Hitachi 7200 drive temperatures

[laban]

How much hotter does the 7200 60Gig TravelStar run than a standard slow 4200 notebook drive?

I've done some searching & googling, and haven't found much, so I thought I would try and get some information from people that have used both.

Not much. There are too many 4200RPM drives, so why don't you list one and I'll tell you exactly how much the power difference is.

The one I'm replacing is a Fujitsu MHT2030AT. Just a 30Gig 2mb 4200rpm notebook HDD

I just replaced the 4200rpm drive in my averatec 3150 with on eof the 60gig Travelstars from Newegg, and have noticed almost no increase in heat.
It is fast too, load times have improved greatly.

-------------
The 60GB Hitachi drives uses very little more power than a low power 4200RPM drive. Not enough to make you even worry about heat.

For example, say you use a laptop with a 60WHr battery and wanted to know how much more power the 7200RPM drive used under a reasonably realistic load: idle 50 minutes, seeking 0.5 minutes and reading/writing 9.5 minutes per hour.

Fujitsu: (50 min * 0.65W + 0.5 min * 2.3W + 9.5 min * 2.1W) * 1 Hr/60 min = 0.89WHr rate
Hitachi: (50 min * 0.85W + 0.5 min * 2.6W + 9.5 min * 2.5W) * 1 Hr/60 min = 1.13WHr rate

I doubt you'd be able to feel that difference (0.24W average). And it doesn't even make a 0.5% difference to battery life (actually = 0.4% difference) with the example 60WHr battery. And more realistically anyways the 7200RPM drive with a much larger cache would be in seek or read/write modes much less often than a 4200RPM drive, so a real-life power difference would be a little smaller.

a 2.5" HD has a max heat output of 2.5w
(500ma at 5v)
most run at about 1w idle and 1.5-2.25 while seeking
there are almost no applications where swaping to a 7.2k from a 4.2k will make a difference (in a laptop anyways)

I hope you're not serious. The transfer rate on a 7200RPM drive (disk<->buffer/interface) is 50% higher than the 4200RPM drive listed above. I've had both and I can guarantee you that everything from loading programs and games to booting and going into and out of hibernation is much, much faster on the 7200RPM drive than the stock 4200RPM drive.

sorry should have been clearer
i ment applications in reference to the amount of heat a given drive would produce

i agree whole hartedly that it will be much faster
