CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSDs. We are using v8.0.5.
Netac's NV7000-Q read score of 83.97MB/s in CrystalDiskMark 8's 4K QD1 test sees it in the top five of our results chart. However, its write score of 309.59MB/s is the fastest we've seen in this test for a 1TB class Gen 4 drive to date.
A glance at the benchmark result screens confirms the official Sequential read/write performance figures of up to 7,100MB/s and 6,200MB/s respectively with a default read test result of 7,229MB/s with writes at 6,216MB/s. The controller in the drive seems happier dealing with compressible data when it comes to reading 4K data at QD1 as can be seen by the 0 fill result screen for QD1 T1, 205.63MB/s compared to 83.97MB/s.
The NV7000-Q's Sequential read test result of 7,229MB/s puts the drive into third place on our results table with the second-best write score to date (for a 1TB class drive) of 6,216MB/s.
Peak Performance Profile.
We couldn't find an official 4K rating for the drive but the controller is rated up to 1,000,000 IOPS for both reads and writes. When tested with the Peak Performance profile test in CrystalDiskMark8 we could confirm the maximum read figure with a test result of 1,066,698 IOPS. Tested write performance on the other hand came up short with a best result of 896,142 IOPS.
As with the default test, we could confirm the official maximum Sequential read performance figure but not the writes with test results of 7,196MB/s and 6,082MB/s respectively.
Real World Profile.
In the Real World profiles test the drive's Sequential read result of 5,321MB/s sees it top the performance charts. Its write result of 5,844MB/s is also the fastest we've seen to date for a 1TB class Gen. 4 drive
