A general hard disk and a RAID hard disk is different in terms of operation. The primary reason of RAID is to contain data redundancy rate and provide better performance, so the greater the redundancy rate, the greater the performance is. RAID means ‘Redundant Array of Independent Disks’, formerly well-known as economic disks.
Its functionality is generated by multi-disk combination technology in one logical module. According to data redundancy rate and different performance across situations, there are some levels of how data redundancy rate and performance are affected. The RAID system is distributed by numbers for better organization: RAID 0 has minimum tolerant and redundant, while RAID 6 offers two level error recovery. RAID 5 is a disk configuration using disk marking with parity. In case of Raid 5 data recovery, data reconstruction is easy.
According to the number of RAID, the complexity or ease of data recovery varies. If a disk is in the RAID 0, then all disks are in this category and the data can no longer be recovered. This is mainly a system that uses more than one data storage location that pushes parity. The best Raid 0 data recoveryis only offered by some of most unique companies such as Salvagedata.
System of RAID systems is divided into two groups according to the RAID nature plus the RAID numbers: there are Hardware and Software RAID.
Differences between Raid Hardware and Software
Hardware RAID consists of a hardware-based system. It is built and manufactured to house the RAID system that can work with RAID card or is directly integrated into the Motherboard. In such system, separate discs are required but the Raid system considers all discs as one. The resulting capability of RAID disk depends on number of disk drives and RAID level. Generally less number of disks are used with higher number Raid and vice versa because a large disk space is, making data recovery process is much simpler.
RAID Software, as name implies, is software-driven and there’s not any need of hardware to configure RAID disks originally. In a system, there’re tools such as Device Manager that allow you to more effectively manage each hardware component. Software has already progressed to the point where we can manipulate the hardware function through advanced software. The RAID software is generated by distributing spaces to different disks in order to create a virtual RAID disk.
