    What is RAID?


    RAID RAID (Redundant Array of Independent Disks) is a data storage virtualization technology which can combine multiple physical disk drive components into a single logical unit for the purpose of data redundancy, or performance improvement, or both. So it owns many advantages over the use of single hard disk: higher data security, fault tolerance, improved availability, increased and integrated capacity, and improved performance.

    RAID is frequently used in Windows Server. And its main consumers include average user who want to back up data, digital audio and video production companies, financial industry that need to keep important customers’ data, and more. The same with single hard drive, a RAID virtual drive may also run out of space or you need to resize RAID partition to meet your further need one day. The following is a real life example:

    I have a new Dell Poweredge T320 with the 710 RAID controller. It has two 500 GB hard drives in a RAID1 configuration. 80 GB is allocated to the C (OS) drive, and the rest to D, a data drive. I want to resize the C drive to 120 GB to have head room. How should I go about doing this?
    Thanks in advance.
