| 646873 | 2008-03-06 05:32:00 | suddenly I have this random thought wouldn't it be nice to have a program to allow you to setup a virtual disk so it can have an drive letter assigned and be be accessible from "My Compupter" and this virtual disk is made from an image file located on the harddrive okay what's written above..probably does exist, but here's the main point~ the main idea is to make it...as if running raid! so the image of the virtual drive is spread across two or more physical hdd so something like image-a on hdd1, image-b on hdd2, etc and when data is written to the virtual disk, the content can be spread out evenly across the separate image files to improve performance so basically I can setup a small virtual drive with ideally twice the performance of my physical drive so.. does a program like this exist already or is this just unpractical... |

| 646875 | 2008-03-06 06:28:00 | DAEMON tool / Alcohol product would be what we are talking here :) completely different application. Those sort of products are not designed for or capable of what is required here. Running emulated RAID would probably have a lot of overhead, and you wouldn't be able to load all your core windows files from your virtual drive. What are you thinking of using the RAID emulation to speed up? |

| 646876 | 2008-03-06 06:35:00 | You can mount a virtual HDD as a drive, but not multiple drives as RAID unless you create the RAID in Windows using those as virtual drives, read here: chitchat.at.infoseek.co.jp | The_End_Of_Reality (334) | ||
| 646877 | 2008-03-06 07:47:00 | yup I guess those utilities already exist was just interested how nobody made a program that can speed up drive access using similar principles as raid |

| 646878 | 2008-03-06 07:54:00 | I have been looking into the program link I posted and it uses a VMware disk to run the drive BUT (this is the major issue) the program does not communicate with the mount manager on the OS which means the disks that are mounted are "invisible" to the Management console, disk defrag etc in Windows, but 3rd party apps seem to see them... Now if only I can find a free software RAID program... |

| 646879 | 2008-03-06 08:48:00 | I've just tried VMware's DiskMount to mount vmware disk images but sadly it doesn't show up in management console either! so I guess now I'm looking for sofware RAID alternatives too since XP's won't work maybe I should take this idea and try it in linux might have better luck |

| 646880 | 2008-03-06 08:57:00 | Well I guess it is not supposed to be then... Can XP use a partition on a HDD and RAID that with another partition on another HDD? I have not tried that, don't have the free HDD space :p |

| 646881 | 2008-03-06 09:43:00 | Virtual Box may do some of what you want, not sure but worth a look: http://www.virtualbox.org/ |

| 646882 | 2008-03-06 09:54:00 | so basically I can setup a small virtual drive with ideally twice the performance of my physical drive Your virtual drive will still be using physical drives and RAID 0 typically doesn't deliver more than a 40% increase in raw speed which doesn't help most desktop functions after you include seek times. |
