What is Dynamic Disk

Concept of Dynamic Drive

The Dynamic Disk is known as a physical disk that manages its volumes by utilizing LDM database. What’s the LDM database? LDM is a nickname for of Logical Disk Manager, and it is a concealed database which dimension is 1MB by the end on the Dynamic Disk. The 1MB space records all the details of the volumes on a single drive, as well as holds some related information on each dynamic disk. Such as Drive Letter, Volume Label, the begin sector of Volume, Volume size, the computer filesystem of Volume, and the current dynamic disk is what one et cetera.

Each dynamic disk will store a these information mentioned if there are various dynamic disk on your computer. This means that all dynamic disks are related. The relevance of each one dynamic disk let you will see a “Missing” disk which is shown in Windows Disk Management if you remove a dynamic disk out of your system. All this is saved in LDM database, so LDM database is vary important simillar to Partition Table of Basic Disk.

You are able to convert the basic disk to dynamic easily, but Dynamic disks could not be appropriate in some instances that you need, and that means you require convert back to basic disk. Using Dynamic Disk Converter will be to safely convert dynamic disk to basic disk.

Volumes of Dynamic Disk

On Dynamic Disk, the volumes are put into Simple Volume, Spanned Volume, Striped Volume, Mirrored Volume and RAID 5 Volume. They have drive letter and volume label to differentiate.

    * Simple Volume

      The simple volume only could be created within the single disk as partition of Basic Disk, nonetheless its space can be inconsecutive.

    * Spanned Volume

      It is created from free space which is linked together from several disks (up to 32 disks). The sequence of writing data for Spanned Volume is that the volume within the first disk is filled full and then turn to fill the next dynamic drive. Spanned Volume allows the fragmentary free space of multiple disks is recomposed as one volume, so it can make full use of the resources of multi-disk. However, it cannot be fault-tolerant volume and will not improve performance on the disk.

    * Striped Volume

      It’s similar with Spanned Volume, and is made of two and more disks. However, the difference is that it could enhance the efficiency and performance of disk, because when os writes data to Striped Volume, this data will be separated into many pieces of 64KB, after which concurrent writesa different data block to each disk. A striped volume cannot be mirrored or extended and it is not fault-tolerant.

    * Mirrored Volume

      We are able to simply realize that Mirrored Volume is a duplicate of Simple Volume. It needs two disks; one stores the data which is being used, and another keep a copy of previous one. When a disk fails, one other one can be utilized immediately. A Mirrored Volume provides fault-tolerant, and it’s also generally known as RAID-1.

    * RAID-5 Volume

      A RAID-5 demands three disks at least; it not just may improve the efficiency on the disk and also provide the best fault-tolerant. You could simply consider RAID-5 is a combination of Striped and Mirrored Volume. A RAID-5 volume can be described as fault-tolerant volume whose data is striped across an array of three or more disks. Parity (a calculated value you can use to reconstruct data after a failure) is also striped surrounding the disk array. If your physical disk fails, the portion of the RAID-5 volume which was on that failed disk can be recreated from your remaining data and parity.
