IOMeter has to be one of the most widely used software packages for benchmarking disks. There are an endless number of ways you can build a benchmark, but we chose to limit our benchmarking to 100 percent Sequential Read and Write then 100 percent Random Read and Write. You can emulate our benchmarking by using the following configuration
‘size | % of size | % reads | % writes | % sequential | % random | delay | burst | align | reply |
2,097,152 | 100 | 100 | 0 | 100 | 0 | 0 | 1 | 0 | 0 |
2,097,152 | 100 | 0 | 100 | 100 | 0 | 0 | 1 | 0 | 0 |
2,097,152 | 100 | 100 | 0 | 0 | 100 | 0 | 1 | 0 | 0 |
2,097,152 | 100 | 0 | 100 | 0 | 100 | 0 | 1 | 0 | 0 |
IOMeter’s sequential benchmark shows again that the M4 is capable of meeting 500MB/s read and over 200MB’s write.
