FINAL BRIEFING

RAID Levels — Head to Head

LEVEL	TECHNIQUE	MIN DISKS	SURVIVES	CAPACITY	4×HDD SPEED (R/W)
RAID 0	Striping	2	0 disks	100%	~800 / 800 MB/s
RAID 1	Mirroring	2	1 disk	50%	~400 / 200 MB/s (2 disks)
RAID 5	Stripe + 1 Parity	3	1 disk	(n−1)/n	~720 / 360 MB/s
RAID 6	Stripe + 2 Parity	4	2 disks	(n−2)/n	~720 / 200 MB/s
RAID 10	Mirror + Stripe	4	1 / pair	50%	~720 / 400 MB/s

Speeds assume ~200 MB/s SATA HDDs. RAID is not a backup — it protects against disk failure, not deletion, ransomware or fire.
