I still haven't found a solid answer to the drive speed question. I've seen reports of 4200 RPM but also a report that the Mini uses a Seagate Momentus mechanism which (according to Seagate) is a 5400 RPM drive. Apple System Profiler should (I think) be definitive ?


Sorry, to give you the bad news but the drive is 4200 RPM. I got the Mac Mini with the 80GB disk. The Apple System Profiler says the disk is a Toshiba MK8025GAS drive. I searched the web and found it's a 4200RPM drive with an 8MB buffer.

Thanks for the clarification - next question of course is how much difference does this make :-)

I have found that our application runs very nicely on the Mac Mini. However, we are not disk intensive. I haven't done any timing tests regarding speed of the disk. The speed of the disk would most likely show up in applications like iMovie. Because of a software deadline I haven't had a chance to move any digital video over to try that out.

My first impressions are that the Mac Mini is a nice little machine. Very quiet, does a good job of running the types of apps that a Mac Mini customer would run, and is so small it will fit anywhere.


One thing that I have noticed is the version of Darwin is different on the Mac Mini. All of my computers are Darwin version are 7.7.0 and the Mac mini is version 7.7.1 The GCC version is the same everywhere.

I believe the different Darwin versions will prevent the distributed build mechanism from 'seeing' this machine. Earlier XCode builds had a flaw where they would attempt to distribute to mismatched machines (notably compiler versions) which would cause all sorts of weird and wonderful errors. The fix appeared to be to check and compare the strings reported and only distribute to identical matches.

Is the Mac OS X version on the mini an identical 10.3.7 7S215 ? Or is it subtly different ? Until some subsequent update brings everything back into line it seems unlikely that the version mismatch will be resolved and we'll be able to distribute builds to the Mac Mini.

The Mac OS X version on mini is 10.3.7 7T21. Rich from Bare Bones also clarified that the OS version has to be identical. Sounds like I have to just wait until it all gets matched up again.
