Raid 0 using internal and external hardrive - possible??

Is it possible to use an e-sata port to connect a HDD externally for use in a raid setup. Just have a 160gb 5400rpm HDD lying around and wanted to know my options. If I set up raid 1 would I always have to have the external HDD connected to run?

Thanks

 

I'm not sure if it's physically possible, but why in gods name would you want to? In a RAID 0 setup your laptop would be useless unless you ALWAYS had the second HDD dangling on the cable. In RAID 1 you shouldn't need the second drive for the system to boot, but when you use your computer you are bound to make changes to the file structure that would not be reflected if the second drive was not connected. IF it did work you would still need to allocate time for the computer to figure out how you changed your drives contents between the times that it was connected.

 

raid 0 will be a bad idea, because even if the external was running through usb, it would run at the same data bandwidth of the internal harddrive. Also you need the same size discs to do a raid 0 installation. Most raid managers are picky, and will only work with two identical drives.
Their really is no point of using RAID 0 because almost all laptops have a software based raid controller. So the most you will see is around a 5-10% performance increase.
I dont think your c90 has any raid options, so you will not be able to even create a raid installation.
