Dec 23, 2025 · Fault Tolerance: If one drive fails, RAID uses the redundant data (mirror or parity) to reconstruct missing data. RAID 1 gives you drive-level fault tolerance, but only half of raw capacity with two drives. When setting up a server, I was told it needs to have really good fault tolerance. What happens if I accidentally remove a drive from the RAID array? This one design difference drives everything else: RAID 0 gives you more speed and full combined capacity, but zero fault tolerance. By distributing data across disks, RAID can improve performance, increase usable capacity, and—most importantly—provide protection against disk failures.
