Most tablets and phones use ________ as their main storage device.

HDD

SSD

Tablets and phones use solid-state flash storage as their main storage. This non-volatile memory stores the OS, apps, and data without needing power to retain information, and it has no moving parts, making it fast, durable, and power-efficient for mobile devices. That’s why the best choice is solid-state storage (SSD). Hard disk drives rely on spinning disks and are bulky and fragile for mobile use, while RAM is temporary working memory and USB drives are external, not the device’s built-in storage.
