RAID level 5 uses striping, which means, the data is spread across number of disks used in the array, and also provides redundancy with the help of distributed parity. RAID 5 is the best cost effective solution for both performance and redundancy. Minimum number of disks required for raid 5...

A RAID 5 array requires a minimum of three disks. Regardless of thenumber of disksthat exist within the array, the equivalent of one disk's capacity will be lost to parity-related overhead. As such, a three-disk RAID 5 array will provide users with the combined capacity of two disks. ...
When you need torebuild a RAID5 array and why you need to back up Minimum drives for RAID 5is 3. Rebuilding aRAID 5array is necessary in cases where one disk of the RAID 5 array stops working, even if it does so temporarily. Of course, that is only one drive; you can work well...
disks, a 1:1 clone of the data is produced. If only one disk fails, the data is totally safe, and the array may be rebuilt by adding the replacement disk.Enterprise storage solutions like SAN and NAS devices frequently employ RAID 5. (striping with parity). For the optimal speed, data...
Data is allocated on RAID hard drives in different ways, referred to as RAID levels, including RAID 0, 1, 2, 3, 4, 5, 6, and 10. The explanations of commonest RAID levels: Advantages of RAID Generally, RAID uses multiple disks working together to increase overall system performance for...
Disks: A minimum of two disks are needed to support striping. Type: Any disks involved in striping must be dynamic. Conversion from basic to dynamic goes very quickly without data loss. After you complete the conversion procedure, you must restart the computer. ...

To use RAID 0, a minimum of two hard drive disks are required. The following illustration provides a visual example of a RAID 0 configuration. Drive A Drive B Segment 1 Segment 2 Segment 3 Segment 4 Segment 5 Segment 6 Segment 7 Segment 8 RAID 0 Example RAID 1 RAID 1 allows identical...
