RAID provides high performance to our computer users, especially server users but it also brings us with much trouble. For example, we might be troubled to manage RAID partitions such as resizing or moving them. Luckily we could solve the problem quickly and easily with magic Partition Manager or by adding hard disk. However, when we encounter data loss due to system crash, virus attack or power failure/surge, it will get serious because it causes greater loss if we recover data from raid at random, therefore, we should get help from professional raid recovery software, which is the first choice because of its quickness and safeness. Here is the tutorial to recover data from raid with reliable raid recovery software.
Basic Knowledge about RAID
Before we start to recover data from raid with raid recovery software, let's learn some knowledge about RAID.
RAID is an acronym for Redundant Array of Independent Disks. It is a method of combining several hard disk drives into one unit. This method offers fault tolerance (the ability of a system to continue to perform functions even when one or more hard disk drives have failed) and higher protection against data loss than a single hard drive. Another advantage of RAID is that multiple disks working together increase overall system performance.
Different Levels of RAID
There are several different levels of RAID available. Each level offers various advantages in terms of data availability, cost and performance. Our best bet is to assess your needs in order to determine which level works best for you. Here we introduce some commonly-used RAID levels
RAID 0 - Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple disk drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.
RAID 1 - Mirroring Volume: Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.
RAID 5 - Block Interleaved Distributed Parity: Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of RAID.
RAID 10 (or RAID 0+1) - A Mirror of Stripes: Not one of the original RAID levels, two RAID 0 stripes are created, and a RAID 1 mirror is created over them. Used for both replicating and sharing data among disks.
