Why A Raid 10? Let Us Explain; RAID Recovery.

Redundant Array of Independent Disks (RAID) is a method of storing information on multiple hard disks for the purpose of superior protection, reliability and efficiency. There are different levels of RAID storage methods, varying from 0 to 9 and each is optimized for a specific purpose. It is possible to combine two levels which forms a two digit RAID level that produces a greater performance. RAID 10 is a combination of level 1 which is specific for mirroring and level 0 which is striping. Mirroring simply means that an exact set of value from one disk is copied to another disk with comparable strength or intensity. It is assumed that if one disk fails, the other disk preserves the data from the corrupt or failed disk but that doesnt mean you wont need RAID recovery. Striping or a stripe set, on the other hand, is the splitting of data into chunks and evenly distributing them in succession into two or more disks with the absence of redundancy. This on its own improves performance because your computer can effectively access each data simultaneously.

The Difference between RAID 10 and Other RAID Levels

Effectively combining these two levels equips RAID 10 with speed and resilience. So the question is why use RAID 10? Why not RAID 5 or 6? Well unlike RAID 5 or 6, RAID 10 gives you Up to 6TeraByte of total capacity, a performance advantage, resilience and redundancy that shields and protect you to a very large extent from a single drive failure. In fact, it is impossible to lose a file except the original file was corrupt before copying.

Another superior advantage of RAID 10 is the recovery or rebuild process.  A RAID can be constructed from Physical disks, disk image Files or a combination of both physical drives and disk image files. Unlike RAID 5 which needs to read every single data on all the remaining drives to rebuild the new disk, RAID 10 solely reads the uncorrupted or unaffected mirror and stores the copy to the newly replaced drive but the usual read and write operations remains unchanged. This process can take less than 30 minutes for drives of 1 Terabyte.

Implementing RAID 10

To properly execute RAID 10, a total of at least four physical hard drives is required. You also need a disk controller that supports RAID. It is important to always use identical disks when creating a RAID 10 array. The disk geometry is key and it is strongly recommended NOT to use dissimilar disks. Since the costs of disks are decreasing as technology evolves, ensuring safety and efficiency in storage capacity is now less expensive than before.

RAID 10 is relatively easy to configure and it only takes a few minutes. The system or disk controller software includes install routines that only needs you to follow the prompt.

Is RAID Back-Up?

Note that RAID is not a substitute for back-up. For complete protection, there is a need to back-up the data from a RAID system. This back up will come in handy in a case where all the drives fail simultaneously because of a power spike than you will need RAID recovery which can be in the thousands of dollars, if the storage system gets stolen or in the case of user error.
