Throughput Benchmarks (SEQ and RND)
CrystalDiskMark
We are using CrystalDiskMark to benchmark the sequential and random throughput of read and write performance. For these NVMe SSDs, we are using the NVMe profile in CrystalDiskMark. This tests SEQ1M Q8T1, SEQ128K Q32T1, RND4K Q32T16, and RND4K Q1T1.
The Biwin Black Opal NV7400 2TB SSD has a rated sequential read speed of up to 7,450MB/s and a rated sequential write speed of 6,500MB/s on paper. In our CrystalDiskMark testing, we can see that it is hitting the maximum sequential read speed, within margin, at 7,412MB/s, and it is actually exceeding the write speed at 6,654MB/s. This is a very solid performance, and shows that it is hitting its potential, and maybe even a bit better on write performance. There is not a lot that separates the Biwin Black Opal NV7400 2TB SSD on read performance compared to the highest performing SSDs on this graph. Even on write performance, it is only a 266MB/s difference compared to the fastest drive, the Samsung 990 PRO. The Biwin Black Opal NV7400 2TB SSD surely beats many of the other SSDs on the graph.
Again, in SEQ128K Q32T1, the trend continues for the Biwin Black Opal NV7400 2TB SSD, and it holds its own at high performance, coming within a couple of hundred MB/s on write compared to the fastest SSDs.
In RND4K Q32T16 testing, we have sorted the graph by write performance to emphasize the strength of the Biwin Black Opal NV7400 2TB SSD. The Biwin Black Opal NV7400 2TB SSD has a very solid random write performance, above the average here, delivering 4,461MB/s. There are some faster drives, but again, we see the common drives we’ve come to expect for that performance up there on the chart. The Biwin Black Opal NV7400 2TB SSD at 3,973MB/s read is also above many drives.
If there is one weakness, it is in RND4K Q1T1 testing. The Biwin Black Opal NV7400 2TB SSD provides 69MB/s of random read performance for RND4K Q1T1 testing, and this puts it toward the lower end of performance, closer to the Acer FA200 and Netac NV7000. However, looking at the write performance, it is down at 219MB/s, which is the slowest drive on the graph for that metric.
ATTO
Using the popular ATTO Disk Benchmark, the Biwin Black Opal NV7400 2TB SSD sits at 6.92GB/s read and 6.17GB/s write. The Biwin Black Opal NV7400 2TB SSD is below the average on read, but write performance is not the worst, and above the average.
