RAID 5 Explained: How Data Survives Disk Failures with XOR Parity

RAID 5 Explained: Data Protection with Math! In this video, we’ll break down how RAID 5 actually works behind the scenes. Using a simple one-megabyte file, we’ll follow the data as it’s divided into blocks, grouped into stripes, and written across three disks with XOR parity for protection. You’ll also see exactly how RAID 5 rebuilds lost data when a disk fails. We’ll cover it all: 00:00 Intro – Why RAID matters 00:28 File blocks and stripes explained 03:04 How XOR math protects data 03:27 RAID parity calculation 03:50 RAID 5 recovery after disk failure 04:15 Wrap-up – RAID 5 pros and cons Whether you’re a sysadmin, a homelab builder, or a student learning storage fundamentals, this video gives you a clear and practical explanation of RAID 5, parity math, and data recovery. 🎯 Keywords in focus: RAID 5 explained, RAID 5 parity, RAID 5 example, RAID 5 recovery, RAID 5 XOR, RAID controller explained, how RAID works, RAID storage tutorial, RAID 5 for beginners 📢 Stay Connected 🌐 Subscribe: https://youtube.com/@globaltechnologyoptions 📘 LinkedIn: https://www.linkedin.com/company/globaltechnologyoptions 📷 Instagram: https://instagram.com/globaltechnologyoptions 💬 Got questions?
