Tech+ Lesson

Volatile vs non-volatile (e.g., RAM vs storage drive) for Tech+

Last updated: 6/10/2026

Short answer

Volatile vs non-volatile (e.g., RAM vs storage drive). Various storage types can be compared by volatility, access speed, and purpose: - Volatile vs Non-volatile: Volatile storage (RAM) loses data when power is off. Non-volatile storage (HDD, SSD) retains data. - Local storage: - RAM: Volatile; very fast; working memory for running programs. - ROM: Non-volatile; stores firmware; not writable under normal operation. - HDD: Magnetic disks with moving parts. High capacity, moderate speed. - SSD: Flash memory, no moving parts. Much faster than HDD. NVMe SSDs use PCIe for very high speed.

Why it appears on the exam

This lesson supports FC0-U71 2.0 on CompTIA Tech+ FC0-U71. The public page gives the basic concept for free; the app adds tracking, quizzes, and weak-area practice.

Key concepts

Concept 1

Volatile vs non-volatile (e.g., RAM vs storage drive)

Volatile vs non-volatile (e.g., RAM vs storage drive). Various storage types can be compared by volatility, access speed, and purpose: - Volatile vs Non-volatile: Volatile storage (RAM) loses data when power is off. Non-volatile storage (HDD, SSD) retains data. - Local storage: - RAM: Volatile; very fast; working memory for running programs. - ROM: Non-volatile; stores firmware; not writable under normal operation. - HDD: Magnetic disks with moving parts. High capacity, moderate speed. - SSD: Flash memory, no moving parts. Much faster than HDD. NVMe SSDs use PCIe for very high speed. - Optical Discs: DVD, Blu-ray. Removable media, slower access. - Flash Drives: Portable flash memory (USB sticks, SD cards). Convenient for data transfer.

Terms to recognize

Recognize these Tech+ terms in simple scenarios: Volatile vs non-volatile (e.g., RAM vs storage drive), storage types, Volatile vs Non-volatile, Local storage, RAM, ROM, HDD, SSD.

Concept 3

How to recognize it on Tech+

On FC0-U71, stay at beginner IT depth: identify when the question is asking about Volatile vs non-volatile (e.g., RAM vs storage drive), then choose the basic concept or support action that matches the situation. Do not jump into advanced vendor administration unless the prompt clearly gives that scope.
