All well and good but highly speculative. I need to know can I put any of the 80Gb 7200rpm 2.5" drives currently available into the mini.....
Does anybody have any factual information which would support the use of faster drives in z miniMac...
The problem is that no one can have any factual info except Apple. You want good hard info, you have to talk to them. No one even knows what sort of drive they use (brand and model).
I did some checking here if you want fact and figures.
Here are the power specs on a random Fujitsu 40GB 4200 HD
http://www.fujitsu.com/global/services/computing/storage/hdd/mhdd/mht20ahxx-catalog.html
Spin up 5.0W maximum
Read / Write 2.3W typical
Idle 0.85W typical
Standby 0.25W typical
Sleep 0.10W typical
Here they are for a Hitachi 60GB 7200 RPM HD (I am aware of no one who makes 80GB 7200 RPM drives):
http://www.hitachigst.com/hdd/support/7k60/7k60.htm
Startup (max. peak) 5.5 W
Seek (average) 2.6 W
Read (average) 2.5 W
Write (average) 2.5 W
Performance idle (average) 2.0 W
Active idle (average) 1.3 W
Low power idle (average) 0.85 W
Standby (average) 0.25 W
Sleep 0.1 W
You can see that the 7200 uses the same power at sleep/standby/idle as the 4200 and in general, it uses about 10% more during use. Well, if you figure the 7200 RPM does things in 40% faster times than the 4200 RPM, that extra power during reads is a moot point (and in fact the 7200 could actually run cooler based on those numbers). When the HD is just sitting there, they both act exactly the same. If you're using it for normal usage, I don't think it would have any affect. If you go and run something that is going to use your HD continuously for long periods of time, then it might have an affect (like running some programs while you are away that continuously thrash at the HD).
Is this speculative? Yes, of course. Am I a HD expert? No. Might I have missed a critical factor? Yes. Is there any hard info you can get? My best bet would be to call up Apple. I'm willing to guess that 9/10 people you talk to will tell you that Apple will void your warranty if you don't use their HD or some other party line. Anyone else out there know? How could they, the Mini is a week from shipping as it is.
If you do a search of 7200 rpm and PowerBook, you'll probably find some useful info. Trying to put the 7200 RPM in a PB is pretty similar.
