Biwin Black Opal NV7400 1TB

Manufacturer: Biwin

The Biwin Black Opal NV7400 1TB is an M.2 NVMe solid-state drive built around the Maxiotek MAP1602A Falcon Lite Gen4 controller, targeting users who need fast PCIe 4.0 storage in a compact form factor. It operates without a dedicated DRAM cache, relying instead on HMB (Host Memory Buffer) technology to manage read operations efficiently while keeping the overall drive design lean.

On the performance side, the drive delivers sequential read and write speeds of 7400 MB/s and 6500 MB/s respectively, alongside random read and write throughput rated at 1,000,000 and 900,000 IOPS. It uses TLC NAND storage across a 4-channel controller configuration and carries a rated endurance of 1,000 TBW with an MTBF of 1.5 million hours. The drive has a maximum operating temperature of 70°C, does not include an integrated heatsink or hardware AES encryption support, and comes backed by a 5-year warranty.

Pros
  • Sequential read speed of 7400 MB/s and write speed of 6500 MB/s make for fast sustained data throughput in an M.2 form factor
  • Random read and write IOPS ratings of 1,000,000 and 900,000 respectively point to strong responsiveness under mixed workloads
  • A 1000 TBW endurance rating offers a solid write lifespan for a 1TB drive
  • The 5-year warranty provides meaningful long-term coverage
  • An MTBF of 1.5 million hours reflects a reliable rated operational lifespan
  • PCIe 4.0 with NVMe version 2 ensures compatibility with modern high-bandwidth platforms
Cons
  • No hardware AES encryption support, which limits data security options for users who need it
  • Relies on HMB rather than dedicated DRAM cache, which can affect consistency under sustained mixed workloads
  • No integrated heatsink included, meaning thermal management depends entirely on the host system
  • Maximum operating temperature of 70°C may require adequate case airflow in thermally constrained builds
Who is this for?

This drive suits users who need high sequential throughput for demanding storage workloads, such as video editing, large file transfers, or fast OS and application loading on a PCIe 4.0-capable system. The strong random IOPS figures also make it a reasonable fit for users running queue-intensive tasks like database access or multitasking across numerous applications. With a 1000 TBW endurance rating and a 5-year warranty, it also works well for those who write to storage frequently over long periods and want meaningful longevity coverage.

Who is this NOT for?

Users who require hardware-level AES encryption for data security compliance or sensitive environments will find this drive unsuitable, as it offers no encryption support. Those building into thermally constrained systems without adequate airflow may also face challenges, since the drive lacks an integrated heatsink and has a 70°C operating ceiling. Additionally, users relying on DRAM-cached drives for the most consistent performance under sustained, unpredictable mixed workloads may find the HMB-based caching approach less reliable in those edge scenarios.

Read speed:

sequential read speed 7400 MB/s
random read speed 1000000 IOPS

The Biwin Black Opal NV7400 1TB reaches a sequential read speed of 7400 MB/s, making large file transfers and sustained data loads move through the drive at a considerable pace. For workloads involving many small, scattered operations, the drive is rated at 1,000,000 IOPS of random read throughput, reflecting solid responsiveness under queue-heavy access patterns.

Write speed:

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

On the write side, the drive is rated for a sequential write speed of 6500 MB/s, handling large, continuous data writes at a steady and capable pace. Random write performance is specified at 900,000 IOPS, indicating the drive can process a high volume of small, non-sequential write operations without significant throughput degradation.

This is an M.2 NVMe SSD running on NVMe version 2 over PCIe 4.0, offering 1000GB of internal storage built on TLC NAND and managed by the Maxiotek MAP1602A Falcon Lite Gen4 controller with 4 channels. Rather than dedicated DRAM, it relies on HMB (Host Memory Buffer) for caching duties. The drive carries a rated endurance of 1000 TBW and an MTBF of 1.5 million hours, with a maximum operating temperature of 70°C and a 5-year warranty. It does not include an integrated heatsink, hardware AES encryption, or RGB lighting.

Final Verdict

The Biwin Black Opal NV7400 1TB is a capable PCIe 4.0 M.2 NVMe drive that delivers where throughput matters most — its 7400 MB/s sequential read speed and 1,000,000 IOPS random read rating make it a solid choice for users running modern, storage-intensive workflows on compatible platforms. Backed by a 1000 TBW endurance rating, an MTBF of 1.5 million hours, and a 5-year warranty, it offers reassuring long-term reliability for regular use. The absence of hardware AES encryption and dedicated DRAM cache do narrow its appeal for security-sensitive or highly demanding mixed-workload environments, but for mainstream power users seeking fast, durable PCIe 4.0 storage without unnecessary extras, the NV7400 1TB presents a well-rounded specification set worth considering.
