The biggest performance boost in computer upgrades comes from an SSD. Switching from an old HDD to an SSD makes the system feel reborn. However, terms like NVMe, SATA, PCIe generations, and DRAM cache can be confusing.
In this guide, we explain everything you need to know when buying an SSD in 2026.
SSD Types
SATA SSD
Info
Ideal for older systems. 2.5" form factor, 550 MB/s maximum speed. A big upgrade from HDD but slower than NVMe.
- Compatible with all systems
- Affordable price
- 550 MB/s speed limit
- Requires cables
NVMe SSD (M.2)
- 7000+ MB/s speed (PCIe 4.0)
- Compact M.2 form factor
- Cable-free installation
- Requires compatible motherboard
- Heating issue (heatsink recommended)
PCIe Generations
| PCIe | Max Speed | Availability |
|---|---|---|
| PCIe 3.0 | ~3500 MB/s | Older systems |
| PCIe 4.0 | ~7500 MB/s | Current standard |
| PCIe 5.0 | ~14000 MB/s | Next-gen, expensive |
What to Consider When Choosing an SSD
Capacity Recommendations
| Capacity | Use |
|---|---|
| 250-500GB | Operating system only |
| 1TB | Daily use, a few games |
| 2TB | Gaming, content creation |
| 4TB+ | Professional, video editing |
Tip
Recommendation: Get at least 1TB in 2026. Games take up 100GB+ and SSD prices have dropped.
Why is DRAM Cache Important?
DRAM-less SSDs:
- Low price advantage
- Slowdown during extended writes
- Not suitable as boot drive
SSDs with DRAM:
- Consistent performance
- Longer lifespan
- Ideal for system drive

Frequently Asked Questions
Is the difference between NVMe and SATA noticeable?
In daily use (boot, app launching) the difference is small. NVMe makes a noticeable difference in large file transfers and game loading.
Does a PCIe 4.0 SSD work in a PCIe 3.0 slot?
Yes, it's backward compatible. However, it runs at PCIe 3.0 speed (3500 MB/s).
How long does an SSD last?
Modern SSDs easily last 5-10 years. The TBW value means 10+ years of life at 50-100GB daily writes.
Is a heatsink necessary?
PCIe 4.0/5.0 SSDs can get hot. Heatsink is recommended for continuous heavy workloads (video rendering). Not essential for daily use.
Which SSD should I get for PS5?
PCIe 4.0, 5500 MB/s+ speed, with heatsink. Samsung 990 Pro or WD SN850X are ideal.
Conclusion
In 2026, the best SSD choice depends on budget and use case.
