RAID stands for Redundant Arrays of Independent Disks. This storage option is used with multiple different versions like raid 0, raid 1, raid 2, raid 3, raid 4, raid 5, raid 6 and raid 10. All those versions provide different benefits to users. Such as raid 0 is great for storing data in two drives but if any of them is failed you lose all data. Therefore, if you use the combo of raid 1 and raid 0 you get the option that all your data can be restored.
However, all the raids are different from each other but the basic functionality is the same. On most of the raids, you’re going to get the improvement in Reed and write speed with the data recovery option. In this post, you’re going to get the full information of raid 5 and raid 6 with all the deference.
What is Raid 5?
Raid 5 has block-level data distribution with three different drives. In simple words, it’s partly to save your data on different drives. If you’re using raid 5 your data is safe in case one of your drives stops working.
Raid 5 also provides good Read and write speeds. It’s the same as raid 0 in terms of speed and performance. It’s considered one of the safest raids out there.
What is Raid 6?
Raid 6 uses block-level striping with double-distributed parity across all drives. It can easily tolerate two drive failures at the same time. It takes four or more disks to work smoothly, which is why it becomes a most expensive raid than other raid configurations with the high data security.
The bad thing about raid 6 is that the write speed is comparatively lower than other raids and the data recovery process takes a longer time than other raids.
RAID 5 vs RAID 6
Raid 5 and raid 6 are pretty similar to each other’s configurations. However, there are still some differences like raid 5 provides much more speed and performance than raid 6. It also has a good data security system but it cannot handle two drive failures at the same time although it’s cheaper than raid 6 because it needs 3 drives to work smoothly.
On the other hand, raid 6 is expensive because it requires 4 drives to work without any problem. It also handles two drive failures at the same time but it cannot compete with raid 5 speed and performance. If you have high usage then raid 6 is best for you because of its data security and recovery option.
RAID 5 VS RAID 6: Performance
Everyone wants to save time which is why performance is an essential part of any technology. Raids provide high security plus the data is much more secure than other methods. But the performance of any storage system is calculated by the reads and write speed of that storage system.
We already discussed the overall performance difference between both raids Same as that raid 6 has much more security than raid 5 but it didn’t have as much speed as raid 5. In simple words raid 5 is the winner in terms of the read and write speed of Disks.
RAID 5 VS RAID 6: Data Security
Raids are used for increasing the overall performance and security of data. Raid 5 provides you with this functionality, If one of your drives fails then the two drives are ready for you to store your data. So, you don’t have to worry about losing your important files.
Although, if your two drives failed raid 5 can’t recover your data. But, if you’re using raid 6 it can be possible because raid 6 can tolerate two drive failures simultaneously. Hence, it used four drives to create that configuration. The only downside of raid 6 is it cannot compete with raid 5 in terms of speed.
RAID 5 VS RAID 6: Practice Usage
Raid 5 and raid 6 both have different advantages and disadvantages so it’s up to you which one you want to use but it mostly depends on your usage. Raid 5 is used where people want good speed with basic security like data Warehouse, web serving, and more things.
However, raid 6 is used by people who want high security and required high storage. You can use raid 6 instead of raid 5 but you cannot do this and vice versa. Make sure you choose the right raid because raid 6 can save your data on two drive failures but raids 5 can’t.
RAID 5 VS RAID 6: Capacity Utilisation
If your drive capacity utilization is higher than the storage is higher in your drives. Therefore, it’s important to know the capacity of the drive utilisation before creating raids whether it’s raid 5 or raid 6.
If you go with raid 5 it can provide you with a capacity between 57 percent to 97 percent it also depends on other factors as well. However, raid 6 can give you between 50 percent to 88 percent. So the clear winner in captivity utilisation is raid 5.
RAID 5 VS RAID 6: Software Or Hardware RAID
There are two types of raid software and hardware base. The software raid required the hardware raid to work properly but the hardware raid didn’t require anything. You can set up raid 5 with software and hardware as per your choice. While you need hardware to create a raid 6 array.
