Question

A company is encountering slow write performance on its RAID 6 array.

What is the most likely reason for this performance bottleneck?

A Write penalty associated with dual parity calculations
B Insufficient storage on the RAID controller
C High read I/O load on the array
D Increased network latency between the server and the storage array

Explanation

RAID 6 writes incur a dual-parity write penalty because data updates require calculating and writing two parity blocks, often along with read-modify-write operations. This additional work reduces write performance.
