Which raid technology is used today?

As a rule, the most common RAID levels in use today are:No RAID - logical data volumes exist within single physical driveRAID 0 - logical data volumes striped across multiple physical drives with no parity/data protection. Common, but not necessarily a good idea (backup is important here).RAID 1 - logical data volumes mirrored, bit-for-bit, between two physical drives (in come implementations, additional mirror drives can be created)RAID 5 - logical data volumes striped across multiple drives with parity/data protection generated and distributed among all drives in the RAID set.Three notes come to mind:Depending on implementation, RAID devices appear as a logical (or physical) drive to the OS or application. Software RAID, configurable in utilities such as in Windows Disk Manager or MDADM (Linux) works just below the operating system, providing a representation of a virtual physical disk to the operating system.Sometimes, RAID levels are combined, such as RAID 0+1 (striped, then mirrored) or RAID 1+0/10 (mirrored, then striped).As drives and RAID sets get larger (2-3 TB+), the time to recalculate/recover data for a failed physical drive becomes prohibitive, both in downtime/degraded operation and vulnerability to data loss from an additional failure.A number of new technologies, as well modifications to classic RAID, are being explored to address shortcoming 3.
