What type of problems can improper power supply lead to in storage devices?

Improper power supply can significantly impact the functionality and reliability of storage devices, primarily by causing insufficient power, which may lead to operational failures. Storage devices, such as hard drives and solid-state drives, require stable and adequate power levels to function properly. When these devices do not receive enough power, they may experience issues like failure to initialize or to operate correctly, which can result in data loss or corruption. This situation can also lead to unexpected shutdowns or read/write errors during operations, making the integrity of the data stored at risk.

The other options suggest positive outcomes, such as increased speeds or enhanced performance, which are not associated with power supply issues. Inadequate power can hardly lead to improved metrics or capacities; rather, it directly jeopardizes the operational integrity of the storage devices.
