RAID provides real-time data recovery when a hard
drive fails, increasing system uptime and network availability while protecting
against loss of data. Another advantage of the system is that multiple disks
working together increase overall system performance. Any individual or company
could benefit from having a RAID RECOVERY system in place.
Different Levels
There are several different levels of RAID
available. Each level offers various advantages in terms of data availability,
cost and performance. Your best bet is to assess your needs in order to
determine which level works best for you. The most popular RAID systems are the
following:
RAID 0 - Data striping (no data protection).
The benefit of this system is that it offers the highest performance.
RAID 1- Disk Mirroring (provides data
protection by duplicating all data from a primary drive on a secondary drive).
The benefit of this system is it offers the highest data protection.
RAID 0/1- This combines both Raids 0 and 1. The
benefit here is highest performance + highest data protection.
RAID 5 - Data striping with distributed parity
(a form of data protection that recreates the data of failed drive in a disk
array). This system offers the best cost performance for multidrive
environments.
Having a RAID system installed can provide
peace of mind. With RAID installed you can rest assured that even in the event
of a system failure your important data will be safe.
