What has non-moving parts, is a smaller form factor, and utilizes non-volatile memory?

The answer is Solid State Drives (SSDs), which are known for their non-moving parts and smaller form factor. Unlike traditional Hard Disk Drives (HDDs) that rely on spinning disks and moving read/write heads, SSDs use flash memory to store data, allowing for faster access speeds and greater durability. Since SSDs utilize non-volatile memory, they retain data even when there is no power supply, making them an ideal choice for portable devices and systems requiring quick data access.

In contrast, while flash drives also use non-volatile memory and lack moving parts, they are typically smaller and used for portable data storage rather than as primary drives in systems where performance is crucial. Hard disk drives and optical drives, on the other hand, both have moving components that can impede performance and are generally larger and less efficient compared to SSDs.

Thus, SSDs stand out in their category for offering a combination of speed, durability, and form factor that meets modern storage needs.
