Why Raid 1 has still may be a better option than a Raid 5 System


Raid 5 may have more disks in order to spread sensitive data and protect it from hackers and other data malfunctions, but Raid 1 may be a better option. Did you know that by going from three disks to four, you may be doubling your opportunity for data loss and increase the need for data loss recovery from an expert?


Flaky disks may have a 10 percent chance of failure, however if two disks are placed in a Raid 1 system, the chance for failure are still 1 percent. However, if three of those disks are used in a Raid 5 array, the chances for failure increase 2.8 percent. If you have a flaky disk, this raises the chances of failure by 5.23 percent.


Raid 1 is less risky, but Raid 6 is more reliable than a Raid 5 system


Raid 1 is less risky than not using a disk at all to store backup data. With every Raid system, there is an opportunity for failure. Why is Raid 6 better than a Raid 5 system? It is best to run a consistency check and run backups. Raid 6 has a high fault tolerance and allows ...
... for multiple disk failures. Since there are more drives, Raid 6 may be better than a Raid 5 system. Raid 6 is a better option that for companies that have need a large capacity to protect sensitive data.


If you need to encode data, Raid 6 is also a better option. It does require a more complex system though. Businesses must have faster hardware or their performance will suffer. This is not necessarily the case with a Raid 5 system. Raid 6 improves uptime from a Raid 5 system. This is why it may be better for some businesses to opt for a Raid 5 system over a Raid 6 system. Raid 6 lessens the chances of data loss from drive failure. However, this may not convince all businesses to switch from a Raid 6 to a Raid 5 system. It may be better to use Raid 6.


Raid 6 definitely has an advantage over Raid 1, but either Raid 1 or Raid 6 has advantages over a Raid 5 system. Should a business choose a Raid 1 or Raid 6 system? It may depend on business or individual needs. Does cost or encoding matter when choosing a system which backs up your sensitive data and allows you to write and read data easily? Is the fact that a Raid 6 needs encoding a reason to switch to another type of Raid system, such as a Raid 1 system?
