RAID Hakkında
Defini bekliyoruz
RAID (Redundant Array of Independent Disks, originally Redundant Array of Inexpensive Disks) is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both. RAID levels are specific ways of organizing data across these multiple disks. Common RAID levels include RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity), and RAID 6 (striping with double parity). RAID 0 distributes data across all disks without redundancy, offering the highest performance but no fault tolerance; if one disk fails, all data is lost. RAID 1 writes identical data to two or more disks, providing excellent redundancy but at the cost of usable capacity (e.g., two 1TB drives yield 1TB usable). RAID 5 uses block-level striping with distributed parity, balancing performance and redundancy, requiring at least three disks. RAID 6 extends this by using two distributed parity blocks, offering greater fault tolerance against multiple disk failures, requiring at least four disks. More complex levels like RAID 10 (a stripe of mirrors) combine the benefits of striping and mirroring. The choice of RAID level depends on the specific requirements for performance, data availability, and cost. Hardware RAID controllers offload the processing of RAID calculations from the CPU, often providing better performance and reliability than software RAID implementations, which rely on the host system's CPU and operating system.

RAID is like having multiple notebooks for your important notes. Some ways of using them make sure you can still read your notes even if one notebook gets damaged (redundancy), while other ways let you write things down faster by using all the notebooks at once (performance).
