Anti-drop hdd sensors?

[shiato storm]

whats the general feeling on these in terms of updating hdd in a MBP? looking at either seagate 7200.3 or wd scorpio (black) 320gb drives and both have a sort of sensor to detect shakes/drops etc. would this help or hinder the running of things?

oh and any idea which one my be quieter?

Since the MBP has an accelerometer built-in you want to buy drives without the sensor.

Hmm... Interesting theory there!! You know, I have WD's installed on my MBP and never had any problems with the Mac or the HD. Why not have both installed? Wouldn't the extra protection be better in the wrong run cause the Mac's built-in accelerometer would cut in at a different time to the WD's. Is there any actual evidence to say we should avoid buying drives without the sensor?

i was thinking there may be some conflict between the computer's anti-shock system and the in-hdd sensor...?

No. They are two different systems. The accelerometer in the MBP activates when it senses the MBP moving while on. This movement could be while you have it on and in your hand, not just in a free fall. The anti-shock built into most drives is specifically to protect against a free fall drop. The two do no cancel each other out. Each is self contained.

cheers, its not the cancelling out but the over-activity I was wondering about.
