to be, the same as the system volume.

Intellipower upto rpm On booting win7 it installed the necessary software I know that Spanned Volume - A dynamic spanned volume consists of two or more subdisks contiguous disk regions on one or more disks. With a spanned volume, you can combine sections of unallocated space from multiple dynamic disks into one large volume.

The areas of unallocated space used to create spanned volumes can be different sizes. Spanned volumes are organized sequentially—that is, Array Manager sequentially allocates space on each disk until that disk is full and then continues with the next disk until the volume size is reached.A spanned volume is a dynamic volume that consists of disk space on more than one physical disk.

If a simple volume is not a system volume or boot volume, you can extend across additional disks. If you extend a simple volume across multiple disks, it becomes a spanned volume. You can extend a volume only if it does not have a file system or if it is formatted using the NTFS file system.

Backup Operator or Administrator is the minimum membership required to complete the actions below. Make note of the number of the simple volume you want to extend onto another disk.

This selects the simple volume volumenumber you want to extend onto another disk. Make note of the number of the disk that you want to extend the simple volume onto.

Selects the specified volume, where volumenumber is the volume number, and gives it focus. If no volume is specified, the select command lists the current volume with focus.

You can specify the volume by number, drive letter, or mount point path. On a basic disk, selecting a volume also gives the corresponding partition focus. Displays a list of disks and information about them, such as their size, amount of available free space, whether the disk is a basic or dynamic disk, and whether the disk uses the master boot record MBR or GUID partition table GPT partition style.

Extends the volume with focus into next contiguous unallocated space. For basic volumes, the unallocated space must be on the same disk as, and must follow be of higher sector offset than the partition with focus. A dynamic simple or spanned volume can be extended to any empty space on any dynamic disk.

Using this command, you can extend an existing volume into newly created space. If the partition was previously formatted with the NTFS file system, the file system is automatically extended to occupy the larger partition. No data loss occurs.

Dynamic Disk VS Basic Disk: What's the Difference and How to Convert Without Data Loss?

If the partition was previously formatted with any file system format other than NTFS, the command fails with no change to the partition. The dynamic disk on which to extend the volume. If no disk is specified, the volume is extended on the current disk. The amount of space, in megabytes MBto add to the current partition.

If you do not specify a size, the disk is extended to take up all of the next contiguous unallocated space. Toggle navigation. Extend a Simple or Spanned Volume.

Click Extend Volume. Follow the instructions on your screen. To extend a simple or spanned volume using a command line Open a command prompt and type diskpart. Value Description list volume Displays a list of basic and dynamic volumes on all disks. You cannot extend the current system or boot partitions.

Command-line syntax notation. Table Of Contents.This post will give you an introduction of dynamic disk and basic disk, and tells you the difference between them. And teach you how to convert dynamic disk to basic disk and basic to dynamic disk. What is dynamic disk? Dynamic disk vs Basic disk. How to convert basic disk to dynamic disk? How to convert dynamic disk to basic disk without data loss? Dynamic Disk is one of hard drive configurations that most commonly used in Windows systems.

You can convert a basic disk to dyanmic disk. On a basic disk, the storage space will be divided into one or multiple partitions to keep data, while a dynamic disk sets several several segments called "volume" to store data.

And it keeps track of all volumes by logical disk manager LDMinsteading of partition tables. Data on different dynamic disk can be relatted.

When you change a dynamic disk, information will be recorded in logical disk manager, which is hidden at the end of the dyanmic disk. Before we figure out the difference between dynamic disk and basic disk, let's see what is a basic disk. It is the most common disk type used in Windows OS.

When you initialize a hard disk on your computer, it would initially set up as a basic disk. A basic disk store data on different basic partitions, or drives. You are allowed to manage storage space by resizing, deleting, extending, formatting partitions within one basic disk. Meanwhile, a dynamic disk also supports you to resize its volumes. Besides, you can share data among various dynamic disk to prevent data damage or loss.

Differ with basic disks, dynamic disks create volumes that span among up to 32 physical disks. It gives fine disk performance and flexbility by creating 5 types different volumes, including simple volume, spanned volume, striped volume, RAID-5 volume.

Creating Striped (RAID 0) and Simple Volumes using Disk Management - Windows 10

You can change the size of a simple volume on the dynamic disk. And if there are only one dynamic disk on your PC, simple volumes are only allowed to be created.

Its data are distributed in multiple disks. The next table makes a brief summary of the differences between dynamic disk and basic disk. You can take a quick glimpse at it. But it is worth mentioning that a dyanmic disk still have some drawbacks. For instance, it does not work in dual-system computer.

Next, if you want to convert your disk, Here, we are going to demonstrate how to perform the basic-to-dynamic and dynamic-to-basic conversion. Because of flexibility of dynamic disk, many people want to change basic disk to dynamic disk. But please read the above information and take its disadvantage of it into conderation before you follow the steps below. Step 1. Step 2. You can also convert dynamic disk to basic disk in Disk Management, but using DM is not recommended here, because you need to delete all the dynamic volumes during the operation, and will lose all the data on the disk.
