HPE Converged Storage Solutions — Question 67

Which SSD controller component is responsible for wear leveling?

Answer options

• A. DRAM
• B. Processor
• C. NAND memory controller
• D. SATA interface chip

Correct answer: C

Explanation

The NAND memory controller is specifically designed to perform wear leveling, ensuring that write and erase cycles are evenly distributed across the memory cells to extend the lifespan of the SSD. The DRAM and Processor are involved in data handling and processing but do not manage wear leveling directly, while the SATA interface chip is responsible for communication between the SSD and the host system, not wear leveling.
