08. Storage Hierarchy & RAID Systems | CSE 3103 - Database Theory

Understand how databases store data physically! Explore the storage hierarchy from volatile cache and RAM to non-volatile secondary and tertiary storage. Deep dive into RAID (Redundant Array of Independent Disks) systems - learn about RAID 0 (striping), RAID 1 (mirroring), and RAID 2. Compare software vs hardware RAID implementations and understand MTBF (Mean Time Between Failures). Includes practical capacity calculations!

🎯 Topics Covered:

Storage Classification (Volatile/Non-volatile)
Primary, Secondary & Tertiary Storage
RAID Fundamentals
RAID Level 0 (Striping)
RAID Level 1 (Mirroring)
RAID Level 2 (ECC)
Software vs Hardware RAID
Storage Capacity Calculations
