What is a RAID?
Redundant Array of Independent Disks (RAID) is often either a software- or hardware-based system that allows users to take multiple disks and use them as one device. The RAID can be configured in multiple ways, allowing for either greater data redundancy or performance.
This configuration is commonly referred to as a RAID level. The different types of RAID levels provide different functionality to get a better idea of the RAID levels. Let's explore a few that are commonly used.
RAID 0 – striping
RAID 0 is one of the simplest RAID levels to understand. The way RAID 0 works is by taking multiple disks and combining them to act as one. When data is written to the RAID device, the data is split and parts are written on each disk. To understand this better, let's put together a simple scenario.
If we had a simple RAID 0 device that consisted of five 500 GB drives, our RAID device would be the size of all the five drives together—2500 GB or 2.5 TB. If we were to write a 50 MB file...
