How to Set Up RAID Disk

How to Set Up RAID

RAID is an acronym for Redundant Array of Independent Disks. RAID is a system that allows two (2) or more disks to be physically linked together to form one logical large capacity storage device that enhances the use of conventional hard disk storage devices. RAID offers superior performance improved resiliency and lowers cost. This is done through either increase disk performance or improved data reliability. There are two kinds of RAID systems that one can place on one’s computer system, namely, RAID0 and RAID1. Because RAID can improve upon conventional hard disks in one of two ways, the objective hope to be achieved will help to determine if persons will opt for RAID0 or RAID1. RAID0 is also known as data striping and is used when one would like to improve the performance of one’s hard disk performance. On the other hand, RAID1 does not improve performance as RAID0 does, but instead improves data reliability by mirroring the hard disk and backing up the information. Should the hard disk fail, the second back up copy would immediately take its place. Herein is one of the benefits of setting up a Redundant Array of Independent Disks. Users wishing to use a RAID 0 system on his or her computer system may consider the following guidelines.


1. First step to creating striped RAID is having two (2) unpartitioned unformatted hard drives with the same amount of free space. It is best if the two (2) hard drives are identical in manufacturer and make. Use the non-magnetic Philips screwdriver to remove the back panel so that the hard drives and the plug in SATA cables may be installed.
2. After installing the adapter card and hard drives in the Computer, users should begin to configure the adapter card and hard drives. This is also known as card BIOS.
3. After installing the data cables and the two (2) hard drives, persons prepare to format the computer. This part of the setup will need the Windows Installation disc along with the SATA/RAID floppy disc. The need for the RAID floppy disc is unique to installing a Windows XP operating system on the array. This is not necessary with Windows Vista.
4. Users can now begin formatting by turning on the computer and inserting the CD. After inserting the CD, shut down the computer.
5. Restart the computer and enter the bios by pressing delete or specified key (such as esc) while the computer is still booting.
6. In the BIOS, find and enable RAID ports that are being used. Exit the BIOS and get ready to push the F10 key (or the specified the key) to enter the Flash/RAID BIOS.
7. When one has entered RAID BIOS, set the stripe/mirror section to Stripe to 16kb or 32kb. Next, move the hard drives (as shown on the screen) to the array. At this point the RAID will prompt users to clean the drives, users should comply by selecting yes. Exit RAID BIOS.
8. After exiting RAID BIOS, Windows Installation setup will begin. Users will then be prompted to press F6, users should again comply and insert the RAID floppy disc at this point. The process of formatting the computer. Users should do the long format.


RAID 0 provides no real data protection but instead encourages the loss of data and so is not a very secure RAID to use.
The larger the kb is set when configuring the Stripe, the faster the RAID will be. However, users will have less space efficient use of hard drive space.
