Multiple Partitions in OS = Problems?

[darklord110]

Looking at a friends computer, and noticed he has a c: partition which has the OS Win XP, then like D: is games, E: is music, F: is video clips, G: is pictures etc.

Does having multiple partitions on the same Hard Drive slow anything down at all compared to say just creating directories under the C:. Another friend says it does, I'm not sure. Just curious.

not in my expierence.

Not in my experience either...

Partitions have always treated me well. Good for organization, but it is best to have a system partition just in case a format may be imminent. That way all you have to reformat is that one partition while the other with personal files remains intact.

The choice of how the hard disk is partitioned can have a tangible impact on real-world performance. This is due to several different but related effects that you should keep in mind when deciding how to partition your drive:

Cluster Size: The way that the hard disk is partitioned in most cases determines the cluster size of the partition, which has a performance impact. See this section for details.

Zone Effects: Modern hard disks use zoned bit recording to allow more data to be stored on the outer tracks of the hard disk than the inner ones. This directly impacts the media transfer rate of the disk when reading one zone of the disk as opposed to another; see here for details. Hard disks fill their space starting from the outer tracks and working inward. This means that if you split a hard disk into three partitions of equal size, the first partition will have the highest transfer rate, the second will be lower, and the third lower still. Therefore, you can put the more important files on the faster partitions if transfer performance is important to you.

Seek Confinement: Seek times are roughly proportional to the linear distance across the face of the platter surfaces that the actuator must move the read/write heads. Using platters of smaller diameter improves seek time, all else being equal, and partitioning can have the same net effect. If you split a drive into multiple partitions, you restrict the read/write heads to a subsection of the physical disk when seeking, as long as you stay within the same partition. The tradeoff is that if you do a lot of moving data between partitions, or accessing multiple partitions simultaneously, you'll force the heads to "jump" back and forth between two completely different areas of the disk, reducing performance. Some who truly desire performance over all else will buy a hard disk with double the capacity that they need, partition it in two pieces and use only the first half! Or use the second half only for archiving infrequently-used data.

Defragmentation Time: Larger partitions tend to become full of, well, more data, obviously. :^) A larger partition can take much longer to defragment than a smaller one. Since fragmentation reduces performance, some people prefer to partition their drives to reduce defragmentation time, enabling them to do it more frequently.


Have fun

That is what I do also, make a partition just for my OS. That is so like you said it is easy to do a reinstall should the need arise. I also make partitions for my different catagories; like music, games, and so on. I also have the benifit of having a second drive for a partition for backup and for an image I make of my OS install partition for a quick get up and go after XP has knocked me down.

Hey, not far from the Cities myself. Though I am a transplant of 3 years, I have to be honest and say I can't stand it any longer. Nice place, its just not for me. Heading back out west ASAIC. Thinking Washington or Oregon(like the coast, but hate California).

I'm going on about 7 months now of living here.

I was from Florida...I was tired of the year round 90 degree temperatures and the awful humidity.
