ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 64MB transfer sizes with the total length being 256MB.
Benchmark Results: On ATTO Disk Benchmark found that the Corsair MP400 1TB NVMe SSD topped out at 1.85 GB/s write and 3.23 GB/s read at the standard queue depth of 4. There were a few really low scores, but that is something we’ve seen before due to how the Phison E12S controller is handling the compression used on this benchmark.
This chart is getting pretty messy, but we are charting the 128KB results and ranking them high to low with the write result. The Corsair MP400 dropped to the lower half of the chart since the write speeds are lower than the other drives.
CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) and shows the highest score of five runs.

Benchmark Results: The Corsair MP400 1TB drive came in with scores of 3447.13 MB/s read and 1980.72 MB/s write on CrystalDiskMark 7. This drive is rated at up to 3,480 MB/s read and 1,880 MB/s write for this benchmark, so we are very close with to those numbers and are happy with the results. In order to get the drives full 3,480 MB/s read and 3,000 MB/s write speeds you need to be using the 2TB, 4TB or 8TB version and we were not sent that capacity to test.
Let’s look at some other benchmarks!
