Is RAID Really Necessary to You?

Maybe you have heard a lot of discussions about the advantages of RAID, so you are sorely tempted by it. However, is it really necessary for you to invest in RAID? In this article, we will look at this question and help you make a decision.

As we all know, RAID is an advanced data storage technology. Not only can it offer users better performance, but also its data redundancy can reduce the likelihood of data losses. Hence, more and more businesses and individuals start to invest in it. Perhaps you have searched a lot about it and have made clear its pros and cons. Nevertheless, in prior to using it, you may wonder whether it is exactly necessary to you. If you indeed have this consideration, please read on. Here we’ll discuss about it and help you get the answer.

Is RAID Really Necessary to You?

It Depends

In honesty, whether RAID is essential for you depends on many factors, including your own requirements of disk storage and speed, data backup as well as if you have some basis knowledge about RAID.

1. Storage Space

Unquestionably, one of the most attractive RAID’s advantages that it can combine several physical drives into a single logical unit. Therefore, you can achieve more storage space simply by adding the additional drives. From this perspective, you need to consider if you have a large requirement for storage space. If you are only a common home user and an individual drive with 1.5 TB or so is enough for you, it is actually not necessary to you to use RAID.

2. Performance

Apart from storage, the next thing worthy of mentioning in terms of RAID is its better performance, namely faster read/write speed. If you are a game enthusiast, you can think of using RAID 0, by which you can experience the most quick speed contrast to other RAID levels. But, if you’re only a user that copes with some files, without constant and frequent deals with big data, it’s suggested not to use RAID.

3. Data Backup

Moreover, RAID earns a lot of kudos due to data redundancy and fault tolerance. It refers to that when a disk fails, the RAID system still can keep running without data losses, like damaged PST. Yet, as per my previous article – “Why You Should Never Use RAID as a Backup Solution?“, data redundancy is not equal to data backup. You still have to back up RAID data regularly. Also, it is more complex to back up RAID. So, if you simply hope to treat data redundancy as backup, please dispel the idea of RAID right now.

4. Basic Knowledge

Last but not least, using RAID is much more complicated than using a single hard drive. Thereby, it demands that you must have some basic knowledge about RAID. For example, in case of RAID failures, what should you do, or how can you set up RAID correctly and so on. Provided that you’re totally a novice in this field, you’d better not use RAID. In contract, if you are a senior in IT, you can have a try.
