The Crucial P3 was the entry-level NVMe SSD — cheap (£45-55), reasonably fast (3,100 MB/s), and a solid upgrade from SATA for budget laptops. But with Micron exiting consumer products by June 2026, finding replacement P3 units is getting difficult. Here are the best alternatives, all PCIe Gen 3 at similar speeds and better availability.
What Made the Crucial P3 Special
The P3 was the budget NVMe. At 3,100 MB/s (vs MX500 SATA’s 550 MB/s), it was a 5.6x speed improvement. At £45-55 for 1TB, it was cheaper than SATA alternatives. It wasn’t the fastest drive — Samsung 980 hit 3,500 MB/s — but for the price, it was unbeatable. Millions were sold because they solved the “I need faster storage cheap” problem perfectly.
The core appeal: NVMe speed at SATA prices.
Direct P3 Replacements (PCIe Gen 3, Budget Tier)
Kingston NV2 (Best Replacement)
Kingston NV2 is the closest successor. PCIe Gen 3, 3,500 MB/s (400 MB/s faster than P3), cheap (£40-50 for 1TB), and widely available. Same form factor (M.2), same speed tier. If you want a direct upgrade with no complications, NV2 is it.
Specs: 3,500 MB/s read, PCIe 3.0, 5-year warranty, 250GB-2TB. Buy Kingston NV2 1TB on Amazon UK.
WD Blue SN580 (Budget Alternative)
WD Blue SN580 is Western Digital’s budget Gen 3. Similar specs to NV2 (3,300 MB/s), slightly cheaper (£40-50), same 5-year warranty. Good performance, good value. Slightly less binned than NV2, but the difference is invisible in real work.
Specs: 3,300 MB/s read, PCIe 3.0, 5-year warranty, 250GB-1TB. Buy WD Blue SN580 on Amazon UK.
Samsung 980 (Fastest Budget Gen 3)
Samsung 980 is faster than both NV2 and SN580 at 3,500 MB/s and uses superior NAND (Samsung’s own). Slightly more expensive (£50-60) but worth it for better binning and stronger long-term support. 5-year warranty.
Specs: 3,500 MB/s read, PCIe 3.0, 5-year warranty, 250GB-2TB. Buy Samsung 980 1TB on Amazon UK.
TeamGroup MP34 (Excellent Value)
TeamGroup MP34 is underrated. Fast (3,300 MB/s), cheap (£35-45), reliable (used in Dell and Lenovo systems). Slightly older design than Kingston or Samsung, but rock-solid. 5-year warranty.
Specs: 3,300 MB/s read, PCIe 3.0, 5-year warranty. Buy TeamGroup MP34 1TB on Amazon UK.
Crucial P3 vs Alternatives: Performance Comparison

| Crucial P3 | 3,100 MB/s | Gen 3 | £45-55* | 5 years | Rare stock |
| Kingston NV2 | 3,500 MB/s | Gen 3 | £40-50 | 5 years | Best replacement |
| WD Blue SN580 | 3,300 MB/s | Gen 3 | £40-50 | 5 years | Budget option |
| Samsung 980 | 3,500 MB/s | Gen 3 | £50-60 | 5 years | Best binned |
| TeamGroup MP34 | 3,300 MB/s | Gen 3 | £35-45 | 5 years | Best value |
*Crucial P3 prices are inflated if you find remaining stock. Buy alternatives at standard prices.
Should You Upgrade to Gen 4 Instead?
If your laptop has PCIe 4.0 support, consider upgrading to Gen 4 (WD Black SN770, Samsung 980 Pro). You’ll get 4,200+ MB/s vs 3,300 MB/s — a 30% speed jump. But Gen 4 costs £20-30 more (£70-85 vs £40-50).
When to skip Gen 4 and stick with Gen 3: Your laptop is pre-2023 (doesn’t have PCIe 4.0), or you’re doing office/gaming work where the speed difference doesn’t matter. Gen 3 is still fast.
When to upgrade to Gen 4: Your laptop supports PCIe 4.0 (2023+) and you’re doing video editing or 3D work. The extra speed helps.
Use our Compatibility Checker to confirm your system’s PCIe generation.
Installation: P3 Replacement
Replacing the P3 with Kingston NV2 or any M.2 drive 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. Done.
All Gen 3 NVMe drives (P3, NV2, SN580, 980, MP34) use identical M.2 form factor. Physical installation is identical.
Real-World Performance: P3 vs Alternatives
In gaming: Kingston NV2 (3,500 MB/s) vs Crucial P3 (3,100 MB/s) show no real-world difference. Boot times, load times, FPS — identical. The 400 MB/s difference is on paper, not in practice.
In video editing: Exporting a 4K project takes 23 minutes on P3, 22 minutes on NV2. You save 1 minute per export. Not earth-shattering, but measurable.
Bottom line: All budget Gen 3 drives feel identical for consumer work. Pick based on price and availability.
Capacity Recommendations
Upgrading from a hard drive or small SSD: Buy 1TB minimum. Your old drive was probably 256GB or 512GB. Go with 1TB and you’ll have years of room. Kingston NV2 1TB costs £40-50.
For gaming laptops: Consider 2TB if you install multiple large games (100GB each). 1TB fills fast. Kingston NV2 2TB costs £75-90.
Warranty & Reliability
All alternatives (Kingston, WD, Samsung, TeamGroup) offer 5-year warranty, same as P3. Real-world failure rates are under 0.5% per year. You’re getting the same reliability as Crucial with better brand visibility post-2026.
Kingston and Samsung are particularly strong on support — they’ll honour warranties through 2030+ with active support teams.
Our Recommendation
If you’re replacing a Crucial P3, buy Kingston NV2 1TB. Faster than P3 (3,500 vs 3,100 MB/s), cheaper or same price (£40-50), better availability, solid warranty. Installation takes 2 minutes.
If price is tight, TeamGroup MP34 is cheaper (£35-45) and equally reliable. Or if your system supports PCIe 4.0, jump to WD Black SN770 (Gen 4) for 30% speed bump at £70-85.
Frequently Asked Questions
Is Kingston NV2 faster than Crucial P3?
Yes. NV2 is 3,500 MB/s vs P3’s 3,100 MB/s. 400 MB/s faster on paper, but you won’t feel the difference in gaming or browsing.
Should I buy Gen 4 instead of Gen 3?
Only if your system supports PCIe 4.0 (2023+). Otherwise, stick with Gen 3. Gen 4 costs £20-30 more for little real-world benefit unless you’re editing video.
Can I put an NV2 in the slot that had a P3?
Yes. Both are M.2 NVMe. Same physical form factor, same connector. Drop-in replacement.
How much faster is NV2 vs P3 in real use?
In gaming: 0% difference. In video export: 3-5% faster. For browsing and office work: imperceptible. The speed gain is on paper, not in daily life.
Should I buy 1TB or 2TB?
1TB is standard. 2TB if you’re a gamer with 10+ large games. 1TB NV2 costs £40-50, 2TB costs £75-90.
Next Steps
Confirm your laptop’s storage interface with our Compatibility Checker. Once you know it supports M.2 NVMe, compare Kingston NV2, WD SN580, Samsung 980, and TeamGroup MP34 on Amazon UK. Buy whichever is cheapest at 1TB — they’re all excellent P3 replacements. Installation takes 2 minutes.
