Two PNY M.2 CS3040 SSD disks under RAID-0 configuration reach 11 GB/s speed

Raid-0 system

In previous articles, we have demonstrated that new PNY M.2 CS3040 SSD disk reached a speed of 5.600 MB/s as established in specifications. Our benchmark showed this 2TB model can truly achieve this impressive reading speed with 3 different samples. But we wanted to go further and faced another challenge: we have tested the speed of two M.2 SSD disks in a RAID-0 system configuration to see if the speed can really double.

In order to test it, we have configured this system and analysed the READ and WRITE speed with the same sample sizes as in the other benchmark: 10 MB, 100 MB and 1.000 MB (1 TB) file size. In this case, also blue line is the READ speed and red line is WRITE speed.

Benchmark test RAID-0 system

Read / Write benchmark for 10 samples of 1.000 Mb (1GB)

Average Read Rate: 10 GB/s (vs. 5.2 GB/s with one disk)

Average Write Rate: 5,6 GB/s (vs. 3.6 GB/s with one disk)

Benchmark test RAID-0 system

Read / Write benchmark for 100 samples of 1.000 Mb (1GB)

Average Read Rate: 10,6 GB/s (vs. 5.2 GB/s with one disk)

Average Write Rate: 7,8 GB/s (vs. 3.6 GB/s with one disk)

Benchmark test RAID-0 system

Read / Write benchmark for 1.000 samples of 1.000 Mb (1GB)

Average Read Rate: 10,9 GB/s (vs. 5.5 GB/s with one disk)

Average Write Rate: 8 GB/s (vs. 4.2 GB/s with one disk)

Results are clear: the system almost double the speed of the M2 SSD disk alone. While READ rates are between 5 and 6 GB/s with only one M2 SSD disk, this benchmark shows the speed with RAID-0 is much faster, even up to 10,9 GB/s when using 1.000 MB file size. The same has occurred for WRITE rates: our tests reveals that average speed is about double comparing with one-disk benchmark results.
