    There aren't any notebooks on the market today that can take advantage of the 3.0 g/b throughput. Go with which ever is cheaper.

    Drives put out data at about 30-80MB/sec (depending on the drive, older is slower).

    The SATA interface can handle ~150MB/sec at the SATA 1.5 speeds, and double that at the 3.0 speeds.

    So a single drive on a SATA interface will see NO benefit today from the 3 vs 1.5

    Yes, there can be a difference if the data is in the buffer (aka cache) on the drive. But unless you are planning on reading and writing to the same couple of MB all day long, the theoretical speed will make no difference to you.

    rpm is usually more important than SATA 150 or 300. go w/ 7200rpm

    3 of my SATA drives are 150mbps, 1 is 300mbps. I notice zero difference in speed.
