How to configure Windows Software RAID

Published on June 8, 2023

Depending on the amount of drives you have in your system you are able to setup the following RAID sets.

RAIDPerformance/FailMinimum Drives
RAID-0 (striped)No redundancy.2
RAID-1 (mirrored)1 drive can fail.2
RAID-5 (striped with distributed parity)1 drive can fail (better performance).3

To manage our RAID sets we will need to use the Disk Management utility, you can open this by pressing the Windows key + r and type diskmgmt.msc.

This will open the following window:

The following can be found here:

1. (blue): The volumes mounted to your system

2. (green): The disks available in your system, here you see 4 2TB drives attached.

3. (purple): The volumes allocated on your drives. We have installed our system on drive 0 with a C drive of 1.8TB, the other drives are still unallocated.

RAID-0

RAID-0 combines two or more drives to increase performance and capacity but does not provide fault tolerance. A single drive failure will result in the loss of all data on the array. RAID-0 is useful for non-critical systems where a high price/performance balance is required.

RAID-0 is almost never used with the boot drive, if you want this please contact support@worldstream.nl to help you further.

RAID-1

RAID-1 is most often implemented with two drives. Data on the drives are mirrored, providing fault tolerance in case of drive failure. A single drive failure can be sustained without data loss. RAID-1 is often used when fault tolerance is key, while space and performance are not critical requirements.

RAID-5

RAID-5 provides fault tolerance and increased read performance. At least three drives are required. RAID-5 can sustain the loss of a single drive. In the event of a drive failure, data from the drive is reconstructed from parity striped across the remaining drives. As a result, both read and write performance are severely affected while a RAID-5 array is in a degraded state. RAID-5 is ideal when space and cost are more important than performance.
