Hi Kurt,

I have purchased a 300 GB SSD and a PCI-e Disk Controller.

I am still in the planning stage as to how to set this up.

My initial ideas are to:

• Leave the SSD on the motherboard Disk Controller
• Connect the Platter Hard Drives to the PCI-e Disk Controller
  
• Send the initial capture files to be stored on the SSD
• Use RSync to move the files from the SSD to the Platter Hard Drives ( --remove-source-files )
  (this is required as I am receiving 1.5 TB a day and the SSD is only 300 GB)

• Investigate limiting the Bandwidth of RSync to reduce contention on the Platter Drives if required.

Thoughts?

Thanks for the heads up - I have obtained a 300 G SSD that I will
experiment with.

I will let you know if I find the same result.

I'm just curious. What are your results with the SSD?

BTW: did you try to 'ionice' dumpcap?

Cheers
Kurt
