OV PCIe 4.0 Pro SSD Performance Testing Results
To ensure it’s performing at its best, conducting thorough performance tests is essential. Today, we’ll explore the mainstream testing software and shed light on the significance of each test, using the OV P700 PRO SSD as our example.
1. CrystalDiskInfo (CDI)
CrystalDiskInfo, or CDI, serves as the SSD doctor, providing detailed information on health status, capacity, interface, protocol standard, and more. Pay particular attention to the number and time of power-on instances. A low count indicates a brand-new SSD. Additionally, monitor the information bar for hexadecimal details, easily switched to a more readable format by navigating to Function-Advanced Settings-Original Value-10[DEC].
2. AS SSD Benchmark
AS SSD Benchmark, or AS, offers an intuitive overview of the SSD’s continuous read and write speed, 4K random read and write performance, and a comprehensive score. Check the SSD driver status and 4K alignment, crucial for accurate performance reflection. Note that SSD drive status may vary across system platforms, and both SSD driver status and 4K alignment must show “OK” for accurate results.
3. CrystalDiskMark (CDM)
CDM covers sequential read and write, random read and write performance for different packet sizes, and 4K random performance with a queue depth of 32. Run the default 5 tests with a 1GB data volume (adjustable) to minimize data cache interference, providing more accurate results. While CDM and AS have similar interfaces, differences in test methods contribute to varied results, with CDM often yielding higher measurements due to its higher test pressure.
4. HD Tune Pro
HD Tune Pro evaluates the SLC cache size, read and write speed inside and outside the cache, and particle speed. Use [File Benchmark] to assess continuous read and write performance and SLC cache size, crucial for understanding the impact of cache size on data transfer speed. Large file tests reveal the true particle speed as the SLC cache fills.
5. ATTODiskBenchmark
ATTO, a software for setting transfer sizes, provides insight into reading and writing speeds under different circumstances. Results are presented in a clear format, offering an accurate portrayal of the SSD’s maximum reading and writing performance across various document sizes.
When interpreting results, keep in mind that small file transfers may show slower speeds compared to large files due to cache limitations. This is normal and aligns with the nominal speed of the SSD.
In conclusion, these five mainstream SSD testing tools provide a detailed understanding of your computer configuration and assist in making informed SSD purchases. Remember to back up your data during testing to prevent any potential data loss.
