4 Different Myths of RAID You Must Know
Where one can have ample options to choose from when it comes to data storage, some people are smart enough to select RAID (Redundant Array of Independent Disks). RAID is considered as one of the popular data storage technologies which can be used by the business owner or a regular computer user.
People rely on RAID because it offers more flexible data storage options and reliable backups as compared to basic storage methods. With the availability of diversified RAIDs, using one can enhance your computer’s storage performance.
Though RAIDS are convenient, yet they are not ideal. Data recovery specialists have made many RAID data recoveries too. People who are using RAID might not have the correct knowledge regarding every aspect of RAIDs, and incorrect usage of it can affect your data and computer systems. So here are some of the myths related to RAID that you must know-
Myth1- All RAIDs are Redundant-
People choose RAIDS because of the two main factors- redundancy and performance provided by them. It is true because most of the RAIDs provide redundancy, which means that the same data can be present on various drives and systems. Having redundancy is beneficial for the users and of course data because if one drive fails, your data remains on other drives without any loss or interruption. Secondly, you can always swap old drives before they crash with any hindrance in work, leading to better physical maintenance.
Although RAIDs come with many advantages, yet not all RAIDS are redundant. For instance, RAID 0 does not include copies of data on different drives and is not redundant. No matter how many drives are assimilated in it, one drive upon failing physically will affect others as well.
Myth2- RAIDs are Perfect Backups-
Many users think that RAIDs are absolute backups too, but that’s not true. If we talk about RAID 5, RAID 6 and mirrored systems, the redundancy they have can lessen the risk of losing data upon a physical failure. If multiple drives collapse at one time, a user can accidentally delete files that can lead to the corruption of RAIDs, or it becomes easy for cyber intruders to leave malicious content that can encrypt the information and your data is lost forever. Therefore, it clearly states that these devices are not backups.
However, many users firmly believe that RAIDs are super secure for data protection. Many tests conducted by the data protection experts have clearly shown how data can be easily lost, destroyed and confiscated even if the RAIDs have inbuilt redundancy.
Even the RAID data recovery always speak of purchasing the RAID and drives of same built, model, age and make for them to work correctly.
Myth3- RAIDs can Fail at any Time-
The problem with RAIDs is, even if one of the drives fail with RAID in parity or redundancy in place, the system keeps running in the debased form, working in slow speed and providing low performance. Even in the degraded form, the user can access all his data, carry on with his work and may not even notice any malfunction in the RAID until other drives collapse. To prevent it from happening, you must check your systems regularly and take professional help if you find anything suspicious.
Myth4- RAIDS do not need a Backup-
Data can be lost from your hard drives, flash drives, thumb drives, etc. and even RAIDs. Machines cannot be fully trusted with data preservation. Therefore, it is wise to have multiple copies of essential data at various locations, so even if your RAIDs fail, you have a secure copy of your data with you.
