#Can softraid do raid 6 software#
Software RAID support has been available in the Linux kernel since version 2.0, although the first version was hardly suitable for practical use: its capabilities were very limited and it contained a fair number of bugs. But for now, Linux does not supports the RAID 0+1 level.Īt least three disks are required for RAID 5. For this reason RAID 5 was considered the most efficient and economical level until new developments in this area such as RAID 5EE, RAID 6, RAID 10 and the combined RAID 1+0, RAID 5+0, RAID 1+5 levels were introduced. RAID 5 separates both data and parity information during writes. For this reason it is recommended to use RAID 5 in all cases except those in which the use of RAID 4 is extremely necessary and justified. Therefore, the weak point of this subsystem is the wait time for writing to this particular disk. The feature of RAID 4 is a separate disk for writing parity information. Reliability is increased, but write performance is reduced because the same data is written multiple times.
This mode is often called “mirroring” because data is duplicated on all disks in the array. RAID 1 is the first level that provides redundancy. With RAID 0, two or more disks are used only to increase performance by separating read/write data between them. However, software RAID can be very useful and Linux has all components needed to create a software RAID system. A hardware RAID subsystem is the most efficient, both from the reliability and performance standpoints.

RAID is Redundant Array of Independent Disks (although a free interpretation is probably more correct: an array of redundant independent disks) is a hardware or software subsystem in which stored data is distributed (often with redundancy) across multiple hard disks (physical or virtual).

One of the tools to help solve the data storage problem to a certain extent is based on the creation of RAID disk arrays. Especially nowadays, when the amount of stored data is growing at an extra rate, regardless of whether this data is personal (the photo and video collections) or corporate (financial and project documentation, scientific research results, etc.). The importance of reliable data storage is obvious to any level of user.
