Biwin Black Opal NV7400 2TB

Manufacturer: Biwin

The Biwin Black Opal NV7400 2TB is a high-throughput M.2 NVMe solid-state drive built around the Maxiotek MAP1602A Falcon Lite Gen4 controller. Targeting users who need fast internal storage, it offers sequential read speeds reaching 7450 MB/s and sequential writes up to 6500 MB/s, making it a notable option among PCIe 4.0 drives in the 2TB capacity range.

On the technical side, the NV7400 uses TLC NAND storage with HMB (Host Memory Buffer) in place of dedicated DRAM cache, operating through a 4-channel controller configuration over a PCIe 4.0 interface with NVMe 2.0 support. Random performance is rated at 1,000,000 IOPS for reads and 900,000 IOPS for writes. The drive carries a 2000 TBW endurance rating, an MTBF of 1.5 million hours, a maximum operating temperature of 70°C, and comes backed by a 5-year warranty. It ships without an integrated heatsink and does not include hardware-level AES encryption support.

Pros
  • Sequential read speed of 7450 MB/s and write speed of 6500 MB/s indicate strong throughput for large file transfers
  • Random read performance rated at 1,000,000 IOPS supports demanding workloads involving many simultaneous small operations
  • A 2000 TBW endurance rating is substantial for a 2TB drive, pointing to a reasonable operational lifespan under regular use
  • The 5-year warranty period offers meaningful long-term coverage
  • An MTBF of 1.5 million hours reflects a solid reliability specification
  • Uses the NVMe 2.0 standard over PCIe 4.0, ensuring compatibility with modern platforms
Cons
  • Relies on HMB rather than dedicated DRAM cache, which may result in reduced consistency under sustained mixed workloads
  • No integrated heatsink, meaning thermal management depends entirely on the host system
  • Hardware-level AES encryption is not supported, which rules out use cases requiring self-encrypting drive functionality
  • Maximum operating temperature is capped at 70°C, leaving limited thermal headroom in systems with poor airflow
Who is this for?

This drive is well-suited to users who regularly move large files, such as video editors, content creators, or developers working with substantial datasets, where the 7450 MB/s sequential read and 6500 MB/s sequential write speeds translate directly into faster load and save times. The high random read rating of 1,000,000 IOPS also makes it a strong fit for demanding multitasking environments where many small operations run concurrently. With a 2000 TBW endurance rating and a 5-year warranty, it is equally appropriate for users who write data heavily over extended periods and want a drive built to last.

Who is this NOT for?

Users who require hardware-level AES encryption — such as those in security-sensitive professional or enterprise environments — will find this drive inadequate, as it offers no self-encrypting drive capability. Systems with limited cooling or poor airflow may also struggle, since the drive lacks an integrated heatsink and has a maximum operating temperature of 70°C, making it a poor match for thermally constrained builds. Additionally, workloads that demand consistent sustained performance under mixed read-write pressure may expose the limitations of HMB-based caching, which depends on host system memory rather than dedicated onboard cache.

Read speed:

sequential read speed 7450 MB/s
random read speed 1000000 IOPS

The Biwin Black Opal NV7400 2TB delivers a sequential read speed of 7450 MB/s, allowing large files to be read from the drive at a rapid pace. On the random side, it reaches 1,000,000 IOPS, reflecting strong performance when handling numerous small, scattered read operations — a scenario common in multitasking and application loading workloads.

Write speed:

sequential write speed 6500 MB/s
random write speed 900000 IOPS

The NV7400 2TB supports a sequential write speed of 6500 MB/s, enabling large volumes of data to be written to the drive at a sustained pace. For random write workloads, it is rated at 900,000 IOPS, indicating solid throughput when dealing with many small, non-contiguous write operations spread across the storage medium.

The Biwin Black Opal NV7400 2TB is an M.2 NVMe SSD operating over a PCIe 4.0 interface with NVMe 2.0 support, offering 2000GB of internal storage built on TLC NAND. It is powered by the Maxiotek MAP1602A Falcon Lite Gen4 controller with 4 channels, and relies on HMB (Host Memory Buffer) rather than dedicated onboard cache. Endurance is rated at 2000 TBW with an MTBF of 1.5 million hours, and the drive carries a 5-year warranty. The maximum operating temperature is 70°C, and it does not include an integrated heatsink, RGB lighting, or hardware-level AES encryption support.

Final Verdict

The Biwin Black Opal NV7400 2TB makes a strong case for itself as a capable PCIe 4.0 M.2 NVMe drive, with its 7450 MB/s sequential read speed and 2000 TBW endurance rating standing out as its most compelling attributes for users who prioritize throughput and longevity. Backed by NVMe 2.0 support, a 4-channel Maxiotek controller, and a 5-year warranty, it is a well-rounded option for content creators and power users who handle large workloads regularly. That said, the absence of dedicated DRAM cache, a built-in heatsink, and hardware encryption support means it is best suited to environments where those factors are not critical requirements. For users whose workloads align with its strengths, the NV7400 2TB delivers a technically solid and reliable storage solution.
