Figure me this, a computer logic problem that defies logic

K, someone tell me how/why this is possible in today's computing world.

I can burn an FULL 4.7GB DVD-RW in 10mins, but when i go to copy all those files back to my hard disk, it takes the computer 20ish minutes to copy back :/

I can download 67.2MB of files from www.microsoft.com in 45 seconds, yet when i go to install the software that it is, it takes 5-10 mins to install...

Now i'm not by any means a hardware genius when it comes to all those detailed read/write speed numbers, but with a WD 120GB 7200rpm 8MB buffer drive... shouldn't things move a little more briskly then that when it comes to internal stuff like moving files and what not... I'm even on a brand new install of windows (hence the copying of huge amounts of data from backup dvds) and this performance is just annoying.

P.S. I hear longhorn goes a long way to fix some of these problems with it's behind the scenes use of SQL... not sure how true that is, but damn will it be a relief if so.

Sorry for the rant, but had to post something when i saw irony of this magnitude.
 
For the downloading of files, then installing. It may take longer to install because the you downloaded the files while they were compressed. When you install them, they are decompressing, and installing at the same time.

yeah, i realize that and that's why it's kind of tolerable, but i'd still think we would have improved computer performance beyond this pace by now... i just think it's ridiculous how portable files are externally, yet internal transfer speeds and such are so damn slow still...
 
A lot of the MS stuff is downloaded as you install it. The initial download is just the setup program, then as you configure it, it downloads as it installs.

Same as the IE6 patch for WinME.
 
your haard drive must not be fast enough, get scsi and a new fast dvd reading drive
 
i would go scsi if i could justify those prices :(... my next rig (sometime this december) is either going to be scsi or SATA v2. hopefully that will pep thigs up a bit... but that's still 10 months off :|
 
Also remember that it's got to temporary store a lot of those files somewhere so it will most likely be using the hard drive for that. So while you are uncompressing a file it has to read a part of the file off the HD, uncompress it, then write the uncompressed chunk back to another spot on the HD. Since most HDs can't read/write at the same time this creates a bit of a problem as it has to jump back and forth from one spot to another on the drive.

That and read speeds are much higher than write speeds on HDs. For a DVD burner it could be quite possible that it can write faster than a HD could although I'd have to look at some numbers to be sure of this.

DVD burners cannot not write nearly as fast as hard drives.
 
as long as we have hard drives with spinning disks they will be the bottle neck of the system.

I can't wait for some solid state drives to become slightly more mainstream.
 
Installing stuff usually isn't just a matter of copying over files, especially with stuff like windows updates. It has to update the registry and other config files so that windows knows that those updated files are there. Also, it downloads fast because it is one large file, but then when it uncompresses it has to deal with hundreds of files, so that just takes longer.
 
And don't forget how it has to edit a shitload of other files, too...like dll's and vxd's.
