Episode 86 — RAID Levels Explained — 0, 1, 5, 6, and 10
from Certified - CompTIA Cloud+ Audio Course · host Jason Edwards
In this episode, we detail Redundant Array of Independent Disks (RAID) configurations and their impact on storage performance, redundancy, and capacity. RAID 0 offers striping for speed but no fault tolerance, while RAID 1 mirrors data for redundancy at the cost of usable capacity. RAID 5 provides striping with distributed parity for balanced performance and fault tolerance, RAID 6 extends this with dual parity for higher resilience, and RAID 10 combines striping and mirroring for both performance and redundancy. Each level is explained with its operational characteristics and trade-offs.We also cover how cloud and hybrid deployments may implement RAID either at the hardware layer or via software-defined storage platforms. In the Cloud+ exam, RAID questions often require selecting the correct level for a given workload’s performance and availability requirements. Produced by BareMetalCyber.com, where you’ll find more cyber prepcasts, books, and information to strengthen your certification path.
