For servers that are used simultaneously by many people, this may not be acceptable. Raid 1 Vs Raid 5 For home usage, RAID 0 is interesting if you are after speed or RAID 1 if you want security.

Hamming-code parity is calculated across corresponding bits and stored on at least one parity drive.[13] This level is of historical significance only; although it was used on some early machines (for CRU-Inc.com. The way in which you configure that fault tolerance depends on the RAID level you set up. his comment is here Downside: It takes only one drive to fail and the entire array is affected. Performance on RAID 0 is better than having a single drive as the work is split between

IBM. 1960. Additionally, write performance is increased since all RAID members participate in serving of the write requests. Is it a 6GB/s transfer speed or any other?

Cargando... RAID works best for drives with the same capacity and using the same (type of) controller. Advantages If something goes wrong with one of the disks in a RAID 10 configuration, the rebuild time is very fast since all that is needed is copying all the data OpenBSD.org.

Each schema, or RAID level, provides a different balance among the key goals: reliability, availability, performance, and capacity. Software RAID can be implemented as: A layer that abstracts multiple devices, thereby providing a single virtual device (e.g. Why not use a separate harddisk docking station for the off-site copy? Or if that's just too big and if one drive fails due to corruption they both fail as they're mirrored.
