Crucial SSDs After Micron Exit
Micron announced Q4 2025 that consumer SSD operations cease in Q2 2026, affecting all Crucial products (NVMe and SATA). Timeline and implications:
- By June 2026: No new Crucial SSDs manufactured. Existing inventory will be sold through distributors at inflated prices.
- Warranty support: Likely transfers to channel partners or discontinued entirely. New warranty claims post-2026 may be rejected.
- Firmware updates: Stopped as of Q4 2025. No compatibility patches for new Windows/macOS versions.
- Compatibility verification: New laptop model testing halted. If you upgrade to a new system post-2026, Crucial warranty may not cover compatibility.
- Pricing: Expect 20–35% price increases on remaining Crucial stock as buyers rush to capture the last units. After June 2026, prices will normalise as users migrate to Samsung/WD.
Existing Crucial SSDs remain fully functional indefinitely and require no action. If you own a Crucial drive, it will not fail when Micron exits. New purchases only make sense if stock is available at pre-exit pricing and you upgrade within 2–3 years.
Frequently Asked Questions
Is Samsung or WD better for laptop SSD upgrades?
Neither is objectively superior—it depends on workload. Samsung offers proven reliability, sustained performance under load, and longest support lifecycle (5+ years guaranteed). WD Black delivers near-identical real-world performance at 15–25% lower cost and excels in gaming. For gaming, choose WD. For content creation or 5+ year ownership, choose Samsung.
NVMe vs SATA—which should I buy?
Always choose NVMe if your laptop has an M.2 slot (all systems from 2017+). NVMe is 10–15x faster than SATA, enables better thermal management, and ensures compatibility with future laptops. SATA is only necessary if your laptop lacks NVMe capability (older pre-2016 systems).
Is Crucial P5 Plus a good SSD?
Yes, but with caveats. The P5 Plus delivers solid 6600 MB/s performance and 600 TBW endurance, suitable for gaming and productivity. However, Crucial’s discontinuation means post-2026 warranty claims are uncertain. Comparable WD and Samsung drives offer better long-term support at similar prices.
Can I use a desktop SSD in my laptop?
Yes, if your laptop has an M.2 slot. Desktop and laptop NVMe drives use identical M.2 connectors. However, desktop drives often have higher power consumption and heat output, potentially causing thermal throttling or battery drain on thin laptops. Laptop-optimised drives (like Samsung 990 EVO) include thermal controls for lower power use. Check your laptop’s thermal specifications before installing desktop-grade drives.
What’s the best budget SSD for laptops?
WD SN580 is the best value—5100 MB/s with DRAM cache at £50–60. Crucial P3 (£38–52) is cheaper but lacks cache and endurance (110 TBW). Samsung 980 (£55–70) offers brand reliability but costs 15% more. For budget buyers prioritising performance-per-pound, WD SN580 wins decisively.
How much faster is NVMe than SATA in real use?
In synthetic benchmarks, NVMe is 5–15x faster (5000 MB/s vs 550 MB/s sequential). In real-world use, the difference is more subtle: Windows boot times: 15–20 seconds (NVMe) vs 25–35 seconds (SATA). Application launches: 1–2 seconds faster on NVMe. For everyday productivity, the difference is noticeable but not dramatic. For gaming and video editing, NVMe’s sustained speed advantage is significant.
What does TBW endurance mean for laptop SSDs?
TBW (Terabytes Written) is the total data your drive can write before failure. A 500 TBW drive can write 500TB before warranty expiration. For typical users writing 50GB/month, a 500 TBW drive lasts 10,000 months (833 years). Only video editors and data scientists exceed TBW limits within a typical system lifespan (5 years). Higher TBW (900+ for WD, 1200+ for Samsung) provides headroom for intensive workloads.
Should I buy Crucial now before discontinuation?
Only if: (1) price is 20%+ lower than Samsung/WD equivalents, (2) you plan to upgrade within 3 years, (3) stock is readily available. If any condition fails, buy Samsung or WD instead. The 15–25% cost saving doesn’t justify warranty uncertainty post-2026.
