Top 10 Tips from Data Recovery Company When Building A RAID System


RAID or Redundant array of independent Disks was coined at UC Berkley and is a modern storage technology used to increase data reliability. The data is duplicated across a series of storage devices in a configuration also known as an array of disks. There are mainly six types of RAID array configurations known as RAID levels and each of them are denoted by a digit numeral from 0-6. If you are looking to build a RAID system, you might want to consider hiring a data recovery company to help you with it.

If you are planning to build a RAID system, here are a few useful tips that will come handy.

  • It is important to understand your requirement before you start to build a new RAID system. Ensure that you do not underestimate the capacity of RAID system that you will need and the life of the storage system. These are two important factors to consider as they will ensure that your RAID system lasts for the time period that you expect it to last.
  • When choosing the RAID level, you need to consider three factors – cost, speed and fault tolerance of the RAID system. Of the three parameters, you will need to choose two parameters.

Cheap and Fault tolerant – RAID 5 or RAID 6

Fast and Cheap – RAID 0

Fast and Fault Tolerant – RAID 1 and RAID 0

  • If you have chosen to build a RAID 0, you might also consider SSD to get value for your money.
  • If you want to be double sure that your data doesn’t get lost, it would be a good idea to add hot spares to your RAID system. If a drive in the fault tolerant array like RAID 1 and RAID 5, your system becomes vulnerable to data loss. If during this time, any other drive fails, the entire data is lost. So, by getting hot spares, you reduce your chances of data loss.
  • Considering RAID 6 instead of building a RAID 5 with a capacity of 10TB or more is more beneficial. Since increasing the capacity in RAID 5 may make it more prone to data loss, RAID 6 is much more useful at this point.
  • After building the RAID system, test the fault tolerance early enough to cause any major problem later on. Test it before you start uploading any production data into it.
  • Do not trust your RAID blindly, back up the data regularly even if they are fault tolerant. Even though the RAID is redundant to failures, there may be other failures that might need to be fixed.
  • Regularly check the RAID performance and monitor the SMART status on the drives. If you see a drop in the throughput may mean that one of your hard drives is not working properly. Check it instantly to avoid any problems in the future.
  • If there is a RAID failure, it is a good idea to send the disks to a good data recovery company to recover the lost data. It is important to trust professionals to avoid any permanent loss of the data.
