Yottamaster T7400 1TB M.2 PCIe Gen4x4 NVMe SSD - High-Speed Storage

In this review the Yottamaster T7400 1TB M.2 PCIe Gen4x4 NVMe SSD is evaluated for gamers, creative professionals, and power users who need fast, reliable internal storage. The bottom line is simple: this drive delivers class-leading sequential speeds and a strong thermal solution, making it a straightforward upgrade for anyone moving from SATA or PCIe Gen3. The combination of NVMe 2.0 performance and a multi-layer cooling system is the single biggest reason to consider this drive if large file transfers, game load times, or heavy multitasking are priorities.

Key Features

• PCIe Gen4x4 NVMe: Up to 7450MB/s read and 6500MB/s write under optimal conditions for dramatically faster file transfers and shorter load times.
• High IOPS for multitasking: Around 1000K IOPS ensures responsive system performance when running games, editing video, or working with large databases.
• 232-layer 3D TLC NAND: Built for durability and steady throughput during sustained workloads, useful for content creators and professionals.
• Advanced cooling: Copper cooling vest, silicone thermal pad and graphene heat spreader combined with intelligent thermal control reduce throttling during long sessions.
• Data management features: SLC caching, Host Memory Buffer (HMB), error correction, TRIM and secure erase help maintain consistent performance and data integrity.
• Solid endurance: A 500 TBW rating and MTBF over 1,500,000 hours make it suitable for intensive daily use.

Who It's For

The T7400 is aimed at PC gamers upgrading storage for faster level loads and reduced asset streaming delays, and at video editors or 3D artists who need high sequential throughput for large media files. Its strong IOPS and modern NVMe 2.0 interface also benefit power users running virtual machines, databases, or professional applications.

Users who primarily need archival cold storage or very low-cost bulk capacity may prefer slower SATA drives or larger-capacity alternatives. Also, older systems without PCIe Gen4 support will not reach the peak speeds this drive can deliver, though they will still see a boost over Gen3 drives.

Pros & Cons

Pros

• Exceptional sequential read and write performance for demanding tasks and fast game loading.
• Robust cooling approach reduces thermal throttling in sustained workloads.
• Reliable flash and endurance figures with SLC caching and error correction for stable performance over time.
• Supports modern NVMe features like TRIM, secure erase and RAID compatibility for flexible system use.

Cons

• Peak Gen4 speeds require a motherboard or console that supports PCIe Gen4; older systems will see lower performance.
• Higher-end cooling and features add complexity compared with ultra-basic NVMe drives for very casual users.

Frequently Asked Questions

Will this drive work in a PS5?
Yes, the T7400's M.2 PCIe Gen4x4 NVMe interface and high sequential speeds make it compatible as an expanded internal storage option for PS5 models that accept M.2 Gen4 drives.

Does it need a heatsink?
It includes a copper cooling vest, silicone thermal pad and graphene spreader, so additional heatsinks are generally unnecessary unless your system has atypical airflow constraints.

Is it suitable for sustained video editing?
Yes, the high write speeds, SLC caching and robust cooling make it well suited for editing large video files and other sustained workloads.
