Which statement about SSD is correct?

• A. A completely electronic alternative to a hard drive that is faster and smaller, but more expensive
• B. It uses magnetic spinning platters
• C. It is always external over USB
• D. It cannot be used in laptops

Answer: (A)

SSDs are storage devices that use flash memory, making them electronic with no moving parts. Because there are no spinning platters, they access data much faster and can be built smaller, which is why they’re quicker and more compact than traditional hard drives. That speed and size come with a higher price per gigabyte, which matches the statement describing an entirely electronic alternative that is faster and smaller but more expensive. In contrast, the other statements aren’t accurate: SSDs don’t rely on magnetic spinning platters; they aren’t required to be external via USB (they can be internal or external); and they can be used in laptops, desktops, and other devices.
