PCIe Gen 5 SSDs offer 2x the speed of Gen 4 drives (14GB/s vs 7GB/s theoretical). As of 2026, Gen 5 is becoming available in premium laptops. This guide covers compatibility, performance gains, and upgrade decisions.
PCIe Generation Speed Comparison
| Standard | Max Speed | Real-World Performance | Common In |
| PCIe Gen 3 | ~4GB/s | 3.5-4GB/s | Pre-2021 laptops |
| PCIe Gen 4 | ~7.5GB/s | 6.5-7.5GB/s | 2021-2024 laptops (most current) |
| PCIe Gen 5 | ~15GB/s | 12-15GB/s | Premium laptops (2024+), Intel Core Ultra+ |
Gen 5 is the latest standard, but Gen 4 remains the most cost-effective option for most users.
Will My Laptop Support PCIe Gen 5?
Gen 5 support requires:
- Laptop released in 2024 or later (Intel Core Ultra, AMD Ryzen 8000+ series)
- Premium/professional model (Gen 5 is not standard on budget laptops yet)
- Official manufacturer support for Gen 5 in the BIOS
Check your laptop’s official specs. Search “[Model] PCIe Gen 5 support” or consult the manufacturer’s datasheet.
PCIe Gen 5 Laptops (2024-2026)
| Brand | Models | Status |
| Dell | XPS 13 (2024+), Latitude 5000 (2024+) | Some models support Gen 5 |
| HP | Elite Book, Dragonfly Pro (2024+) | Rumored Gen 5 support |
| Lenovo | ThinkPad X1 Carbon Gen 13+ | Gen 5 support expected |
| ASUS | ExpertBook, VivoBook Pro (2024+) | Select models only |
Gen 5 adoption is gradual. Verify your specific model’s official specifications before assuming Gen 5 support.
Performance: Gen 5 vs Gen 4 in Real Use
Theoretical speeds are impressive, but real-world differences vary by task:
| Task | Gen 5 Advantage | Noticeable? |
| Boot time | 5-10% faster | Barely noticeable (< 2 seconds) |
| File transfers (large files) | 15-30% faster | Yes, if transferring 50GB+ frequently |
| OS/application loading | 5-15% | Noticeable only for intensive workloads |
| Video editing (1080p) | 10-15% | Slight improvement in timeline scrubbing |
| Video editing (4K+) | 25-40% | Significant improvement in performance |
| Gaming | 0-5% | GPU-limited, no practical difference |
| Software compilation | 20-30% faster | Yes, for large projects |
Gen 5 matters most for professional workflows (4K video, large file transfers). For general use, Gen 4 is sufficient.
Cost Analysis: Gen 5 vs Gen 4
| Capacity | Gen 4 Price (2026) | Gen 5 Price (2026) | Premium |
| 512GB | £45-65 | £70-100 | +50-55% |
| 1TB | £70-90 | £120-160 | +40-50% |
| 2TB | £130-180 | £220-300 | +50-60% |
Gen 5 pricing remains 40-60% higher than Gen 4 through 2026. Prices should drop as adoption increases.
Should You Upgrade to Gen 5?
Upgrade to Gen 5 if:
- Your laptop supports Gen 5 and you work with 4K video professionally
- You do large file transfers (50GB+) frequently
- You compile code or work with massive datasets
- You have the budget (Gen 5 costs 50%+ more)
Stick with Gen 4 if:
- Your laptop is 2019-2023 and supports only Gen 3-4
- You use your laptop for general productivity (web, office, video streaming)
- You want maximum value (Gen 4 is mature and affordable)
- You game (GPU performance is the limiting factor)
Backward Compatibility
PCIe Gen 5 SSDs are backward compatible with Gen 4 slots but will operate at Gen 4 speeds. Example:
- Gen 5 SSD in Gen 4 slot = ~7.5GB/s (Gen 4 speeds)
- Gen 5 SSD in Gen 5 slot = ~14GB/s (Gen 5 speeds)
This is safe but wastes the Gen 5 drive’s potential. Only install Gen 5 drives in Gen 5-capable slots to maximize performance.
Gen 5 SSD Recommendations (2026)
| Brand | Model | Speed | Price Tier |
| Samsung | 990 Pro | 12.8GB/s (Gen 5) | Premium (£160-300) |
| Crucial | T700 | 12GB/s (Gen 5) | Upper-mid (£140-250) |
| Kingston | Fury Beast Pro | 7.1GB/s (Gen 4) | Mid-range (£80-150) |
| Western Digital | Black SN850X | 7.1GB/s (Gen 4) | Mid-range (£80-150) |
For Gen 5, Samsung and Crucial lead. For Gen 4, competition drives prices down significantly.
