Hard Drive for Mini


Recommended Posts

AFAIK, the Mini just uses a standard laptop hard drive - and the number you're probably thinking of is 7200 RPM. That shouldn't be too hard to find, once you're looking for the right RPM speed ;). The only one I found on Newegg is this 40 GB Hitachi, though.

One thing you need to remember is that a laptop hard drive has a much smaller area than an equivalent desktop hard drive, therefore the information density is higher. Because of this, a 5400 RPM notebook drive is going to be faster than an equal sized 5400 RPM desktop drive. I upgraded my iBook from a 4200 RPM 10GB drive to a 5400 RPM 40GB drive, and there was a huge difference in performance. The mini, as far as I've heard, usually comes with a 4200 RPM drive. You might want to look for a 5400 instead of 7200 RPM drive for it, as it will save you a bunch of money, and you are likely to find a little larger drives in that speed.

my mini has 5400rpm, and i recently have just bought an external firewire hd case and put a 7200 maxtor on it. now the mini boots up off the firewire hd, but i think there is no performance difference in using it. is it because of the limited bandiwth of the firewire?

Not really. Go back and read what I wrote before about the physical size of the drive making a difference. A 5400 RPM 2.5" drive is going to have higher performance than a 5400 RPM 3.5" drive of a similar size since the information stored on it is more dense. Not quite as high as a 7200 RPM 3.5" drive, but so close that you probably wouldn't tell the difference in most cases. The spindle speed isn't the only factor in drive speed, either. The buffer size and seek times are important too. It may be that your internal drive has an 8MB buffer and your external one only has 2MB.

    • Close, but it is for any application starting, not just during boot time. In fact, it probably will not improve boot time at all because during a boot, the CPU is already boosting, so a pre-boost wouldn't change anything. I agree that it isn't exciting (especially considering every other OS already does it), but it is a good thing, even if they are just playing catch up.
    • Any so called performance increase will be in milliseconds, which nobody will actually notice in real world usage.
    • All it does is use the CPU more efficiently during boot to speed up boot times. That's it. Yawn....
    • It's not a one or the other kind of thing. Software should run efficiently, and the operating system should appropriately manage the CPU clocks. You could have the best most optimized software on earth, and it will still run faster if the CPU does a better job of boosting as needed. All this is doing is pre-boosting the CPU based on user actions, instead of waiting for the normal detection mechanism to kick in. If the OS knows it is about to need more CPU, why shouldn't it use that knowledge? It's the same idea of downshifting before passing someone, instead of just burying your foot into the peddle and waiting for the transmission to figure out what you want to do.
