Yes I have been wondering about this myself for quite some years.

Re: i was wondering
There is no real answer. The throughput of a harddisk is not only depending on its rotation speed but also on other things.

Re: i was wondering
Yes give us an exensive list of the number of files and their sizes and folder layout so we can calculate for a few hours

Re: i was wondering
as SI said, the rotation speed is not the only thing which determines how fast data can go onto it
Things like the IDE interface - is it on the same cable as the other drive?
What DMA mode are both drives on
what else is using the drive(s) at the same time?
etc etc etc
the only real way to find out is to try as any answer is likely to be a guess

Re: i was wondering
I vote 20 minutes. Or an hour or something. In fact, make it a sweepstake.
Edit:
On a quick test I can shift about a gig a minute across my two drives, so I'm going back to my 20 minute guess.

I am taking bets for the time length. All those who are subjected to losses must hang their head in shame and subject themselves to MacDonalds for 2 weeks.

Re: i was wondering
Maybe you should wait a little with actually doing it. The onramp of this is just mildly erotic.

Re: i was wondering
You will need to know the total throughput of the PC to be able to calculate this with any accuracy.

Re: i was wondering
Hm, I estimate a HDD speed bewteen 15MB/s and 30MB/s. Ie. let's say 30min worst case, 14min best case.
Unfortunately I'd guess a slower speed, so say something like 25min.

15-30 MB/seconds could be about right for a 7200rpm disk.
When I was doing my internship at Océ they tested the throughput of a harddisk for a printer (normal OEM HD). The numbers did indeed vary between 15 and 30 MB/second but heavilly depended on the cluster-size of the filesystem and the size of the files that were transfered.
Thereby they were testing it on a UNIX machine.
How long have you been at it Theams?
