CrystalDiskMark is a useful benchmark to measure the theoretical performance levels of hard drives and SSDs. We are using v8.0.
Corsair's MP700 Elite with Heatsink 2TB performs well in the CrystalDiskMark 8 4K QD1 T1 test, with a very good read score of 89.41MB/s but the thing that stands out is the write result of 346.43MB/s which is just shy of the fastest write performance we've seen in this test to date, which was from the reference Phison E31T drive.
As you can see from the benchmarking screens we can confirm the official sequential ratings of the drive of up to 10,000MB/s for reads and up to 8,500MB/s for writes and better them a little with default test figures of 10,391.10MB/s for reads and 8,757.61MB/s for writes.
That 10,391.10MB/s read result sees the MP700 Elite with Heatsink leading a bunch of 10GB/s drives although its write performance is nowhere near as good.
Peak Performance Profile
We can confirm the official random 4K figures for the drive of up to 1,300,000 IOPS for reads and up to 1,500,000 IOPS for writes using the Peak Performance profile of CrystalDiskMark 8 with default test results of 1,375,484 IOPS for reads and 1,511,591 IOPS for writes.
Once again we could confirm the official sequential figures with test results of 10,392MB/s for reads and 8,767MB/s for writes.
Real World Profile
The Corsair MP700 Elite with Heatsink sits above the reference design E31T in the CrystalDiskMark 8 Real World result table with a read score of 5,622MB but its write performance at 8,780MB/s is better.
