vRAID Level 1 – Mirrored disk array

Two hard disk drives minimum

Improved read performance and 100% redundancy

vRAID Level 5 – Block-level striped disk array with distributed parity

Three hard disk drives minimum

Data striped at the byte level

Stripe error correction information

Better performance and fault tolerance

vRAID Level 10 – Combining features of RAID 0 and RAID 1

Four hard disk drives minimum

Very high reliability combined with high performance
