Ehlo, you can change the behaviour of the cache flush by changing 'sysctl -w vm.laptop_mode=1' so the kernel doesn't flush cache to disk so often... and with hdparm -M xxx you can change acoustic management.... keep in mind that you can loose data if you don't flush cache and power goes off.. cheers
