For improving the performance and reliability of data storage usually, RAID is a technology in consideration. It is an Abbreviation and stands for redundant array of independent drives or redundant array of the inexpensive disk. In the system, there are two or more drives that are working in parallel. This can be hard disk as well, but in solid-state drives as well, the same is in trend. There are different RAID types, and each one is optimized for a particular situation. A user can consider these types to level as well. Let’s have a look at all of them so that implementation will become an easier task to do.
Types to know:
In the RAID 0 level, the data is split into blocks and then get written over all the drives in an array. Multiple discs are considered at the same time. Usually, two disks are in use. It offers superior performance as compared to others. With the help of multiple controllers, the performance can be enhanced easily. Ideally, per disc, one controller is required. In this, all storage capacity is used, and it is very easy to implement as well. For non-critical storage of data, this one is best to consider and easy to use as well.
With RAID 1, the data will be stored twice as it has return on both the data drive and the set of data drives. Mirror drive gets generated. If the drive fails, in any case, the controller can use the data drive or the mirror drive and get the data. It is a continuous operation. In this one, at least two drives are required. It is also a simple technology to use. For mission-critical storage, it is an ideal choice to have. For example: – the accounting systems.
It is one of the most secure RAID types. In this, three drives are required, and this can work up to 16. All the data blocks will get stripped across the drives, and parity checksum of all the block data will be written over it. In the fixed drive, the parity data is not there, and they can spread across all the drives. With the help of parity data, the computer will be able to recalculate the data that is available on other blocks as well. This clearly means that in a single drive, all the data will get withstand. It is an ideal choice to consider that combines efficient storage with excellent security and decent performance. For application and file service as well, it is an ideal choice to consider because it has a limited number of data drives.
RAID 6 is also somewhere similar to RAID 5. But the parity in this will be written to two different drives. It means that at least four drives are required, and if two drives are dying simultaneously, it can withstand the situation. The transfer of data is very fast over it, and no trouble will arise at all. It is an ideal choice to consider for efficient storage, along with security and decent performance. It is mostly considered as compared to RAID 5 because it uses many large drivers for data storage, and in case of emergency as well, no problem will arise.
It is a combination of 1 and 0. It is a hybrid configuration that is used and provides security by copying all the data on the secondary drive. It uses is stripping across each set so that the transfer of data will get speed up. It is an ideal choice to consider because the transfer time is very fast, and there is no need to copy data from the surviving mirror to the new drive. On the drive of 1TB, the data will get copied in less than 30 minutes.
Wrapping it up:
These are RAID types that a user can consider. It clearly depends on which one they are referring to. But we suggest you prefer the one shooting to your requirement. In case you have missed any specification, then problems may arise that create troubles later on.
