Virtual machine applications such as Parallels, Virtual Pc and VM Ware are becoming increasingly popular as they allow users a number of options that would otherwise be unavailable to them for example a clean system for faster performance or perhaps the ability to test an application in isolation from your main operating system. Sadly the common hard drive is still a factor that needs consideration as fragmentation can cause data problems.
Virtual machines must still make use of the slowest part of any modern computer system: hard drive technology. Hard Drives can be partitioned to appear as dedicated individual devices, these devices are then often utilized to store virtual partitions and virtual operating systems. Underneath this "virtual" layer, the hardware is storing data as it always has, in a fragmented inefficient manner.
Hard disk fragmentation occurs when files are split in to multiple chunks as they are slotted into spare space on the hard drive. If you are running a solitary OS chances are you have already noticed considerable slow down in your system since purchase. Just imagine two or more OS's running causing the same file fragmentation! Pretty soon your system could come to a grinding halt.
What is more, the premature wear that all of this fragmentation can cause to the hard disk storage can dramatically reduce the useable life of the storage below. Even complex, high performance, RAID arrays can be reduced to a snail like crawl due to high levels of fragmentation. If this problem starts to show itself on a number of the storage devices in any array you could be left with a situation where data recovery is your only option.
You would like to think that as the problem of file fragmentation has been with us since the advent of hard drive based computer systems, operating system vendors would have come up with a software solution to ensure the problem is eradicated at source. Whilst Mac OS X will partially help with files under a 20 mb size, Windows operating systems seem to pay it no heed whatsoever.
Utilizing defragmentation tools can help to alleviate the problem but often the use of some of these tools is very invasive and will render your system virtually unusable while they are running so what other options do you have.
Fortunately we are not left to the operating systems alone as there are a number of third party defragmentation applications that are far superior to the inbuilt OS tools. These can be scheduled to run when system usage is very low for example whilst the system is idle or the screen saver is running. As you go defragmentation is my personal choice.
Use dedicated hardware for the Virtual Machines: Whilst it may appear to be a contradiction in terms, running the virtual machine from a dedicated hard disk or RAID Array is probably the most efficient method of running the machine at all. It leads to the minimum of wear on the individual hard disk devices and means that running even simultaneous defragmentation is possible. - 16732
