RAID is short for redundant array of inexpensive disks. In storage technology, it is a way of storing data on two or more disk drives while creating a logical storage unit. It increases performance and fault tolerance because of some data redundancy. Nowadays many motherboards are equipped with built-in RAID. However, it is not necessary for personal computers. RAID can duplicate data among hard disk drives, which is more critical in corporate environments.
There are several types of RAID commonly known as RAID levels. Level 0 until Level 6 RAID are distinct to each other by each level’s data placement patterns and degrees of redundancy. RAID can be utilized as either a hardware RAID or software RAID. Generally, few problems are encountered by people that use RAID. However, when problems arise, RAID recovery becomes a major headache.
When there is a RAID failure, professional RAID recovery is essential, says Phil Nevis of Hard Drive Recovery Group. Initially, jot down all the details that you know regarding original array configuration. For hardware configuration, label the disks using a marker. The controller ports and cables must also be labeled properly. You can use numbering style to specify the different disks. Generally, it is important to label the cables, ports, disks and other equipment clearly. Read the rest of this entry »
