When talking about External RAID arrays, it often sounds daunting and overwhelming having to work with them. Storing information and maintaining a well-functioning system could be puzzling as well!

Though, if used efficiently, External RAID arrays can prove to be highly beneficial for users. This article will help you better understand what they are. 

In this article, we will walk you through the workings and applications of an External RAID array for its superior usage. Further, this article will also help you to understand the differences between an internal and an external RAID array and the precautionary steps for a fail-proof setup. 

 

An External RAID is a data storage technology that enables the user to connect two or more hard drives in the same machine. It makes the array look like a single volume for better storage and superior performance.

 

The RAID hard drive works diversely depending on the option chosen. RAID 1 works by mirroring identical information throughout the stack. Whereas, RAID 5 works by striping the data uniformly across the hard disks (HDD) via the parity function. Similarly, the RAID arrays are a combination of different functions, which are mirroring, parity, and striping. 

The hard drives in an External RAID can be increased for a better experience and undisturbed work operations. In the case of RAID 0, the increased drives also help to improve speed. And in the event of a RAID 0 drive failure, a spare hard drive is crucial.

 

An External R A I D comes in handy when the storage capacity of one drive is insufficient and the files don’t fit in the limited number of drives. Despite the outside work operations, an External RAID hard drive can assist you when you plug the array back into the computer. Hence, tasks like editing are still possible even though they are created externally.

An External RAID drive could be used to increase data storage, data redundancy, and data protection. High-end work operations like multimedia files, photography, and gaming require extra space, especially more than one drive.

Controllers in a lot of new systems offer the function of a USB hard drive. A USB 3 provides good speed, good storage, and a low price with a RAID 1 and 0 implementation. Operations with crucial data are helped by a USB 3 in RAIDs.

 

RAID 5 and RAID 6 are two of the most appropriate RAIDs and come with a good amount of speed and data protection. They are used not only for high-end multimedia tasks like video editing, photo editing, and gaming but also for business purposes and consumer uses. Along with its other benefits, cost efficiency is yet another added advantage.

RAID 5 uses one hard drive for parity whereas RAID 6 uses two drives. 

RAID 0 is the best option for speed-intensive tasks. Though, in instances where one hard drive fails in a RAID 0, the files in the hard drives are permanently deleted due to zero redundancy. Hence, it is advised to refrain from storing crucial data on RAID 0. 

A RAID 1 and RAID 0 are not recommended since the former uses lesser drives and the latter has no guarantee with regards to protection from data loss.

In an external RAID hard drive, expansion is way easier than in an internal RAID array. In case you have maxed out your internal storage, an external storage drive comes in handy. In comparison to the external array, an internal array also lags in terms of speed. This helps conclude that stripping both external and internal RAID together for purposes of speed is simply not an option. 

Lack of protection is yet another factor that limits an internal RAID array. An External RAID array on the other hand comes with plenty of protection options.

To summarize, an External RAID array is a better option in terms of steady storage, but when combined, external and internal RAID arrays offer better speed.

 

To be careful with an external RAID hard drive means to make sure to not only use a RAID controller that supports the type of RAID installed, but also one that is of good quality. Ensure that the RAID controllers aren't varied, in which case, combining multiple hard drives could be a problem. In case the RAID controller fails, the RAID drives need to be set up in another enclosure or system with the correct sequential order of the drives maintained. 

It is also important to monitor the condition of the system from time to time and decrease the burden on the computer by deleting any obsolete files.

In case of failures, it is suggested to reach out to professional data recovery services.

A RAID hard drive should never be confused with a backup. And RAID hard drives don't protect against factors like user negligence, viruses, controller faults, power surges, etc. Theft and hacking are yet another matter of concern with the possibility of invaluable files getting stolen and recollecting all the files back will be an overwhelming task.

A copy of the data is a practical option saved in a separate recoverable volume in case data needs to be set up in another operating system. A backup from time to time ensures the latest copy of all the contents is available and makes sure that nothing is lost due to accidental deletion, so work remains uninterrupted.
