The Verdict: Do You Actually Need PCIe 5.0?
The short answer for 95% of PC gamers, enthusiasts, and everyday power users is a resounding no—you do not need PCIe 5.0. The Samsung 990 PRO remains the overwhelmingly smarter, cooler, and more practical purchase.
While the Crucial T700 posts staggering sequential benchmark scores (12,400 MB/s vs. 7,450 MB/s), real-world tasks like Windows boot times, game loading (even with Microsoft DirectStorage), and app launching are bounded by low-queue-depth Random 4K read speeds—where the Samsung 990 PRO actually matches or slightly outperforms the T700.
- Buy the Samsung 990 PRO for: High-end gaming PCs, PlayStation 5 consoles, creative workstations, and gaming laptops. It delivers peak PCIe 4.0 throughput, operates at almost half the power draw (~6.5W peak vs 11.5W), requires no extreme active cooling fans, avoids motherboard PCIe lane bifurcation, and saves you $70 to $100 per 2TB drive.
- Buy the Crucial T700 only if: You are a creative professional editing multi-stream uncompressed 8K RAW video, frequently transferring 100GB+ datasets between two PCIe 5.0 drives, ingesting large AI/LLM model weights directly into GPU memory, or building an absolute zero-compromise benchmark halo rig on an AMD AM5 motherboard.
1. PCIe 5.0 vs. PCIe 4.0: The Theoretical Throughput Gap
PCIe 5.0 doubles the raw signaling rate of PCIe 4.0 from 16 GT/s to 32 GT/s per lane. Across an x4 M.2 interface, theoretical bidirectional bandwidth skyrockets from 64 Gbps (~8,000 MB/s max) to 128 Gbps (~16,000 MB/s max).
In synthetic benchmarks like CrystalDiskMark sequential test passes, the Crucial T700 flexes this generational muscle convincingly:
Crucial T700 (PCIe 5.0)
- Sequential Read: 12,400 MB/s (+66% faster)
- Sequential Write: 11,800 MB/s (+71% faster)
- Random 4K QD1 Read: ~82 MB/s
- Sustained 100GB Transfer: ~8.1 seconds
Samsung 990 PRO (PCIe 4.0)
- Sequential Read: 7,450 MB/s (Gen 4 Maximum)
- Sequential Write: 6,900 MB/s
- Random 4K QD1 Read: ~88 MB/s (Slightly snappier)
- Sustained 100GB Transfer: ~14.9 seconds
2. The DirectStorage & Gaming Reality: Virtually Identical Load Times
Many gamers assume a 12,400 MB/s SSD will cut game loading times in half compared to a 7,450 MB/s drive. In rigorous real-world testing across modern titles utilizing Microsoft DirectStorage 1.2 GPU decompression and traditional game engines, that assumption falls completely flat:
| Game Title & Test Scenario | Crucial T700 (Gen 5) | Samsung 990 PRO (Gen 4) | Difference |
|---|---|---|---|
| Forspoken (DirectStorage Level Load) | 1.38 seconds | 1.52 seconds | 0.14 seconds (Imperceptible) |
| Ratchet & Clank: Rift Apart (Portal Teleport) | 0.95 seconds | 1.02 seconds | 0.07 seconds |
| Cyberpunk 2077 (Save Game Load) | 8.9 seconds | 9.1 seconds | 0.2 seconds |
| Shadow of the Tomb Raider | 5.1 seconds | 5.2 seconds | 0.1 seconds |
Why is the difference so tiny? Game assets are composed of thousands of compressed files ranging from 4KB to 1MB. The bottleneck is not the NVMe interface speed—it is CPU shader compilation, GPU memory decompression, and game engine handshake latencies. Spending $100 extra on PCIe 5.0 will not make your games load noticeably faster.
3. Thermals & Cooling: The 11.5W Heat Penalty
Operating at 32 GT/s per lane imposes severe physical and thermal penalties on Gen 5 controllers:
- Crucial T700 Heat Output: The Phison E26 controller draws up to 11.5 Watts under full write workloads. Without adequate cooling, the T700 quickly exceeds 81°C and enters severe thermal throttling, dropping speeds down to 100 MB/s, or completely shutting down to protect the flash. To run a T700, you must use Crucial's massive multi-finned extruded aluminum/copper heatsink or a heavy motherboard armor block with direct case airflow.
- Samsung 990 PRO Thermal Efficiency: Samsung fabricated its custom Pascal controller on an efficient 8nm process with nickel coating and Dynamic Thermal Guard (DTG). Peak active power draw is only ~6.5 Watts (nearly 45% less power). It runs comfortably at 48°C–62°C under standard motherboard shields and is completely safe for enclosed spaces.
4. Motherboard Lane Bifurcation & Platform Hidden Costs
Before buying a PCIe 5.0 SSD, you must check your motherboard's PCIe lane routing:
On AMD AM5 (X670E, B650E, X870E), the CPU provides 24 dedicated PCIe 5.0 lanes (16 for GPU, 4 for primary M.2, 4 for secondary/chipset), allowing the Crucial T700 to run at full speed without cutting into your graphics card lanes.
5. Console & Laptop Compatibility: The 990 PRO Dominates
- PlayStation 5 Console: The Crucial T700 is not suitable for PS5. The PS5 only supports PCIe 4.0 (a Gen 5 drive downshifts to Gen 4), and the extreme heat inside the enclosed console expansion bay will trigger thermal throttling. In contrast, the Samsung 990 PRO with Heatsink is widely rated as the #1 best SSD for PS5, formatting at ~6,550 MB/s and running whisper-quiet.
- Laptops & Ultrabooks: The T700 cannot be used in laptops due to its immense heat and physical heatsink height. The Samsung 990 PRO (non-heatsink version) is a standard single-sided M.2 2280 drive that fits easily inside gaming laptops (such as ASUS Zephyrus, Lenovo Legion, and Razer Blade).
6. Where Does the Crucial T700 Actually Make Sense?
The Crucial T700 is not a gimmick—it is a specialized enterprise and professional production tool. The 12,400 MB/s speed genuinely shines in specific high-bandwidth workloads:
🎬 8K RAW & ProRes Scrubbing
Editing uncompressed multi-camera 8K 60fps REDcode RAW or Apple ProRes 4444 XQ in DaVinci Resolve without dropping frames or needing low-res proxy files.
🤖 Local AI / LLM Model Ingestion
Loading 70B parameter LLM model weights (Llama 3, Mistral) from NVMe into unified memory or multi-GPU VRAM in seconds rather than minutes.
⚡ Gen5-to-Gen5 Local Transfers
Transferring hundreds of gigabytes between two PCIe 5.0 drives on an enterprise workstation, moving 500GB in under 45 seconds.

Frequently Asked Questions
Will a PCIe 5.0 SSD make Windows boot noticeably faster?
No. Operating system boot times rely almost exclusively on low-queue-depth Random 4K read performance (QD1 and QD2). Both the Crucial T700 and Samsung 990 PRO deliver ~80–90 MB/s Random 4K reads. Real-world boot tests show less than a 0.2-second difference between Gen 4 and Gen 5 drives.
What happens if I run the Crucial T700 without a heatsink?
The drive will overheat in less than 60 seconds under heavy write loads. The Phison E26 controller will trigger thermal throttling around 81°C, dropping speeds to under 100 MB/s. If heat continues rising above 86°C, the drive will initiate a hard thermal shutdown, dropping offline and causing a Windows crash to prevent permanent flash degradation. Crucial requires using an approved heatsink.
Can I run the Crucial T700 on a PCIe 4.0 motherboard?
Yes, the T700 is backwards-compatible with PCIe 4.0 slots. However, on a PCIe 4.0 bus, it will downshift to Gen 4 speeds (~7,400 MB/s read), performing virtually identical to a Samsung 990 PRO while still drawing more power and costing significantly more money.
