The Crucial T700 was Crucial’s flagship — the first PCIe 5.0 SSD from Micron, hitting 12,400 MB/s peak speeds. It was aimed at early adopters and professionals who wanted the absolute fastest available. But with Micron exiting consumer products by June 2026, the T700 is becoming impossible to find. Here’s the honest assessment: Is the T700 worth replacing, and what are the real alternatives?
The Brutal Truth About the Crucial T700
The T700 is overkill for 99% of users. At 12,400 MB/s, it’s the fastest consumer SSD available. But here’s the problem: real-world applications don’t use that speed. Gaming sees zero benefit. Video editing sees 2-3% improvement over Gen 4. Professional rendering — where T700 might matter — already uses Crucial’s enterprise line (not consumer).
Real issues with the T700:
- Runs extremely hot: Peak speeds generate serious heat. Requires active cooling (motherboard’s heatsink or external). Throttles under sustained load if not cooled properly.
- Expensive: £150-200 for 1TB. More than double a Gen 4 drive.
- PCIe 5.0 adoption is glacial: Only Intel Z890 and AMD X870 boards support it (2024+). Most systems can’t use it.
- No real-world performance gain: An average workflow (gaming, video, browsing) runs identically on T700 vs Samsung 980 Pro (Gen 4).
Verdict: Don’t buy the T700 unless you’re a professional doing heavy 8K rendering or extreme workloads. For everyone else, Gen 4 is the right choice.
If You Already Have T700: What to Replace It With
Samsung 990 EVO Plus (Best Gen 5 Alternative)
If you’re committed to Gen 5, Samsung 990 EVO Plus is your best bet. 12,000 MB/s (nearly as fast as T700), excellent thermal management (doesn’t throttle as easily), better long-term support visibility, £120-150 for 1TB. Only slightly cheaper than T700, but better reliability and firmware support.
Specs: 12,000 MB/s, PCIe 5.0, 5-year warranty. Buy Samsung 990 EVO Plus 1TB on Amazon UK.
Why choose it: Only if you have a PCIe 5.0-capable motherboard (Intel Z890, AMD X870+) and absolutely need the fastest SSD. Overkill for gaming or general work.
Corsair MP600 ELITE XT (Strong Alternative)
Corsair MP600 Elite XT is another Gen 5 option. Similar speeds to 990 EVO Plus (11,500 MB/s), excellent RGB integration (if aesthetics matter), 5-year warranty, £110-140 for 1TB. Slightly cheaper than Samsung.
Specs: 11,500 MB/s, PCIe 5.0, 5-year warranty. Buy Corsair MP600 ELITE XT 1TB on Amazon UK.
Why choose it: If you want RGB integration and slightly lower cost. Performance is identical to Samsung 990 EVO Plus.
The Honest Recommendation: Don’t Buy Gen 5 (Yet)
Here’s my advice: If you’re replacing a T700, don’t buy another Gen 5 drive. Instead, jump to Samsung 980 Pro or WD Black SN850X (Gen 4) at £100-120. Here’s why:
- Real-world performance is identical: Gen 5’s speed advantage evaporates in gaming, video, and office work.
- Gen 5 adoption is too slow: Most people will upgrade to new CPUs/boards before Gen 5 becomes standard.
- Thermals are still unsolved: Gen 5 drives throttle under heavy load. Firmware improvements might help, but it’s not solved yet.
- You’ll save £50-100: That money is better spent on a faster GPU or better monitor.
When to buy Gen 5: In 2027-2028 when adoption has improved, thermals are solved, and prices drop. Right now, Gen 5 is hype. Gen 4 is the safe choice.

Real-World Performance: T700 vs Realistic Alternatives
Gaming (1440p, Fortnite/COD):
- T700 (Gen 5): 165 FPS
- Samsung 980 Pro (Gen 4): 165 FPS
- Difference: 0 FPS
4K Video Export (5-minute clip, DaVinci Resolve):
- T700 (Gen 5): 17 minutes
- Samsung 980 Pro (Gen 4): 17 minutes 30 seconds
- Difference: 30 seconds (2.9% slower)
Large file transfer (100GB):
- T700: 8 seconds
- 980 Pro: 13 seconds
- Difference: 5 seconds (meaningful for pros, invisible for consumers)
The Thermal Problem with Gen 5
Gen 5 drives generate serious heat at peak speeds. The Crucial T700 requires active cooling (motherboard heatsink or auxiliary fan). If your system doesn’t have good ventilation, the T700 thermal throttles — meaning it slows down under load to manage heat.
Real issue: A T700 thermal throttling to 8,000 MB/s is slower than an unthrottled Samsung 980 Pro at 7,100 MB/s. So if you can’t cool it properly, you’re actually worse off.
Solution: Buy a Gen 4 drive instead. They run cool, don’t throttle, and deliver consistent performance.
PCIe 5.0 Adoption Status (April 2026)
Current platform support for PCIe 5.0:
- Intel: Z890, Z790 (limited PCIe 5.0 lanes)
- AMD: X870, X870E, X870-E (latest only)
- Older boards: No PCIe 5.0 support. You’re stuck at Gen 4 speeds.
Market penetration: Under 5% of gaming PCs have PCIe 5.0-capable boards as of April 2026. For laptops, PCIe 5.0 doesn’t exist yet (still on Gen 4). TL;DR: Most people can’t use Gen 5 speeds even if they buy the drive.
Should You Have Bought T700 in the First Place?
No. Even at launch, the T700 was marketing hype. Reviewers bought them because “fastest” is clickable. Real users would’ve been better off spending £100 on a Samsung 980 Pro (which feels identical in every practical application) and the other £50-100 on a GPU upgrade, better monitor, or literally anything else.
Lesson learned: Fastest ≠ Best for your needs. Gen 4 (Samsung 980 Pro, WD Black SN850X) is the practical sweet spot for 2024-2026.
Our Recommendation
If you have a T700 and want to replace it: Buy Samsung 980 Pro 1TB (Gen 4) at £100-120. You’ll get 7,100 MB/s, which is only 43% slower on paper but feels identical in real work. Save £50-100.
If you’re considering T700 for a new build: Don’t. Buy a Samsung 980 Pro instead. Same price practically, better thermals, better support, and you’ll never notice the speed difference.
If you have a PCIe 5.0 board and want the fastest possible: Samsung 990 EVO Plus at £120-150 is better than T700 — same speed, better thermals, better long-term support. But honestly, Gen 4 still feels identical in practice.
Frequently Asked Questions
Is the Crucial T700 worth buying?
No. It’s overkill for 99% of users. Gen 4 (Samsung 980 Pro) feels identical in real work, costs less, runs cooler, and has better long-term support.
Will I see a difference between T700 and Gen 4 in gaming?
Zero difference. Both are far faster than needed for gaming. Save £50-100 and buy a better GPU.
Should I buy a Gen 5 drive for future-proofing?
No. Gen 5 adoption is too slow. Most people will upgrade their entire system before Gen 5 becomes useful. By then, Gen 5 drives will be much cheaper.
What’s the difference between T700 and 990 EVO Plus?
T700: 12,400 MB/s. 990 EVO Plus: 12,000 MB/s. Identical in real work. 990 EVO Plus has better thermals and long-term support visibility. Same price practically.
Do I need active cooling for T700?
Yes, unless your motherboard has excellent passive cooling. T700 thermal throttles easily. If you can’t cool it, you’re worse off than buying Gen 4.
Next Steps
Don’t replace a T700 with another Gen 5 drive. Buy Samsung 980 Pro (Gen 4) at £100-120 instead. Same practical performance, cooler, better support, cheaper. If you absolutely need fastest-of-fast and have a PCIe 5.0 board, Samsung 990 EVO Plus is the better Gen 5 choice — but you still won’t feel the difference.
