Netac NV7000-t 2TB 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 random read QD1-QD8 tests the drive produced smooth increases in performance as the queue depth deepened without any noticeable dramas. At QD1 the drive speed ranges from 20,216 IOPS (82MB/s) using a single thread up to 87,623 IOPS (358MB/s) using four threads. At a QD of 8, the single-thread performance had increased to 161,889 IOPS (663MB/s) while the four-threaded test reached 498,442 IOPS (2,041MB/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. QD1 performance ranges from 71,117 IOPS (315MB/s) using a single thread up to 256,807 IOPS (1,051MB/s) using four threads.
