The AS SSD test is a benchmarking tool specifically designed for SSDs. It measures different performance metrics to evaluate the speed and efficiency of an SSD. By simulating real-world usage scenarios, the AS SSD test provides comprehensive data that helps users assess an SSD’s performance in specific areas.

Importance of AS SSD test data

Understanding AS SSD test data is crucial for several reasons. Firstly, it enables users to make informed decisions when choosing an SSD for their specific needs. By comparing the test results of different SSDs, users can identify the best-performing drives that align with their requirements. Secondly, AS SSD test data helps users optimize their SSD’s performance by identifying potential bottlenecks or issues. By addressing these concerns, users can enhance their system’s overall performance.

Understanding Sequential Read and Write Speeds

Sequential Read and Write speeds are essential indicators of an SSD’s ability to transfer large files quickly. Higher sequential speeds result in faster data transfer, leading to improved performance. When examining the AS SSD test data, focus on the Sequential Read and Write speeds and compare them across different SSDs to determine their relative performance.

Interpreting 4K Read and Write speeds

The 4K Read and Write speeds measure an SSD’s performance when dealing with small files and random data access. These speeds are especially crucial for tasks that involve numerous small files, such as booting the operating system or launching applications. Higher 4K Read and Write speeds indicate better performance in these scenarios. Analyzing the AS SSD test data, pay attention to the 4K Read and Write speeds to assess an SSD’s responsiveness in real-world usage.

Analyzing Access Time

Access Time refers to the time it takes for an SSD to locate and retrieve data. It is a critical metric for overall system responsiveness. Lower access time values indicate faster data retrieval, resulting in quicker application launches and file access. When reviewing the AS SSD test data, focus on the Access Time values and compare them to determine which SSD offers better responsiveness.

Explaining IOPS (Input/Output Operations Per Second)

IOPS, or Input/Output Operations Per Second, represents the number of reads and write operations an SSD can perform in a second. Higher IOPS values indicate better performance, particularly in tasks that involve frequent data access, such as gaming or video editing. Assessing the AS SSD test data, consider the IOPS values to understand an SSD’s capability to handle intensive workloads effectively.

Evaluating the Score

The AS SSD test assigns an overall score to each SSD based on its performance in various metrics. This score provides a quick summary of the SSD’s performance and can be helpful for comparing different drives. However, it is important to note that the score should not be the sole factor in decision-making. It is essential to examine individual performance metrics in detail to gain a comprehensive understanding.

Factors Influencing AS SSD Test Results

Several factors can impact AS SSD test results. One crucial factor is the SSD’s firmware version. Manufacturers often release firmware updates to address performance issues and improve compatibility. Keeping the firmware up to date ensures accurate and reliable test results. Additionally, the system configuration, such as the motherboard and storage controller, can influence performance. It is recommended to use the latest drivers and ensure the system is properly optimized.

[Real Example] Comparing AS SSD Test Data Across SSDs

When comparing AS SSD test data across different SSDs, it is important to consider the specific requirements of your use case. Some SSDs may excel in sequential read and write speeds, while others may perform better in random access scenarios. By aligning the test results with your intended usage, you can identify the SSD that offers the best performance for your specific needs.

AS-SSD-MB

Based on the test results shown in the above figure, let’s analyze it as an example.

AS SSD’s benchmark score is divided into four groups of read and write. The test data can be set to 1G, 3G, 5G, or 10G and then a score is given. Usually, the default test is set to 1G.

Seq refers to the continuous read and writes speed, measured in 16MB units. The test involves writing a 1GB file continuously, followed by reading the same file and calculating the average score of both operations.

4K refers to random read and write speeds for files with a size of 4KB. SSDs have an advantage over mechanical hard drives in quickly accessing these small DLL files, which improves disk performance without causing any lag.

The test involves generating a 1GB file in units of 512KB and performing random read/write tests at specified locations using units of 4KB until the entire range is covered. The average score is then calculated to obtain the test result.

4K-64Thrd refers to the speed of concurrent reads/writes on multiple threads for files with a size of 4KB per thread (64 threads are used). This test is used to evaluate multi-threaded performance.

The test involves generating sixty-four testing files each with a size of sixteen MB (totaling one GB) and performing simultaneous read/write tests on all sixty-four files using units of four KB per thread. The average score is then calculated to obtain the test result.

Acc.Time refers to access time or how long it takes for the head assembly to find its target track on a magnetic disk drive; this includes how long it takes for sectors that need reading/writing from mechanical hard disks’ rotation position under their respective heads on average.

Score represents overall performance evaluation based on scores assigned during testing.

In summary, sequential read/write speed and random read/write speed at sizes around four kilobytes are important metrics when evaluating SSDs’ daily use cases while larger queue depths like QD64 are more relevant when assessing server-level SSD performance.

Due to the fact that manufacturers know that users value continuous read and write performance, in order to “perform well” in benchmarking software such as AS SSD Benchmark, they will force a portion of the capacity to run SLC speed in the first 1G or 3G of the controller. Since SLC speed is the fastest among all speeds, data tested within the first 1G or 5G will look good, but speeds will slow down significantly after 5G, 10G, or even 20G. Therefore, when testing it is important to consider overall performance.

On the other hand, in daily life, continuous reading and writing speeds are like driving at high speeds with a maximum speed of up to 100km/hour. However, it’s not possible to always drive at high speeds in everyday life due to traffic jams and frequent stops. Therefore, it’s mainly important to focus on random access performance (4K).
