CrystalDiskMark is a useful benchmark to measure the theoretical performance levels of hard drives and SSDs. We are using v8.0.
The Netac's NV7000-t read score of 82.78MB/s in CrystalDiskMark 8's 4K QD1 test sees it in the top ten of our results chart. However, its write score of 318.80MB/s is the second fastest we've seen in this test for a Gen 4 drive to date.
Looking at the benchmark result screens we can confirm the official Sequential read rating of 7,300MB/s and even better it a little with a test result of 7,437MB/s. However, when it came to Sequential writes our test result score of 6.485MB/s is somewhat short of the official maximum of 6,700MB/s. The controller in the drive seems happier dealing with compressible data when it comes to reading 4K data as can be seen by the 0 fill result screen for QD1 T1 and QD32 T16. On the flip side the 4K QD32 T16 write performance dropped when using compressible data.
The NV7000-t's Sequential read test result of 7,437MB/s puts the drive into sixth place on our results table.
Peak Performance Profile
Netac quotes 4K random performance figures for the NV7000-t of up to 900,000 IOS for reads and up to 700,000 IOPs for writes. When tested with the Peak Performance profile test in CrystalDiskMark8 we could confirm those figures and indeed better them. The best read score we saw was 947,658 IOPS while the best write result, 1,081,518 IOPS soared past the official figure.
As with the default test, we could confirm the official Sequential read performance figure but not the writes. Swapping over to compressible data saw 4K random reads rise to 1,099,592 IOPS while writes went in the opposite direction dropping to 794,072 IOPS, both figures topping the official ones.
Real World Profile
In the Real World profiles test the drives Sequential read result of 5,109MB/s sees it third place in our results chart behind Crucial's T500 and WD's Black SN850X Heatsink drive.
