Hi guys,

I'm a newbie so please be patient.

I am trying to determine the cost drivers of ide hard drives. What are the
different components and their cost contribution? The end game is to
determine the bottom cost of a drive if
performance and density constraints can be relaxed (i.e. the lowest cost to
manufacture a "small, slow drive".)

Cost drivers identified so far are:
    1. # of platters
    2. # of heads
    3. Embedded servo vs. dedicated servo
    4. Spindle motor speed
    5. Onboard logic (don't know if this is variable cost i.e. can use
cheaper DSPs/controllers)

Don't know the percentage contribution, nor absolute numbers for these as
relates to HDD cost. Hard numbers would be greatly appreciated.

I'm sure this has been discussed previously so I apologise in advance for
wasting b/w.

Thanks,
Anupam
