Software features
Professionalism and pertinence
Focus on SSD testing, covering core indicators such as sequential read and write, 4K random read and write, access time, etc. It is especially suitable for evaluating SSD performance with different interfaces such as NVMe and SATA.
Provides a "compression algorithm" test mode to simulate the transmission scenario of compressible data (such as operating system files) and reflect the performance of SSD in actual use.
Free and lightweight
It is completely free, with no advertisements or paid function restrictions. The software size is only about 260KB. No installation is required, and it can be run after decompression.
Supports direct downloading from the official website, or obtaining the latest version (such as v2.0.7316.34247) through reliable platforms such as Tencent Software Center.
Intuitive scoring system
Generate a total score (Score) and sub-scores (Seq, 4K, Acc.Time, etc.). A total score of more than 1,000 usually indicates good performance, but it needs to be judged based on the hard disk type (SATA/NVMe).
Provides "Copy Benchmark" function to simulate actual file copy speed (such as ISO, program, game files), which is closer to daily usage scenarios.
Hardware information display
Displays the SSD's firmware version, serial number, drive health status (via S.M.A.R.T. data) and partition format (such as NTFS/exFAT) to assist in troubleshooting hardware problems.
Software function
Core test items
Sequential read and write (Seq): Tests the maximum speed (MB/s) of continuous reading and writing of large files, reflecting the theoretical peak performance of SSD.
4K random read and write: evaluates the random access capability of small files (4KB), which directly affects the system response speed (such as booting and application startup).
4K-64Thrd multi-thread test: simulates 4K random write performance in high concurrency scenarios, which is crucial for server or multi-tasking scenarios.
Access time (Acc.Time): Measures the delay (milliseconds) for the hard disk to locate the file and start reading and writing. The lower the value, the better.
Accessibility
TRIM verification: Check whether the TRIM function (optimized garbage collection) is enabled on the SSD to ensure that performance does not decrease after long-term use.
Language switching: supports multiple languages (including Chinese) to adapt to different user needs.
Result export: Save the test report as a picture or text file to facilitate comparison and analysis.
Features
Comparison mode: Test two hard drives at the same time to visually compare performance differences (such as when replacing old and new SSDs).
Stress test: Test the stability and heat dissipation performance of the SSD through long-term high load testing.
FAQ
Test results fluctuate greatly
Question: The same hard drive was tested multiple times and the scores were significantly different.
Solution: Close background power-consuming programs (such as anti-virus software, download tools) to ensure that the hard drive is idle during the test; update the SSD firmware to the latest version.
