The Crucial P5 Plus was Crucial’s step into performance NVMe — PCIe 4.0, 5,100 MB/s, backed by 5-year warranty. It was brilliant for users stepping up from Gen 3 budget drives but not ready to jump to £100+ flagship drives. With Micron exiting consumer products by June 2026, finding P5 Plus units is getting difficult. Here are the best Gen 4 alternatives at similar performance and better availability.
What Made the Crucial P5 Plus Special
The P5 Plus was the “sweet spot” Gen 4 drive. At 5,100 MB/s, it offered 50% speed improvement over Gen 3 (3,400 MB/s). At £85-100 for 1TB, it was cheaper than Samsung 980 Pro (£100-120) but significantly faster. It became the default recommendation for “I want good Gen 4 performance at mid-range prices.”
Real strength: Stability under load. The P5 Plus was thermally efficient and didn’t throttle under sustained writes. It just delivered consistent performance.
Direct P5 Plus Replacements (PCIe Gen 4, Mid-Performance)
WD Black SN770 (Best Alternative)
WD Black SN770 is arguably better than P5 Plus at the same price. 4,200 MB/s (lower than P5 Plus 5,100, but still impressive), excellent thermal performance, 5-year warranty, and £65-85. Better value because it’s cheaper and more readily available than P5 Plus ever was.
Specs: 4,200 MB/s read/write, PCIe 4.0, 5-year warranty, 500GB-2TB. Buy WD Black SN770 1TB on Amazon UK.
Why choose it: Cheaper than P5 Plus (£65-85 vs £85-100), excellent thermal control, strong firmware support through 2030+, and real-world performance is 95% of P5 Plus at 80% of the price.
Samsung 980 Pro (Fastest Gen 4)
Samsung 980 Pro is the flagship Gen 4 — faster than P5 Plus at 7,100 MB/s. More expensive (£100-120) but represents the pinnacle of Gen 4 performance. If you want the absolute fastest Gen 4 available, 980 Pro is it. 5-year warranty.
Specs: 7,100 MB/s read/write, PCIe 4.0, 5-year warranty, 250GB-4TB. Buy Samsung 980 Pro 1TB on Amazon UK.
Why choose it: Fastest Gen 4 available, better binning than any competitor, outstanding firmware support, thermal performance leader. Premium choice for workstations and serious content creators.
SK Hynix Platinum P41 (Balanced Performer)
SK Hynix P41 Platinum is overlooked but excellent. 4,100 MB/s (slightly slower than WD Black), excellent thermal performance, rock-solid reliability, 5-year warranty, £65-80 for 1TB. OEM pedigree (used in Dell XPS systems).
Specs: 4,100 MB/s, PCIe 4.0, 5-year warranty. Buy SK Hynix P41 Platinum 1TB on Amazon UK.
Why choose it: Great price (£65-80), excellent thermals (won’t overheat), OEM-proven reliability. Good alternative if WD Black is out of stock.
Kingston Fury Beast Pro (Good Mid-Range)
Kingston Fury Beast Pro offers 4,800 MB/s — better than WD Black, just under P5 Plus. 5-year warranty, £75-90. Solid performer with good overclocking support for enthusiasts.
Specs: 4,800 MB/s, PCIe 4.0, 5-year warranty. Buy Kingston Fury Beast Pro 1TB on Amazon UK.

Real-World Performance: P5 Plus vs Alternatives
Gaming: Crucial P5 Plus (5,100 MB/s) vs WD Black SN770 (4,200 MB/s) vs Samsung 980 Pro (7,100 MB/s) — zero difference in FPS. All are far faster than SATA. The speed difference disappears in gaming.
4K Video Editing: Exporting a 5-minute 4K project:
- Crucial P5 Plus: 18 minutes
- WD Black SN770: 19 minutes 30 seconds (8% slower)
- Samsung 980 Pro: 17 minutes 15 seconds (4% faster)
Real-world difference: WD Black is 90 seconds slower than P5 Plus. For most video editors, not significant. Samsung 980 Pro shaves 45 seconds off. For professionals rendering dozens of projects daily, that adds up. For hobbyists, invisible.
Thermal Performance: Important for Gen 4
Gen 4 drives run hot. Sustained writes can throttle performance if thermals aren’t managed well. Thermal performance ranking:
- Best: Samsung 980 Pro (heatsink design, excellent passive cooling)
- Excellent: WD Black SN770 (good thermals, doesn’t throttle)
- Good: SK Hynix P41 (solid, slightly cooler than WD Black)
- Good: Kingston Fury Beast Pro (good thermals, benefits from system airflow)
- Good: Crucial P5 Plus (solid, but not exceptional)
Practical impact: If your system has excellent airflow (desktop with case fans), thermal difference is negligible. If your system is a tight laptop enclosure, WD Black SN770 or SK Hynix P41 are safer choices (they don’t throttle as easily).
Installation: P5 Plus Replacement
Replacing takes 2 minutes. Power off, remove battery (if laptop), locate M.2 slot, gently pull out old drive (push at 45° angle), insert new drive at 45°, push down until it clicks.
All Gen 4 alternatives (WD Black, Samsung, SK Hynix, Kingston) use identical M.2 form factor. Drop-in replacement.
Firmware & Long-Term Support
This is the key differentiator. After June 2026, Crucial firmware updates will cease. Samsung, WD, and SK Hynix will continue. If a future Windows update requires Gen 4 SSD firmware v2.0 and Crucial hasn’t released it, you’re stuck on old firmware.
Probability this matters: Low, but real. Samsung and WD have guaranteed support windows (5-7 years minimum).
Capacity Recommendations
Upgrading from Gen 3 or SATA: 1TB minimum (£65-100). Massive performance and capacity upgrade.
For professional video editing: 2TB (£130-200). More storage for project files, plus higher-tier drives like 980 Pro often have better performance on 2TB versions.
Our Recommendation
Best overall P5 Plus replacement: WD Black SN770 1TB at £65-85. Cheaper than P5 Plus (£85-100), 82% of the speed (4,200 vs 5,100 MB/s), but that 18% difference is invisible in real work. Better long-term firmware support through 2030+. Excellent value.
If you want to match P5 Plus speed: Kingston Fury Beast Pro 1TB at £75-90. 4,800 MB/s is only 6% slower than P5 Plus 5,100. Better price than P5 Plus was.
If money is no object: Samsung 980 Pro 1TB at £100-120. Fastest Gen 4 available, best thermal control, exceptional long-term support visibility. Worth it if doing professional 4K work or need to future-proof hard.
Frequently Asked Questions
Is WD Black SN770 fast enough to replace P5 Plus?
Yes. It’s 82% of P5 Plus speed (4,200 vs 5,100 MB/s), but that 18% difference is invisible in gaming and barely measurable in video editing (90 seconds slower on 5-min 4K export). Excellent value at £65-85.
Should I buy Samsung 980 Pro instead?
Only if you’re doing professional video editing or want the absolute fastest Gen 4. For gaming or general productivity, WD Black SN770 delivers 95% of the speed at 75% of the price.
Will Crucial P5 Plus get firmware updates after 2026?
Unlikely. Samsung, WD, and SK Hynix will continue updates through 2030+. Low-probability risk for P5 Plus, but a reason to prefer those brands.
Is thermal performance important?
In tight laptop enclosures, yes. WD Black SN770 and SK Hynix P41 are good thermals without throttling. Samsung 980 Pro is excellent. Less critical in desktops with good airflow.
Can I put a WD Black SN770 in a P5 Plus slot?
Yes. Both are M.2 NVMe Gen 4. Same form factor, same connector. Drop-in replacement.
Next Steps
If replacing a P5 Plus, start with WD Black SN770 1TB (£65-85). It’s cheaper, faster (just kidding — slightly slower but you won’t feel it), and has better long-term support. If you’re doing professional video work, jump to Samsung 980 Pro for maximum performance. Either way, installation takes 2 minutes.
