Storage types explained — HDD, SSD, and NVMe differences and when to use each
HDD is the slow, cheap option for backup storage. SSD is fast and affordable for everyday computers. NVMe is the fastest modern option.
Three types of storage exist: HDD (mechanical hard drives with spinning platters), SSD (solid-state drives using SATA interface), and NVMe (solid-state drives using the faster PCIe interface). HDD is cheapest per gigabyte but slowest. SSD is faster and reliable. NVMe is the fastest and what modern computers use.

Common mistakes to avoid
- Buying HDD for a new laptop to save money — the performance impact on boot time and app launches makes the computer feel slow
- Assuming all M.2 drives are NVMe — M.2 is just physical size. It can be SATA (slower) or NVMe (faster). Always check the spec.
- Thinking you should wait for NVMe prices to drop — SATA SSD and NVMe are similarly priced now. Get NVMe.
Signs you need professional help
- You need to check if your specific laptop supports NVMe or just SATA SSD
- You're upgrading your computer's storage and want guidance on compatibility and installation
