Netac NV7000-Q 1TB SSD Review

We used CrystalDiskMark 8 to test the random performance of the drive at lower queue depths (QD1 – QD8 where most of the everyday workloads occur) using 1 to 4 threads.

Random Reads

In the QD1-QD8 random read tests the drive produced smooth increases in performance as the queue depth deepened without any noticeable dramas. At QD1 the drive speed ranges from 20,360 IOPS (83.39MB/s) using a single thread up to 88,901 IOPS (364.13MB/s) using four threads. At a QD of 8, the single-thread performance had increased to 160,849 IOPS (658.83MB/s) while the four-threaded test reached 491,572 IOPS (2,013MB/s).

Random Writes

In the 4K write tests, the performance rose quickly from QD1 to QD2 for all four tested threads with the fastest rise seen in the three and four-threaded tests. All four threads see the rate of increase in performance start slowing from QD2 onwards up to the end of the test run at QD8.
