Setup RAID Configuration

Welcome to PMX Computing!  Our main goal is to help you with your computing needs.  Let us help you setup RAID Configuration.


What is RAID?  RAID (Redundant Array of Independent Disks; originally, Redundant Array of Inexpensive Disks) is a way of storing the same data in different places (thus, redundantly) on multiple hard disks. Up your performance!  By placing data on multiple disks, I/O (input/output) operations can overlap in a balanced way and improve performance. Use multiple disks.  Since multiple disks increase the mean time between failures (MTBF), storing data redundantly also increases fault tolerance.


"Data is the most valuable asset of any business today."


RAID-0: Is the fastest and most efficient array type but offers no fault-tolerance.
RAID-1: Is the array of choice for performance-critical, fault-tolerant environments. In addition, RAID-1 is the only choice for fault-tolerance if no more than two drives are desired.
RAID-2: Is seldom used today since ECC is embedded in almost all modern disk drives.
RAID-3: Can be used in data intensive or single-user environments, which access long sequential records to speed up data transfer. However, RAID-3 does not allow multiple I/O operations to be overlapped and requires synchronized-spindle drives in order to avoid performance degradation with short records.
RAID-4: Offers no advantages over RAID-5 and does not support multiple simultaneous writing operations.
RAID-5: Is the best choice in multi-user environments which are not write performance sensitive. However, at least three, and more typically five drives are required for RAID-5 arrays.
