Low g Accelerometer as a high frequency vibration sensor

Is there an accelerometer in Freescale/NXP's low g series which can do high frequency vibration detection. I'm looking for something to mount on server hard drives (7200RPM - 12000 RPM) and the server chassis (for fans running between 0 - 24000RPM) which would provide continuous vibration reading (so I could dynamically set the threshold). I'd be using something like the MK20DX256VLH7 to interface with the sensor. Currently I'm trying to do this with an Arduino using a piezoelectric based vibration sensor. But you can't adjust those thresholds dynamically. I'd appreciate your help and suggestions on what product to use, and the best way to go about implementing it.


Thank you and best regards,
