How to Extend RAID Partition in Windows Server 2003/2008/2016?

RAID, an acronym for Redundant Array of Inexpensive Disks or Redundant Array of Independent Disks, is a technology that allows high levels of storage reliability from low-cost and less reliable PC-class disk-drive components, via the technique of arranging the devices into arrays for redundancy. Hardware RAID storage device has many advantages in the application of data processing and data storage. Therefore, it is widely used in many different fields. There are three standard RAID levels below and many non-standard levels (such as RAID 0+1, RAID 1+0, etc.). You will have a better understanding about hardware Raid and its utilities after you read this tutorial.


Striped disks (RAID 0) distribute data across multiple disks in a way that gives improved speed at any given instant. If one disk fails, however, all of the data on the array will be lost, as there is neither parity nor mirroring. RAID 0 does not implement error checking so any error is unrecoverable. More disks in the array mean higher bandwidth, but greater risk of data loss.


RAID 1 mirrors the contents of the disks, making a form of 1:1 ratio realtime backup. The contents of each disk in the array are identical to that of every other disk in the array. A RAID 1 array requires a minimum of two drives.


Striped set with distributed parity or interleave parity requiring 3 or more disks. Distributed parity requires all drives but one to be present to operate; drive failure requires replacement, but the array is not destroyed by a single drive failure. Upon drive failure, any subsequent reads can be calculated from the distributed parity such that the drive failure is masked from the end user. The array will have data loss in the event of a second drive failure and is vulnerable until the data that was on the failed drive is rebuilt onto a replacement drive. A single drive failure in the set will result in reduced performance of the entire set until the failed drive has been replaced and rebuilt.

RAID is useful for data storage and reliability. Meanwhile, RAID partition will maximize RAID performance as well as optimize its data reliability. Thus, we suggest using a stable and safe disk utility to manage your RAID Partition in windows server 2003, and Partition Assistant Server Edition is the one.

Partition Assistant Server Edition is designed for compatibility with all levels of hardware RAID, especially designed to help users easily and safely extend RAID Partition in windows server 2003/2008, etc. All you have to do is few clicks. Besides, it is safe to extend RAID Partition as required with data untouched. Extending RAID Partition in windows server 2003 will not cause performance degradation, nor will any data be lost during the partition process.
