Iometer: 4kB random read/write
We used Iometer to measure the random read speed using 4k data blocks at queue depths of 1 through 32. The NX500 has an average score at a queue depth of 1 and is a lot slower than the 960 Pro. This discrepancy is less at a queue depth of 32, where the NX500 manages to get a lot closer to the 960 Pro; thereby being faster than a lot of other SSDs.
The write speed of the NX500 is not amazing. In the QD1-test it turns out to be one of the slowest, but in the QD32-test it manages to secure a spot in the middle of the pack.
