Which component is not found in solid state drives?

Solid state drives (SSDs) utilize flash memory as their primary storage medium, which distinguishes them from traditional hard disk drives (HDDs) that rely on magnetic platters to read and write data. The inclusion of flash memory is a defining feature of SSDs, enabling faster data access speeds and improved durability since there are no moving parts.

Additionally, SSDs are equipped with a controller chip that manages the data being written to and read from the flash memory, as well as ensuring that the data is organized efficiently. This chip plays a critical role in the overall performance of the drive.

The input/output interface, which allows communication between the SSD and the computer system, is also a standard feature in SSDs, ensuring compatibility with different systems and allowing for rapid data transfer.

In contrast, magnetic platters are specific to traditional HDDs and are entirely absent in SSDs, making this component the correct answer. This difference is crucial when distinguishing between the two types of storage devices.
