RAID 5 setups allow for getting the most storage out of an array of disks without loosing parity, or redundancy. For example.
Raid 5 array with four disks will have the capacity of three of those disks using the forth's pool of storage (over all the disks) as a parity bit so if one of the disks were to fail you would simply swap out the defective disk and the array will rebuild itself in an ideal world.
Because of this write speeds on RAID 5 arrays tend to be a bit slower then other arrays because it's spreading out it's data on however many disks you have any it's writing parity bits at the same time. Read speeds tend to be quick on RAID 5 making it ideal for archival use or data that must be read a lot but not edited much or changed. Think of a server dishing up programs to users or storing their finished work files.
Hope that helps!

RAID 5
The best RAID configuration depends on your specific needs for performance, redundancy, and storage capacity. RAID 1 offers excellent redundancy by mirroring data across two drives, making it ideal for critical data protection. RAID 5 balances performance, redundancy, and efficient storage use by distributing data and parity across three or more drives. For maximum performance with some redundancy, RAID 10 combines the benefits of RAID 0 and RAID 1 but requires a minimum of four drives.
RAID 1, RAID 1 + 0, and RAID 5, 6.
Essentially that just means understanding what raid one and raid 5 are. Raid one stores the data on 2 hard disks, raid 5 stores the data on 3 to 5 disks. In either of these circumstances all the hard disks must be completely identical right down to brand cache, size etc.
For Raid 5 all the hard drives have to be of the same speed.
RAID (Redundant Array of Independent Disks) partitioning typically features data redundancy, improved performance, and fault tolerance. It combines multiple physical disks into a single logical unit, allowing for data to be distributed across drives for enhanced read/write speeds. Depending on the RAID level (such as RAID 0, RAID 1, RAID 5, etc.), it can provide varying degrees of data protection and performance benefits. Additionally, RAID configurations can often be managed through hardware or software solutions, allowing for flexibility in deployment.

Every RAID level stripes data across multiple drives, which improves performance compared to using a single disk. RAID 0, RAID 1, RAID 1+0, RAID 5, RAID 6, etc. all have better performance than a single disk. Other than RAID 0, all other RAID levels provide fault tolerance. RAID 1, RAID 1+0, RAID 5, RAID 6, etc. all have fault tolerance.
RAID controllers have a wide variety of benefits which apply to the cloud computing community. RAID essentially improves performance for programmers that need to compute various codes.
RAID 1, RAID 0+1, RAID 5 and 6.
