M.2 PCIe Gen4x4 NVMe 2TB SSD - High-Speed PS5 & PC Upgrade

In this review the Yottamaster T7400 2TB SSD is evaluated as a high-performance internal drive aimed at gamers and creative professionals who need fast transfers and sustained reliability. The single biggest reason to buy is its combination of PCIe Gen4x4 bandwidth and NVMe 2.0 support delivering up to 7450MB/s read and 6500MB/s write under optimal conditions, which materially reduces load and transfer times for large files and modern games. The drive also emphasizes longevity and thermal management, which matters for extended gaming sessions and heavy render workloads.

Key Features

• PCIe Gen4x4 NVMe 2.0: Provides very high sequential read and write throughput for faster game loads and quicker file transfers on supported systems.
• High Performance Speeds: Rated up to 7450MB/s read and 6500MB/s write to accelerate workflows like 4K video editing and large asset loading.
• 232-layer 3D TLC NAND: Uses modern NAND construction for durability and consistent performance across sustained workloads.
• Advanced Cooling: Includes a copper cooling vest, silicone thermal pad, and graphene spreader to keep temperatures down during long sessions.
• Endurance and Reliability: Built for heavy use with a TBW of 1000 and MTBF beyond 1,500,000 hours to handle frequent writes and rewrites.
• Modern Drive Features: Supports SLC caching, Host Memory Buffer, TRIM and secure erase to maintain responsiveness and data integrity.

Who It's For

The T7400 is best for PC and console gamers who want snappy load times, and for video editors or professionals who move very large files and need Gen4 speed. It is a good option for tech enthusiasts upgrading laptops and desktops that support M.2 PCIe Gen4x4 drives and need roomy 2TB capacity.

Those with older systems limited to PCIe Gen3 will not see the full advertised speeds and may want to consider a Gen3-optimized drive instead. Also, users who only need small capacity storage or budget options could choose lower-capacity NVMe drives for better price per gigabyte.

Pros & Cons

Pros

• Top-tier sequential read/write speeds that reduce game and project wait times.
• Robust thermal solution to sustain performance during extended heavy use.
• High endurance specifications and modern NAND for long-term reliability.
• Supports features like SLC caching and TRIM to keep performance steady over time.

Cons

• Actual peak speeds require a PCIe Gen4 platform and ideal conditions to approach the rated numbers.
• Higher-end cooling hardware may add slight installation thickness compared with bare M.2 sticks.

Specifications

Our Verdict

The Yottamaster T7400 2TB is a strong value for users with PCIe Gen4 systems who need high sequential throughput and solid endurance. Its comprehensive cooling and modern features make it a sensible upgrade for gamers and creatives who want to reduce wait times and rely on sustained performance without frequent thermal throttling.

Frequently Asked Questions
