PHONE REPAIR GLOSSARY / LAPTOP REPAIR / SSD VS HDD
SSD vs HDD — Laptop Storage Explained
Laptop painfully slow? The most likely culprit is a spinning hard drive (HDD). Replacing it with a solid state drive (SSD) is the single most impactful upgrade for most laptops — typically cutting boot time from 90 seconds to 10.
HDD vs SSD — the core difference
- Spinning magnetic platters + read/write head
- Slow: 80–160 MB/s typical read speed
- Fragile — drops can cause instant data loss
- Generates heat and vibration
- Still found in older laptops and budget models
- Flash memory chips — no moving parts
- Fast: 500–3500 MB/s read speed
- Shock resistant — survives drops much better
- Runs cool and silent
- Standard in all modern laptops
Real-world speed difference
| Task | HDD | SSD |
|---|---|---|
| Windows boot | 60–90 seconds | 8–15 seconds |
| Opening Chrome | 5–10 seconds | 1–2 seconds |
| Opening Microsoft Word | 8–15 seconds | 1–3 seconds |
| Waking from sleep | 10–20 seconds | Instant |
How to tell if your laptop has an SSD or HDD
MacBook: Click Apple menu → About This Mac → Storage. SSDs show as Flash Storage. All MacBooks from 2013 onwards have SSDs.
Types of SSD — which does your laptop need?
| Type | Speed | Found in |
|---|---|---|
| SATA SSD | ~500 MB/s | Older laptops, replaces 2.5″ HDD directly |
| NVMe M.2 SSD | 1500–3500 MB/s | Most laptops made after 2017 |
| PCIe 4.0 NVMe | Up to 7000 MB/s | High-end gaming laptops, newer ultrabooks |
