How to Choose the Right HDD/SSD for Your PC**
Choosing the right storage for your PC is just as important as choosing the CPU or RAM.
Your drive affects:
- How fast your PC boots
- How quickly apps and games load
- How smooth your workflow feels
- How long your storage lasts
- How your PC behaves under heavy tasks (editing, gaming, AI tools, etc.)
This detailed guide helps you understand exactly what type of storage you need.
1. First Step — What Do You Use Your PC For?
Different workloads need different storage types.
A) Gaming
Games need fast read speeds:
- SSD (NVMe) strongly recommended
- 1TB minimum
- NVMe improves loading speed, open-world streaming, and texture loading
B) Video Editing / Content Creation
You need:
- Fast storage (NVMe Gen 4/5) for editing
- Large capacity for storing footage
Minimum:
- OS drive: 1TB NVMe
- Project drive: 2TB NVMe
- Archive drive: 4–10TB HDD
C) AI Tools / Large Datasets
You need:
- High NVMe speed
- Very high endurance (TBW rating)
D) Office Work / Regular Use
A simple SATA SSD is enough.
E) NAS / Backup / Long-Term Storage
Use:
- Large HDD (6TB–16TB)
- 7200 RPM
- CMR technology
- Designed for 24/7 operation (WD Red, Seagate IronWolf)
2. Understanding Drive Types (Important!)
There are three main types of storage drives in 2025.
A) HDD (Hard Disk Drive) – Slow but Cheap
Best for:
- Backup
- Mass storage
- Storing large files (movies, photos, raw footage)
Advantages:
- Very cheap per TB
- Large sizes available (4TB–20TB)
Disadvantages:
- Slow boot time
- Lower durability
- Not good for gaming or editing
B) SATA SSD – Fast, Affordable, Big Upgrade Over HDD
Great for:
- Normal PC use
- Light gaming
- Older desktops and laptops
Advantages:
- 5x faster than HDD
- Affordable
- Very reliable
C) NVMe SSD (M.2) – Fastest Storage Available
Best for:
- Gaming
- Video editing
- Heavy multitasking
- AI workloads
- Professional use
Comes in two generations:
• NVMe Gen 3
Fast and cheap – good for older systems.
• NVMe Gen 4
Very fast – ideal for modern PCs.
• NVMe Gen 5 (Fastest)
Professional use only – high temps and expensive.
3. How Much Storage Do You Actually Need?
Here is the realistic recommended capacity:
| User Type | Recommended Size |
|---|---|
| Office / Home use | 500GB – 1TB SSD |
| Gaming | 1TB – 2TB NVMe |
| Video Editing | 2TB – 4TB NVMe + 4–10TB HDD |
| AI / ML | 2TB NVMe minimum |
| Professionals | 2TB+ Gen4/Gen5 NVMe |
Important:
Modern games like GTA 6, Call of Duty, and Cyberpunk can take 150–250GB each.
So, 512GB fills up VERY quickly.
4. NVMe vs SSD vs HDD — Which Should You Choose?
| Feature | HDD | SATA SSD | NVMe SSD |
|---|---|---|---|
| Boot speed | Very slow | Fast | Instant |
| Game load | Slow | Good | Excellent |
| Video editing | Poor | Good | Excellent |
| Lifespan | Moderate | High | High |
| Price per TB | Cheapest | Moderate | Highest |
| Best For | Backup | General use | Gaming/Pro use |
5. Read/Write Speeds (Simple Explanation)
HDD Speed
- 80–150 MB/s
(Slowest, causes bottlenecks)
SATA SSD Speed
- 450–550 MB/s
(Good for normal use)
NVMe Gen 3
- 1500–3500 MB/s
NVMe Gen 4
- 5000–7500 MB/s
NVMe Gen 5
- 10,000–14,000+ MB/s
(Needs heatsinks, high temps)
6. Endurance Rating (TBW / DWPD) — Important for Longevity
Endurance (TBW) = How much data you can write before the drive wears out.
- Light use → 100–300 TBW
- Gaming → 300–600 TBW
- Editing / AI → 1000+ TBW
Higher TBW = longer-lasting drive.
7. Choosing Based on Use Case
✔ Best for Gaming
- NVMe Gen 4 SSD
- 1TB or 2TB
Examples: - Samsung 980 Pro/990 Pro
- WD SN850X
- Kingston KC3000
✔ Best for Video Editing
- Large NVMe + HDD combo
- 2TB NVMe + 4TB HDD
Examples: - Samsung 990 Pro
- WD Black SN850X
- Seagate Barracuda HDD
✔ Best for NAS / Backup
Use 7200 RPM CMR HDD:
- Seagate IronWolf
- WD Red Plus
- Toshiba N300
✔ Best for Office Use
- 500GB or 1TB SATA SSD
Examples: - Crucial MX500
- Samsung 870 EVO
8. Common Storage Mistakes to Avoid
❌ Buying only HDD for main system
→ PC will feel VERY slow
❌ Buying too small SSD (500GB fills instantly)
❌ Using QLC SSD for gaming/editing
→ Slower long-term performance
❌ Not checking motherboard for M.2 slots
❌ Buying NVMe without heatsink (Gen 4/5 run hot)
9. Future-Proofing Your Storage
To ensure your storage lasts 4–6 years:
✓ At least 1TB SSD (preferably NVMe)
✓ Gen 4 speed (7000 MB/s+)
✓ High TBW endurance
✓ Large HDD for backup
✓ Use UPS to prevent power-related damage
10. Final Recommendation
If you want something simple:
- Budget → 500GB SATA SSD
- Best for gaming → 1TB NVMe Gen 4
- Best for creators → 2TB NVMe Gen 4
- Best for backup → 4TB+ HDD
- Best overall combo → 1TB NVMe + 4TB HDD
