This level of RAID is normally for live stream caching when speed is more important than the loss of data.ĭisks – minimum 2. The two disks appear as one, so when one is damaged, data loss occurs as the array is broken. It can’t however allow redundancy or copy data or hold parity information. This is known as stripping and gives a better performance. RAID 0 Disk striping – One file can be read from many disks allowing capacity and speed from all. A level higher than RAID 0 will protect against read errors and entire physical drive failures.Īll levels can be important at times and you need to find out which one is applicable for raid data recovery. Each layout is allocated its own name, for example RAID 1 or RAID 0 with each level giving balance between each of the key goals of capacity, availability, reliability and performance. Sometimes it is aimed at both scenarios.Īs data is sent across the drives and each way is known as a RADI level. RAID – also known as redundant array of independent disks – is a form of storage that joins numerous disk drive components into one unit to achieve performance improvement or data redundancy. They comprise of a few parallel disks covered in a case, actuator, actuator axis, actuator arm, platter, spindle, head, and the power and IDE connectors. Hard drive is a specific component in a computer's data storage.
