All of our hosting products and services employ RAID storage. And that’s one of the most prominent features that we are extremely proud of. Our customers really appreciate the fact that we offer RAID storage with all of our hosting options.
But quite often, we come across someone or the other who uses the services of a different web hosting provider but has no clue about the type of storage their hosting provider offer. When we mention that with MyResellerHome’s hosting services, you get the industry-standard RAID storage, they are completely unfaced. And that is when I realized that most people who use the services of other web hosting providers are not quite aware of what is RAID storage, let alone RAID levels.
That is why today, we have decided to provide our readers with a complete guide to understanding RAID storage, RAID levels, RAID array types, and everything there is to know about RAID arrays.
So let us begin with an in-depth understanding of RAID storage and RAID levels and types.
RAID storage is a type of data storage system that lets multiple disks work together to make an array that is faster and more reliable than any single disk could be on its own. RAID is usually used on servers and desktop computers to increase the total amount of storage space, speed up data storage, and make sure it is safe.
The term RAID stands for Redundant Array of Independent Disks. The main advantage of using RAID is that it makes it faster to access large amounts of data. In addition, by spreading the load across multiple storage drives, you can make it easier to get to your data and ensure it will still be there if one of the drives fails.
Hardware RAID is a technology that allows multiple storage drives to be configured as a single virtual hard drive.
Software RAID is a type of RAID that uses software to manage the drives.
There are several distinctions between Software RAID vs. Hardware RAID.
RAID levels are classified into the following groups:
You may also pick how to set up RAID on your machine. As a result, you have the option of using hardware or software RAID.
But for this article, we’ll focus on RAID levels 0 to 6.
RAID 0 Stripping is a way to improve the performance of a RAID array by making the individual disks in the array into smaller, easier-to-manage volumes. When used with the right software, this method can give you much better performance than a traditional RAID setup. However, it’s important to know that you shouldn’t use RAID 0 Stripping for data that is important to your business or to store user data files. This kind of striping should only be used for short-term storage or as part of a place to try out new ideas.
When RAID 0 striping is used with software that can monitor and manage the array and give real-time feedback on its performance, it works best.
RAID 1 provides the simplest and most common form of mirroring – two hard drives are mounted as one logical drive and written simultaneously. To create a RAID 1 mirror, both hard drives must be of equal size and have the same drive letter. Once created, a mirrored drive can be used just like any other drive on your computer.
One benefit of using RAID 1 mirrors is that data is always available if either hard drive fails. If one hard drive in a RAID 1 fails, the remaining hard drive becomes the new active disk, and the failed disk is replaced with a spare.
RAID 2 is a storage technology that uses two or more disks to provide increased data protection. It provides the same level of data protection as RAID 5 but without the added bandwidth requirements. The striped sets are divided into blocks of 2048 bytes each and written to each disk in sequence. If one disk fails, the missing blocks are reconstructed from the remaining streams on the other disks. This process can be repeated until all required blocks have been recovered.
RAID 4 is a popular RAID level that uses block-level striping and dedicated parity planes.
There are many reasons to use RAID 4. First of all, it improves performance significantly compared to other RAID levels. Also, RAID 4 can protect against the loss of individual drives, which is especially important in large organizations where drives can become scarce. Even though there are some problems with RAID 4, like the fact that it needs more hardware resources, the pros usually outweigh the cons.
RAID 5 is a data protection scheme that uses parity to achieve the desired level of data redundancy. Parity information is created by adding together the bytes of the two sets of data. If any bit in the parity byte changes, then the entire byte must be recalculated and re-written to the disk. This process is repeated for allocating parity blocks until all data has been protected with parity. As a result, RAID 5 can provide up to 4 times the protection of a single disk drive.
RAID 6 is a RAID 5 array with the addition of the double parity functionality. As a result, it is also known as the double-parity RAID.
Striping with Double Parity is a popular method of improving the performance of RAID 6 arrays. When data is striped, the data is divided into two equal pieces and then written to different disks. This improves performance because it eliminates the need to search for and read data from multiple disks.
Nested (Hybrid) RAID is a RAID storage configuration in which multiple hard drives are used to build a single logical drive.
To summarize, understanding RAID storage may be difficult, but with the aid of this guide, you will be able to get a thorough grasp of what RAID levels and kinds exist, as well as how they function. You’ll be able to make informed selections regarding which RAID setup is appropriate for your requirements from now on. So, whether you want to increase your data security or just have access to your information no matter what occurs, knowing RAID storage is critical.
