What type of storage drive is most likely to be replaced by an M.2 Solid State Drive?

The correct answer highlights that an M.2 Solid State Drive is most likely to replace a 2.5 inch or 3.5 inch storage drive. This is because M.2 SSDs are designed to provide a compact and high-speed storage solution, typically used in systems that have traditionally utilized these larger drive formats.

M.2 drives connect directly to the motherboard via the M.2 interface, which allows for significantly faster data transfer speeds compared to traditional spinning hard disk drives (HDDs). The reduction in physical size, combined with their enhanced performance, makes M.2 SSDs an appealing replacement for the 2.5 inch and 3.5 inch drives commonly found in laptops and desktops.

In contrast, devices like flash drives, SD cards, and external hard drives serve different purposes and are usually used as portable storage solutions rather than direct replacements for internal storage drives in computer systems. Thus, they are less likely candidates to be replaced specifically by M.2 SSDs, as their roles and use cases differ.
