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) ( http://www.cyberciti.biz/tips/linux-use-rsync-transfer-mirror-files-directories.html ) ( http://www.cyberciti.biz/faq/linux-unix-bsd-appleosx-rsync-delete-file-after-transfer/ ) ( http://unix.stackexchange.com/questions/12198/preserve-the-permissions-with-rsync ) ( http://stackoverflow.com/questions/9586798/rsync-over-ssh-preserve-ownership-only-for-www-data-owned-files ) (http://www.comentum.com/rsync.html) - Investigate limiting the Bandwidth of RSync to reduce contention on the Platter Drives if required. (http://www.cyberciti.biz/faq/throttle-disk-io-rate-limit-disk-io/) Thoughts? -John On Wed, Jan 9, 2013 at 6:48 PM, <ws.dev.list () nospam knochner com> wrote:

What are your results with the SSD? BTW: did you try to 'ionice' dumpcap?
