    I currently have the seagate 7200.4 500gb but i noticed my load cycle count is already at 8000 after only 3 weeks of use. So I think Im going with the hitachi 7k500. does anyone know if this has the g sensor built in? if so does this interfere with my macbooks g sensor?

    I don't know about the G sensor.

    You can't always trust the numerical values for SMART info, nor can you trust that it is correctly labeled. A lot of fields are manufacturer-specific or not required by the standard. As long as you aren't hearing the drive spinning up and stopping all the time and the computer is working normally (not lagging or beachballing), you are probably fine. It would have to happen every 30 seconds nonstop to get 8000 cycles in 3 weeks.

    Please refrain from bumping threads (especially within a few hours).

    Seagate drives will have model numbers as such:

    xxxxxxx......AS

    or

    xxxxxxxxx.....ASG

    If it ends in G, it has a sensor. Yes, the sensor interferes with the Mac's sensor and you should find a way to disable one or the other.

    Either way, look up your model number on Google to find out.

    ^^ Not a seagate, therefore different naming conventions.

    The OP, it's not unreasonable for you to just google '7k500' and go to the manufacturer's website for that drive.

    (btw, it doesn't have a G-sensor)

    My bad. I saw "Seagate" somewhere in there and I guess I missed the "Hitachi" part. ;)

    If someone can help me with this: I remember there was a thread here trying to figure out how to reduce OS X copious usage of load cycles.

    I'm pretty sure mine looks bad, but my old drive was worse (iirc):

    So far 3.5 months of ownership, 2490 hours and 242000 load cycles.

    Changed this a little, no offense intended, as the OP stated he (currently) has the Seagate and wants to switch to a Hitachi, which is his choice, but I would assume the two drives are very close in terms of performance, etc. I have heard good things about the Hitachi drive, quiet, fast and low battery drain, but the Seagate in my MacBook Pro is also quiet, fast, has no perceptible vibration, and the battery drain is only a little greater than the stock 250GB Toshiba.
