What is the key advantage of RAID 6 compared to RAID 5?

Question

Options

• AHigh available storage capacity.
• BLow write penalty.
• CHigh resiliency.
• DLow rebuild time for data.

• A
  16% (8)
• B
  4% (2)
• C
  73% (37)
• D
  8% (4)

Explanation

RAID 6 can tolerate the failure of two disks without data loss, while RAID 5 can only tolerate the failure of a single disk. This makes RAID 6 a better choice for environments where data protection is critical, such as enterprise servers and data centers. RAID 6 stores two parity stripes, which means that it can still calculate the original data even if two disks fail. RAID 5 only stores a single parity stripe, so if two disks fail, the data is lost.
