Which storage device is commonly used as main storage for tablets and phones?

• A. HDD
• B. SSD
• C. CD-ROM
• D. Flash Drive

Answer: (B)

Main concept: mobile devices rely on solid-state flash storage for their internal memory because it’s fast, compact, and durable. Without any moving parts, it’s lighter and more shock-resistant, which matters for phones and tablets that are often carried around. The fast access times of flash storage mean quicker boot-ups and snappier app launches, contributing to smooth multitasking while sipping less power from the battery. Hard disk drives use spinning disks and moving read/write heads, so they’re larger, heavier, slower for random access, and more power-hungry—none of which suits the lightweight, compact design of tablets and phones. Optical CD-ROMs are bulky and much slower, and they’re not designed to store and run the system and apps. Removable flash drives are external, not integrated as the device’s main storage, so they don’t provide the same seamless, fast internal access. So the storage type that best fits as main storage in tablets and phones is solid-state flash storage.
