Will attaching an external drive to my Mac Mini improve booting time?

November 20, 2007 1:36 AM

Will attaching an external Firewire drive to my G4 Mac Mini make a big difference to booting speeds and application loading times?

I'd like to use an external Firewire drive as the default boot device. I think the internal drive is a crappy 4200rpm 2.5" 60Gb drive. Booting is pretty slow. Loading applications is pretty slow. How much (if any) of a speed increase could I expect? The new drive will be faster, but will the Firewire 400 interface counteract this?

This is rather off-the-top-of-my-head, but I'm reasonably sure that FW400 is slower than both IDE and SATA connections, with a max throughput of about 50MB/s, where I think SATA starts at above 100MB/s, and IDE runs at 66MB/s (this one I'm less sure of, because of the weird things that go on when there's more than one thing per cable).

Anecdotally, it also makes sense that the external interface is slower, or it'd be being used internally too.

A nice 7200RPM external firewire drive will help considerably.

The only upgrade that is more beneficial is memory. If you don't have 1GB in that machine, I'd do that first.

Booting will be slower as the machine will always scan the firewire and USB ports to see if there is a bootable drive attached to them. There might be some setting to tell the computer to boot only from the internal hard disk. My MBP does this, but it doesn't really bother me.

I've noticed that finder is sometimes slower kicking in when an external drive is connected, but again, my machine is fast enough for it not be an annoyance. Not sure about a G4 though.

Seconding maxing out the RAM.

The Mac Mini has a really slow drive. Furthermore, the fact that it's a 2.5", not 3.5", effectively makes it slower (linear speed at the outside of a 2.5" disc turning at a given speed is lower than linear speed at the outside of a 3.5").

Here are some mini drive benchmarks. As you can see, there's no one configuration that's always fastest, but an external drive can speed things up. So can a faster internal.

If you really want to go crazy, you can connect the internal SATA jack to an external 3.5" drive, but this requires taking a Dremel to your case.

I've done exactly this.

It will be noticeably faster. The drive in the mini is ridiculously slow.

Yes. Yes, a thousand times yes!

I did it with my G4 Mini. I'm never going back!

Response by poster: Thanks for your answers. Looks like it's worth doing.

Response by poster: odinsdream: You mean you put in a 7200rpm 2.5" disc? It fit perfectly? That might also be worth doing.

I have a G4 Mini, and an external FireWire helped, even though I didn't use it for booting or applications. However, putting a 1GB RAM stick made a freakin' massive difference. It was a completely different and far better computer after the RAM upgrade.
