RAID Data Recovery
RAID Data Recovery Services for RAID 5, RAID 6, RAID 0, and RAID 1Although RAID systems are typically implemented for data security reasons, no system is 100% secure. For example, if a virus attacks a RAID system with redundancy, it attacks all copies of the data rendering the entire system useless. At Gillware, RAID data recovery is done by recovering data from individual failed disks and then reassembling it based on the type of RAID system. The end result is you getting your files back. And of course, there is no fee if we are unable to recover the system. Many of today's applications demand data storage with four main attributes: high security, high availability, high capacity (terabyte level), and high performance. These attributes cannot be found in any single-disk storage system. In 1987, researchers at the University of California at Berkeley developed the concept of multiple-disk storage systems and coined the term "RAID" or Redundant Arrays of Inexpensive Disks. "Inexpensive" is often used interchangeably with "Independent". Data security is the reason most RAID systems are created. A company's data is its blood and it can't live without it. High security is created through the use of redundancy. Most RAID systems can withstand failure of one (sometimes more) disks without losing any data. The data may have to be reconstructed, but it is not lost. High availability in RAID systems comes from the RAID controller's ability to switch to a redundant copy of data in the event of a drive failure. The failure is not transparent to the users since performance is usually degraded in this "limp along" state. RAID systems achieve high capacity simply by using multiple disks. With most RAID systems, the storage efficiency (the ratio of the RAID system capacity to the total capacity of all individual disks) is less than 100%. This is because most RAID systems keep redundant copies of the data and this data must be stored somewhere. It's intuitive to think that the storage efficiency of a RAID system with redundancy should be 50% but with the proper configuration, it can be much higher than that. See our RAID 5 page to see an example of how this is possible using the XOR binary operator. All RAID systems use the capabilities of multiple disks to improve performance. Performance is enhanced in different ways depending on the configuration. For example, since RAID 1 systems keep an exact redundant copy of data on another disk, they can read a file much faster since they read different parts of the file from each disk. RAID 0 arrays improve read and write performance by splitting files into pieces and storing the separate pieces on multiple disks. It is important to note that not all RAID systems have all of these attributes. For example, RAID 0 does not provide any increased security or availability when compared to a single disk. RAID 0 systems are built for performance and capacity only. For many years, RAID systems were used almost exclusively in high-end corporate data systems where cost of the system was not a concern. In recent years, the number of RAID users has grown dramatically. The development of inexpensive controllers that are compatible with standard IDE/ATA drives and the increased capacity, security, and performance requirements of many users have contributed heavily to this growth. You may own a RAID system and use it everyday without even knowing it. For example, many high capacity external drives are nothing more than self-contained RAID 0 systems. We have technicians that specialize in RAID reconstructions and a wide variety of tools to accomplish the task. We also have the ability to develop custom programs to reconstruct systems of odd configuration. Please call 877.624.7206 for a quote.
