Pros
- Sequential read speeds reach 7450MB/s and write speeds hit 6500MB/s, making it quick for large file transfers.
- Equipped with a 0.5mm graphene aluminum heat sink, it manages heat effectively to maintain stable performance.
- Utilizes 3D TLC NAND and a Maxiotek MAP1602A controller, offering a solid foundation for performance.
- Includes Biwin Intelligence software for drive management, performance testing, and firmware updates.
- Features PMIC power management for improved power efficiency and extended drive durability.
- Offers a 5-year limited warranty and 1000TBW endurance for the 1TB model.
Cons
- It's a DRAM-less SSD, relying on Host Memory Buffer (HMB), which might impact sustained heavy workloads compared to drives with dedicated DRAM.
- BIWIN isn't a widely recognized brand, leading to some user uncertainty about long-term reliability.
- Some users have reported difficulty finding it readily available in all regions.
Dimension Scores
With 7450MB/s read and 6500MB/s write, it's at the higher end of PCIe Gen4 speeds, providing fast data transfer.
The 5-year warranty, 1000TBW endurance, 3D TLC NAND, and PMIC power management suggest a focus on durability, though the DRAM-less design could be a minor factor for extreme use cases.
1TB is a common and practical capacity for a primary drive or a significant game library, balancing cost and storage needs for most users.
Its M.2 2280 form factor and PCIe 4.0 interface make it widely compatible with modern desktops, laptops, and the PS5.
Best For
- Gaming PCs needing faster game load times and smoother asset streaming.
- Laptops or desktops requiring a significant speed upgrade for daily tasks and application launches.
- PS5 storage expansion for installing more games and reducing load screens.
- Users on a budget who want near top-tier PCIe 4.0 speeds without the premium price of DRAM-equipped drives.
Not Recommended For
- Professionals performing extremely heavy, sustained write operations where a dedicated DRAM cache is critical.
- Users who prioritize established, well-known brands above all else for peace of mind.
Watch Out For
- The DRAM-less design, while offset by HMB, means it might not maintain peak performance during prolonged, intensive data transfers or database operations.
- Some users express hesitation due to BIWIN being a less familiar brand in the SSD market, questioning its long-term support.
- While it includes a graphene heat sink, some users might still opt for an aftermarket heatsink for extreme thermal environments, especially in compact systems.

What Buyers Say
This BIWIN Black Opal NV7400 SSD often gets attention because it's a DRAM-less drive that still manages to hit really high PCIe 4.0 speeds. People are generally surprised by how fast it is for the price, especially considering it uses Host Memory Buffer instead of dedicated DRAM. The included graphene heatsink is a nice touch, helping keep temperatures in check, which is crucial for sustained performance. While some users are a bit wary of the BIWIN brand since it's not as established, the performance numbers speak for themselves in many real-world scenarios.
“Dude, I was skeptical about this 'Biwin' thing, but for the price, this SSD absolutely flies! My games load so much faster on my PC, and it was a breeze to install in my PS5. Totally worth it, even if I never heard of them before. My only gripe is I wish I bought the 2TB version.”
Common Praise
- Sequential read speeds consistently hit near 7450MB/s in benchmarks, making file transfers quick.
- The included 0.5mm graphene heatsink keeps the drive running cool, even under load.
- It works perfectly as a PS5 storage expansion, significantly reducing game load times.
- The price-to-performance ratio is really competitive for a PCIe Gen4 drive.
- Biwin Intelligence software provides useful tools for monitoring and managing the drive.
Common Complaints
- Some users are hesitant about the brand's long-term reliability compared to more established manufacturers.
- The DRAM-less design, while performing well, raises questions for those needing absolute peak sustained performance for professional tasks.
- Availability can be inconsistent in certain markets, making it harder to purchase.
Ownership Tips
- The graphene heatsink is thin enough that it usually fits under motherboard heatsinks without issue.
- Performance remains consistent even after filling the drive past 70% capacity, which is a pleasant surprise for a DRAM-less model.
- The Biwin Intelligence software is basic but functional for checking drive health and updating firmware.
- It runs noticeably cooler than my previous Gen3 NVMe drive, even without an active cooler.
- Installation was straightforward, and the drive was immediately recognized by both Windows and the PS5.
