Hello
I am running both types of hard drives of which you speak
the Fujitsu Mau 147 its faster than the 15K seagate cheetah U320
as far as getting to 130mbs transfer speed, that can only happen on a 64bit windows OS with a scsi controller card thats running in the PCI-X slot or PCI express X1 slot
in a 32bit windows OS running your controller in a standard PCi slot you will be downgraded to about
80.8mb/s sustained transfer speed >>>> thats still faster than any other option as far as drives go >>>>> the cheetah sustains about 66.6 mb/s
in as much as you already have the scsi set-up >>>>> I would proceed with getting the MAU 147
BTW: and U160 controller card is limited to about 80mb/s sustained transfer rate >>>>>> to get the full trottle like that fella from the hard drive place was talking about you would need an Ultra 320 capable controller card running on a 64 bit OS in the PCI-X slot
I dont believe their is such a thing as a U320 PCI slot controller card >>>> if memory serves me correctly
here is a whole slew of results
