RAID can be done in software on a host, such as Windows FTDISK volumes, or in hardware on the storage controllers. The downside is that there is no fault tolerance. RAID level considerations When choosing a RAID level for a new array, there are a number of important points that you need to take into consideration, including: Application performance needs.

What Is Parity In Raid

If you lose a drive in a stripe set, all access to data must be from the other stripe set, because stripe sets have no parity. Advantages Like with RAID 5, read data transactions are very fast. A RAID system consists of two or more drives working in parallel. http://magicnewspaper.com/what-is/file-system-types-in-xp-home.html With RAID 6, two disks worth of space is required for parity, so you take a capacity hit of up to 50% (four disk RAID 6 configuration).

That back-up will come in handy if all drives fail simultaneously because of a power spike. Privacy Please create a username to comment. Excellent redundancy ( as blocks are mirrored ). You get the solid redundancy and storage efficiency of a RAID 6 along with better performance, depending how many you stripe together.
