I just installed a new SataII drive last night - samsung spinpoint 1tb.
the bios is set to AHCI and all drives are UDMA 6, but ...
my os drive sataII to existing sataI drive copies at a burst of 120mb/s and settles to 80mb/s.
my os drive sataII to the new sataII samsung drive copies with no burst at a constant rate of also 80mb/s.
should I be setting something else to get the burst mode on the new drive?
all drives have the tickbox set for the enable write caching, but not 'Enable advanced performance'
I can see no OS differences between the new and the other drives (1x sataII and 2xsataI)
