Using the CrystalDiskMark software, the SAMSUNG 990 PRO 1TB was tested under an empty disk state to measure its read and write performance. The test file size was set to 1 GiB by default, yielding read and write speeds of 7131.79 MB/s and 6811.64 MB/s, respectively.

The Q8T1 result displayed in the first column indicates a situation where one thread has eight queue depths, meaning that there are eight 1 MB access items in the task list awaiting completion. This scenario corresponds to the real-world instance of simultaneously reading from or writing to eight different 1 MB files on the hard drive. However, it should be noted that such operations are generally infrequent.

For everyday usage scenarios or for gamers, the range of items from QD1 to QD4 could be more relevant. Adjusting the CrystalDiskMark configuration file to assess real-world performance results in the first column changing to Q1T1. While the output might be slightly lower than Q8T1, the outcomes are more representative of the performance in typical daily usage.

This is because Q1T1, which indicates a single thread handling one queue depth, is the mode that operating systems commonly use in most daily operations. Hence, Q1T1 is more applicable for everyday usage compared to Q8T1. When testing in Q1T1 mode with the test file size set to 1 GiB, the recorded read and write speeds were 4246.31 MB/s and 5977.06 MB/s, respectively.

AIDA64’s Linear Read and Linear Write tests conduct full-disk read and write tests with MAX-capacity files, providing users the opportunity to monitor the stability of their reads and writes. The Linear Read test revealed a stable average read rate of 5897.6 MB/s for the hard drive.

During the Linear Write test, the SAMSUNG 990 PRO 1TB’s cache was depleted when it reached the 12% mark, leading to a drop in the write speed to a minimum of 403.3 MB/s. However, it bounced back to around 5500 MB/s after a 5% progress and continued to repeat this pattern until the end. The overall average write speed was 4559.5 MB/s. Therefore, if a user is writing a large file of approximately 120 GB at once, the SAMSUNG 990 PRO 1TB will require some buffering time to restore its original write speed performance.
