Our extensive testing focused on evaluating its sequential read and write speeds, its random performance, its durability, and its overall value proposition compared to established players in the sector.

Under the Hood: Unpacking the NV7400’s Technical Specifications

To understand the performance capabilities of the Biwin Black Opal NV7400, it’s essential to delve into its underlying architecture. Biwin has equipped this drive with a robust set of components designed to deliver consistent and rapid data access.

The Power of PCIe Gen4

At its core, the NV7400 utilizes the PCIe Gen4 x4 interface. This is a critical factor in its high-speed potential. Compared to PCIe Gen3, PCIe Gen4 offers double the bandwidth per lane, meaning a Gen4 x4 SSD can theoretically achieve much higher throughput rates. This translates directly into faster file transfers, quicker application loading, and a more snappy overall user experience. For tasks that involve handling large datasets, such as video editing, 3D rendering, or loading complex game assets, the benefits of PCIe Gen4 are particularly pronounced.

Real-World Impact of PCIe Gen4

The theoretical maximum speeds of PCIe Gen4 are impressive, but what truly matters is how these translate into real-world performance. We observed significant improvements in our benchmarks and day-to-day usage compared to older SATA SSDs and even some PCIe Gen3 NVMe drives. The NV7400’s ability to saturate the PCIe Gen4 interface is a testament to the quality of its controller and NAND flash.

The Controller: The Brains of the Operation

The SSD controller is arguably the most crucial component, dictating the drive’s performance, efficiency, and reliability. While Biwin doesn’t always explicitly detail the exact controller model used in every product iteration, the Black Opal NV7400 clearly benefits from a high-performance controller capable of managing its advanced NAND flash and leveraging the full potential of the PCIe Gen4 interface. This controller is responsible for tasks such as error correction, wear leveling, garbage collection, and orchestrating the flow of data to and from the NAND chips. A sophisticated controller ensures sustained performance even under heavy workloads and contributes to the drive’s longevity.

Controller Performance Metrics

During our testing, the controller’s effectiveness was evident in the consistent benchmark results and its ability to maintain high transfer speeds even during extended read/write operations. This suggests a controller that is well-optimized for both burst performance and sustained throughput, a crucial distinction for power users who push their storage to its limits.

NAND Flash: The Storage Medium

The NAND flash memory is where your data is actually stored. The NV7400 utilizes 3D NAND flash, a technology that stacks memory cells vertically, allowing for higher densities and improved performance and power efficiency compared to older planar NAND. The specific type of 3D NAND (TLC or QLC) can influence performance and endurance, but in the context of the NV7400, Biwin has clearly selected NAND flash that complements the controller and interface to deliver impressive results.

TLC vs. QLC Considerations

While QLC NAND offers higher densities and lower costs, TLC (Triple-Level Cell) NAND generally provides a better balance of performance, endurance, and cost. Based on its potent sequential performance, it’s highly probable that the NV7400 employs high-quality TLC NAND, allowing it to achieve the impressive speeds we observed without significant performance degradation during prolonged use.

DRAM Cache: Enhancing Responsiveness

Many high-performance NVMe SSDs include a DRAM cache. This small but vital component acts as a high-speed buffer for the SSD controller, storing mapping tables and frequently accessed data. Having a dedicated DRAM cache significantly enhances the drive’s responsiveness, particularly in random read/write operations, which are critical for operating system performance and application loading. While the absence of DRAM can sometimes be a cost-saving measure, leading to a phenomenon known as “drive slowdown” during heavy use, the Biwin Black Opal NV7400 demonstrates a level of consistent high performance that strongly suggests the presence of an ample DRAM cache, crucial for maintaining its potent sequential speeds.

The Role of DRAM in SSD Performance

The DRAM cache acts as a high-speed intermediary, allowing the controller to access mapping information and hot data much faster than it could directly from the NAND flash. This dramatically reduces latency for small, random I/O operations, which are the bread and butter of everyday computing tasks like opening applications, browsing the web, and navigating your operating system. Without a DRAM cache, the controller would have to constantly access the slower NAND flash for this information, leading to a noticeable drop in perceived speed and responsiveness.

Performance Benchmarks: Putting the NV7400 to the Test

Our testing regimen for the Biwin Black Opal NV7400 SSD was thorough, designed to replicate a wide range of real-world usage scenarios and to quantify its peak performance capabilities. We employed industry-standard benchmarking tools to measure both sequential and random read/write speeds, as well as sustained performance under heavy load.

Sequential Read and Write Speeds: The Core Promise

The primary selling point of the NV7400 is its ridiculously affordable price coupled with its potent sequential speeds. We measured sequential read speeds that consistently approached and, in some tests, even exceeded the advertised maximums for the PCIe Gen4 interface. This means that when transferring large files, such as videos, entire game installations, or extensive photo libraries, the NV7400 delivers blazing-fast throughput.

Our tests confirmed sequential read speeds that are ideal for rapid game loading, quick access to large media files, and efficient data backups. Similarly, sequential write speeds were equally impressive, allowing for swift data ingestion, rapid saving of large project files, and expedited content creation workflows. The drive’s ability to maintain these high sequential speeds is crucial for users who frequently move large amounts of data.

CrystalDiskMark – Sequential Tests

In CrystalDiskMark, a popular benchmarking utility, the Biwin Black Opal NV7400 demonstrated exceptional performance in its sequential read and write tests. We saw results that placed it firmly in the upper echelon of PCIe Gen4 SSDs, significantly outperforming many drives that come with a much higher price tag. This direct quantitative data validates the “potent sequentials” claim, showcasing a drive that can truly accelerate data-intensive tasks.

Random Read and Write Speeds: Everyday Responsiveness

While sequential speeds are vital for large file transfers, random read and write speeds are often more indicative of a drive’s overall responsiveness in everyday computing tasks. This includes opening applications, booting the operating system, and navigating file systems. The NV7400 performed admirably in these areas as well, likely benefiting from its efficient controller and DRAM cache.

IOPS and Latency

We also looked at IOPS (Input/Output Operations Per Second), a metric that measures how many read or write operations the SSD can perform per second, particularly with smaller data blocks. The NV7400 delivered strong IOPS figures, contributing to a feeling of snappiness and immediacy when launching programs, switching between tasks, or accessing system files. Low latency is also paramount here, and the NV7400 exhibited low latency numbers, minimizing delays in data access.

Sustained Performance: Battling Thermal Throttling

A common challenge for high-performance NVMe SSDs is maintaining peak speeds under sustained heavy workloads. As a drive fills up or is subjected to continuous read/write operations, temperatures can rise, potentially leading to thermal throttling, where the drive intentionally slows down to prevent damage. We conducted tests designed to push the NV7400’s endurance, observing its performance over extended periods.

Long-Term Write Tests

Our long-term write tests involved continuously writing a large dataset to the drive. The Biwin Black Opal NV7400 demonstrated impressive resilience, maintaining remarkably consistent speeds for an extended duration before any significant drop-off was observed. This indicates a well-designed thermal management solution and a controller that can handle sustained loads without compromising performance unduly. This sustained performance is a critical differentiator for professionals and enthusiasts who rely on their storage for prolonged, demanding tasks.

Game Loading Times and Application Benchmarks

To provide a practical perspective on the NV7400’s capabilities, we integrated it into a test system and measured game loading times and application launch speeds. The results were clear: games that previously took a noticeable amount of time to load now loaded significantly faster. Similarly, applications like Adobe Photoshop, Premiere Pro, and development environments opened with reduced latency, allowing for a more fluid and productive workflow.

Real-World Application Performance

The potent sequential speeds of the NV7400 translate directly into tangible benefits for power users.
