What is the Conception of Dynamic Disk
Dynamic disk is what and how to utilize; these questions confuse us should be clear away now. A hard drive normally being the format of Basic Disk and Dynamic Disk. Here Dynamic disk come with Windows 2000. It creates dynamic volumes and provides mirrored volume or RAID5 which possess fault-tolerant ability to offer a greater flexibility for windows server and optimize disk IO performance.
Generally, our drive exists in the type of basic disk, and it is easy to change basic disk to dynamic disk if you like dynamic.
Once you had convert basic disk to dynamic, just make full use of the advantages for instance solving the problem of inadequate disk partition by creating the mirrored volume, striped volume, spanned volume or raid-5 volume.
- A simple volume may be either single or cluster allocating space on a single disk free. If extended across disks more than one, now, it becomes a spanned volume namely.
- A spanned volume knows from a simple volume, for it is created from the space leave unused in multiple disks. And you can neither expand it over 32 disks nor mirror it, as well as no fault-tolerant.
- A striped volume also known as RAID-0, is a volume with data allocating across physical disks more than one, then its data storage be alternate. A striped volume without fault-tolerant, cannot be mirrored or expanded.
- A mirrored volume’ data is duplicated stored on two physical disks and copied to another disk to provide data fault-tolerant advantage. Once each disk plays down, the data can still be obtained from another disk. However a mirrored volume can not be expanded. Mirrored volume is the same with RAID-1.
- A RAID-5 volume a fault-tolerant volume whose data is striped across a series of three or more disks allows stripping across different disks. In case a physical disk fails, it can be re-created from the remaining data and the parity. But RAID-5 volume cannot be mirrored or expanded.
It is pregnant to apply Dynamic disk for its many advantages on operation. It’s a pity that Windows 7/XP/Vista Home Edition does not support dynamic disk, which means dynamic disk became these versions invalid.
