anyone using Lacie SATA D2 drive w/PCI interface?

[kgdrum]

hi i am planning my next system(yes a G5) and i want to avoid use of fw drives if possible,i am leaning towards a fw i/o(rme fireface 800)gonna add an internal drive for samples,along with boot drive and i saw this external drive solution
LaCie 250gb 7200RPM SATA D2 Drive with PCI interface(looks pretty cool!)
1- is anyone using this w/success?
2-can you use mac drivers or do you have to use lacie's?(i have/had a lacie scsi drive that perfomed better without lacie software)until it went bad (not sure if its a bad drive or bad scsi card)adaptec 39160
I want to have a system that can work for the next 2-3 years while the intel/mac partership sorts itself out
i am trying to figure out if this is a better solution than adding a pci firewire card to keep audio hard drive on seperate fw buss than fw buss for i/o
any thought or comments?
thanks in advance
