I m considering relpacing my HP TC4200 internal disk.
I am undecided whether buying a 7200 rmp and 16 mb cache internal disk.
Would that really improve performance? How would that disk cost in terms of
energy absorption and heating with respect to the 5400 rpm disks?

Thank you

A faster-spinning disk will improve latency delays which helps a bit but
the computer itself is pretty slow to begin with. As for power consumption,
that is impossible to estimate unless the exact type of the old and
proposed new drive are known. Heat may be a problem; does the area of the
drive get overly warm now? A bigger question might be whether you will be
able to find a suitable replacement in the first place -- the specs suggest
that the original drive is a 40gB IDE unit and standard IDE drives are
becoming increasingly rare items and whatever you find is likely to be
leftover stock at least a couple of years old.
 
yep

a 7200 rpm drive will generally give better performance than a 5400 rpm
drive (not a dramatic improvement, but probably noticeable)


as to any possible additional heat and power consumption:

On a desktop it would be negligible
but could be a factor for a laptop

The computer in question is a handheld tablet -- probably about the same
volume as a notebook but I'm not sure what they do for cooling in one of these.

I don't know about your tablet, but mine is slow and seems to be constantly
disk bound. So moving from a 5400 rpm disk to a 7200 rmp one would give a
welcome speed increase (33% on paper, but I appreciate that there are other
factors which come into play).

Highlighting on the John's points, if your current disk is IDE then you may
find it difficult to get a replacement as most disks now are SATA. So do be
sure you get one which you can physically plug in.
