I have an Asus motherboard which comes with both the AMD SB950 chipset (6 SATA ports) and also an ASMedia 1061 storage controller (2 ports).
I also have:
- 1 SSD drive for Windows
- 1 HDD for Linux
- 2 HDDs for storage
- 1 DVD drive
- 1 External HDD
That makes 5 storage units. Sometimes (somewhat often) I'll have 4 of them busy doing IO operations at the same time. Right now they're all plugged to the SB950 ports, as I read - and tested - it's faster than the ASMedia controller. However the source benchmark, as well as my testing, only covers the scenario where a single drive is being used.
Would it be advisable to re-plug some of the devices to the ASMedia controller, in order to offload the SB950 chipset?
All of the HD drives are SATA-III 7200 rpm. No RAID is used.
