Enjoy faster performance and better failover with a RAID server configuration.
RAID, or Redundant Array of Independent Disks, combines multiple physical disks into a single disk for faster performance, better hardware failover, and improved disk Input/Output reliability.
Whether or not your server needs RAID depends on how critical uptime is to your services.
Unfortunately, all hard drives fail, it's just a matter of when. With RAID in place, the drive would be replaced, and you could rebuild and sync the RAID from the old drive to the new drive, and there would also be no backup restoration needed. Without RAID, your server and business will suffer downtime while the drive is being reconfigured and replaced. Then you must wait for the backups to be restored. This process could take 5 hours or more.
Further complications can arise without RAID. You may miss some modules when rebuilding the data, drive, and system. Functionality with your website can face issues after data restoration. There may also be a loss of data.
If staying online is essential, consider RAID your failover insurance.
Not all RAID configurations are created equal in terms of redundancy, speed, or disk size. The most common RAID levels are RAID 0, RAID 1, RAID 5, RAID 10.
RAID 0: This level uses striping to spread your data blocks across drives in the RAID array. Striping combines several disk drives into a single volume. While this increases I/O performance, there is no redundancy, so it is not recommended for use on critical systems.
RAID 1: This level uses mirroring to store your data on separate drives. Disk mirroring replicates data to two or more disks. While this configuration offers redundancy and can stay online if an array uses a drive, it does not have great I/O performance because it lacks striping.
RAID 5: The difference between RAID 1 and RAID 5 is RAID 5 offers an improvement in performance because the blocks are striped. This level offers fault tolerance with parity that allows for data rebuild in the event of a drive failure.
RAID 10: This configuration is the best option for critical applications, especially databases, because the blocks are mirrored AND striped. This is also referred to as RAID 1+0 because it combines the I/O benefits of RAID 0 with the hardware failure protection of RAID 1.

HostDime techs created a RAID calculator that compares and configures RAID options and drive sizes to expand on your server’s performance.
Simply drag and drop the drives into the slots to see each RAID’s description, disk capacity, disk I/O performance, minimum number of disks, and fault tolerance.
RAID options are available with the purchase of any HostDime dedicated server. Servers are fully customizable during the order process to add a variety of RAID options to increase performance.
Choose the server that best fits your needs below, and then you will be able to choose your RAID server options.
