Which two types of storage contain persistent data that can assist computer forensics specialists?

Choosing hard disk drives and solid state drives as the correct answer reflects an understanding of how persistent data is stored and retained on devices commonly used in computers.

Hard disk drives (HDDs) utilize magnetic storage to hold data on rotating platters, allowing for long-term retention of files even when the power is turned off. This persistent data can include everything from the operating system to user files and system logs, all of which can be crucial for forensic investigations.

Similarly, solid state drives (SSDs) store data in flash memory chips, making them faster than traditional HDDs. Although SSDs have a different storage mechanism, they also retain data without power, making them reliable sources of persistent information for forensics. The data carved from these drives can include deleted files, browser history, and other user activity logs, making them integral in forensic analysis.

Other options listed contain storage types, such as USB drives, floppy disks, cloud storage, and optical disks, which may not consistently meet the same criteria for persistent data or may not be as widely utilized in contemporary forensic investigations compared to HDDs and SSDs. Although some of these can also hold persistent data, their uses and relevance in forensic contexts might differ significantly from those of traditional and modern hard drives
