RAID 3 supports byte-level data striping across multiple disks. It implements fault tolerance by sending parity information to a disk dedicated to store parity information. As compared to file system block, the strip across the disk is quite smaller. So, all the read/write operations are performed at high performance rate. RAID 3 can tolerate failure of one hard disk. It simply implies that when a single point failure occurs, the dedicated parity disk does not show it. RAID is used in enterprises for storing critical business information. Thus when it fails,
RAID Recovery Services come as rescue to extract all possible information from failed array.
One of the main ideas of implementing RAID 3 is to have a high-performance system. On the other hand, implementing dedicated parity disk makes sure that array redundancy will be maintained. One general setup of RAID 3 can include 3 hard disks, two for striping the data and one for holding parity information. However, the use of parity makes is compelling to write parity whenever the data is written. This necessitates the use of hardware controller. Since the stripe size is small, it is ideal for applications that use large files.
When more than one hard disk fails, it negatively impacts the RAID performance. It cannot come to a stable state, until the lost data is recreated from the parity information. RAID 3 is susceptible to same kind of damages as other hard disks are. The ailments like virus attack, natural disasters, human errors and operating system crash can fail this array. Moreover, the additional complexities can introduce more types of failure like loss of parity information, registry configuration loss, RAID reconfiguration, controller failure and more. While such situations, if you cannot recover from the backup, youll need to a consult
RAID Data Recovery Company.
RAID Recovery Services is provided through highly sophisticated techniques and advanced set of tools. In technical terms to recover RAID 3 array, they apply techniques like image compression, removing the hard disks and dealing with RAID as a stripe. Such companies provide you high success rate using special software and hardware processes to recover lost data.
