Capacity Data Safety Performance Learn About RAID 0 RAID 1 (Mirror) Data is written at same time to two drives only for highest level of data safety and redundancy. Striping, Mirroring & Parity are the three basics of RAID levels, which we are going to discuss. From what I've read here, it sounds like RAID 10 would be preferable, but of only half of the drive is usable, would installing (4) 2TB drives result in 4TB of http://searchstorage.techtarget.com/definition/disk-striping

  6. Each of RAID levels has its own characteristics of: Fault-tolerance which is the ability to survive of one or several disk failures.
  7. It’s far from common to see RAID configurations in the average home PC, but it isn’t especially unusual either.
  8. RAID layout created by means of Windows is inseparably linked with the host operating system and so its partitions cannot be used, for example, in dual boot.
  9. Minimum 2 disks.

Capacity Data Safety Performance Learn About RAID 1 RAID 10 (1+0) Data is Striped (RAID 0) over two Mirrored sets (RAID 1) of drives for fast redundancy. What Is Raid 1 GamePlayInside.com. Software RAID Software RAID is one of the cheapest RAID solutions. For valuable data, RAID is only one building block of a larger data loss prevention and recovery scheme, it cannot replace a backup plan.

Parity:As explained above, mirroring involves high cost, so to protect the data new technique is used with striping called parity. This configuration offers no parity, striping, or spanning of disk space across multiple disks, since the data is mirrored on all disks belonging to the array, and the array can only

There are certain limitations on the use of the software RAID to boot the system. RAID3, which is rarely used in practice, consists of byte-level striping with a dedicated parity disk. ParityParity can be used alongside striping as a way to offer redundancy without losing half of the total capacity to duplicate data. http://hcsprogramming.com/raid-1/raid-0-to-raid-0-1.php Mirroring would only give you the capacity of 1 hard drive, and the exact same speed.

In the illustration below there are 4 drives set up as a RAID 5. Non-RAID drive architectures are referred to by similar terms and acronyms, notably JBOD ("just a bunch of disks"), SPAN/BIG, and MAID ("massive array of idle disks").
