Crucial T700 Review: 9.4/10 - Blazing PCIe Gen 5 speeds up to 12,400 MB/s
Overview
The Crucial T700 represents a massive leap in consumer SSD performance, harnessing the PCIe Gen 5 interface to deliver sequential speeds up to 12,400 MB/s read and 11,800 MB/s write. Powered by Micron’s own 232-layer 3D TLC NAND flash and the Phison E26 controller, the T700 nearly doubles the throughput of the fastest PCIe 4.0 drives. It is designed for enthusiasts, content creators, and professionals who demand uncompromising speed.
Design & Build
The T700 is an M.2 2280 drive available with or without an integrated heatsink. The heatsink version features an aluminum finned design with a nickel-plated copper core and thermal pads that effectively manage the significant heat output of PCIe 5.0 operation. Without adequate cooling, the drive can throttle under sustained loads, so Crucial recommends motherboard heatsinks or the included thermal solution. The double-sided PCB houses the Phison E26 controller and Micron NAND packages across two sides on 2TB and 4TB models.
Performance
In sequential benchmarks, the T700 achieves its rated 12,400 MB/s reads and 11,800 MB/s writes, redefining what consumer storage can do. Random 4K performance hits 1.5 million IOPS for both reads and writes. Real-world benefits are most apparent in large file transfers, where a 100GB video project moves in under 10 seconds. The drive supports Microsoft DirectStorage, and in compatible games asset loading is nearly instantaneous. The SLC cache on the 2TB model is approximately 300GB, after which sustained write speeds drop to roughly 2,000 MB/s.
Features
Crucial’s Storage Executive software provides firmware updates, drive health monitoring, and performance tuning. The T700 supports NVMe 2.0, TRIM, S.M.A.R.T. monitoring, and AES 256-bit encryption. Onboard power-loss protection helps safeguard data during unexpected shutdowns. The drive is fully compatible with PCIe 4.0 slots at reduced speeds, making it a future-proof investment for current builds.
Pros
- Blistering PCIe 5.0 sequential speeds
- Excellent 4K random IOPS performance
- Available with high-quality integrated heatsink
- Supports Microsoft DirectStorage
- 5-year warranty and strong endurance ratings
Cons
- Requires PCIe 5.0 slot for full performance
- Runs hot and needs active or robust passive cooling
- Premium price premium over PCIe 4.0 SSDs
- Real-world gains over Gen 4 are limited outside of large file workloads
Verdict
The Crucial T700 is a groundbreaking SSD that pushes consumer storage into a new performance tier. For those with PCIe 5.0-capable systems who work with massive files or want the absolute fastest load times, it is the current king of the hill.

How We Rate Products
Every product on ComfyTechCheck is scored on a 1 to 10 scale based on a structured evaluation framework. We assess products across five core criteria:
- Performance (30% weight): Speed, responsiveness, and real-world capability in its category.
- Build & Design (20% weight): Material quality, ergonomics, and aesthetic appeal.
- Features (20% weight): Breadth and usefulness of included functionality.
- Value (20% weight): Price-to-performance ratio relative to direct competitors.
- Battery Life or Reliability (10% weight): Endurance testing for portable devices, or long-term dependability for stationary gear.
Scores are assigned by our editorial team after hands-on testing or extensive research using verified user reports, expert analysis, and technical specifications. The weighted average produces the final rating you see on each review. This methodology is inspired by established consumer review standards from organizations such as Consumer Reports and Which?, adapted for the tech product categories we cover.
