Performance in Intel IOMeter Sequential Read and Write Patterns
In order to provide you with extensive testing results, we also checked how fast they can handle sequential reading and writing when the array processes ordered requests with linearly growing address. The results are provided in the tables below and on 4 graphs built for both types of RAID arrays considered.
Let’s start with reading:
In RAID 0 array we see that VIA VT8237 controller appears better than the rivals when we process small data blocks. This advantage is achieved while the CPU bears really intensive workload, but this makes VIA solution the winner anyway. Both Intel controllers perform almost equally fast, while SiS964 appeared the slowest of all.
