Which of the following influences the reliability of recovered digital data?

The reliability of recovered digital data is significantly influenced by both the type of storage device and the technician's training. Different types of storage devices, such as SSDs (Solid State Drives) and HDDs (Hard Disk Drives), operate on distinct technologies that affect how data is stored and retrieved. For instance, SSDs utilize flash memory and can perform wear leveling and garbage collection, which may result in data being overwritten more quickly than on a traditional hard drive, impacting recovery efforts.

Furthermore, the training of the technician plays a crucial role in the data recovery process. A well-trained technician possesses the skills and knowledge needed to use the appropriate tools and techniques to maximize the chances of successful data recovery. They understand the complexities of digital forensics, such as how to handle various storage devices correctly, avoid further data loss, and apply best practices in the recovery process.

While the amount of time since deletion can affect data recovery, it is not as definitive as the influence of the storage device type and the technician’s expertise. This is why the correct answer encompasses both the type of storage device and the technician's training, as they are key elements in ensuring the reliability of recovered digital data.
