I currently have a SATA 150 drive running on a SATA 150 interface and would like to purchase a new HD. My questions is, would I be able to run a SATA 3.0 drive on my SATA 150 interface? In the future, it would allow me to keep the newer drive without having to upgrade, again.
Yes they are compatable. SATA II drives have a jumper that comes enabled for 1.5 ghz of SATAI. If you get a SATA II pci-e card or compatible mobo then just remove the jumper to enable the faster speed.
Good luck. Also check out the new perpendicular drives for even more speed and size.
I agree - they'll run. Not all drives have a jumper though - I have 6 of the HDS 250GB sata drives, 4@ 150 and 2@ 3.0 - no jumpers. (I looked - I thought I'd missed something) Some high end controllers will even display the speed of the drives.
