If I have a laptop with a sata 150 capability, can I use a sata 300 drive in it? I assume that it would run at sata 150 performance, but is it compatible? Would I be able to benefit from the larger cache size? Would it tend to run cooler? Any other possible benefits or drawbacks? The selection of sata 300 laptop drives is greater than the sata 150 now, and many of them offer a larger cache size (32mb instead of 16 mb). Thanks for any advice.
