312-49V11: Computer Hacking Forensic InvestigatorDemo

Question

During a large-scale healthcare breach in Boston, forensic investigators must archive several terabytes of compromised patient records for long-term preservation of evidence. Because the data will be written once as forensic images and accessed infrequently, analysts need the storage technology that provides maximum capacity at lower cost, even if endurance and performance are reduced. Which type of NAND flash memory in the seized SSD best satisfies this forensic requirement?

A Quad-level cell (QLC)
B Multi-level cell (MLC)
C Single-level cell (SLC)
D Triple-level cell (TLC)

Explanation

Quad-level cell (QLC) NAND stores four bits per cell, providing the highest density and a lower cost per GB than SLC, MLC, or TLC. The added bit density reduces endurance and NAND-level performance, which suits infrequently accessed, write-once archival evidence.
