When compared to cd-rom, virtual drive offers numerous advantages not found in the latter, including the ability to function even in the absence of a disc, the capacity to process multiple discs simultaneously even in the absence of a cd-rom, quicker processing speeds, and portability. The virtual drive may operate directly on the hard drive at a speed of up to 200 times the normal speed, respond fast, and play video files smoothly and continuously without interrupting. The average transfer rate of a hard drive may reach up to 10-15 megabytes per second, whereas the transfer rate of a virtual drive can reach up to 150 kb per second. This means that the virtual drive’s transfer rate is about 100 times quicker than that of a hard drive. In modern computers, the majority of motherboards use an ultra-dma hard disk controller, which can achieve transfer speeds of up to 33 megabits per second (220x). I have outlined each of the typical capabilities of virtual drive in the following paragraphs. The virtual drive is the ideal partner for portable electronic devices such as laptops. the ideally suited partner for the notebook: It is possible to copy cd image files from other computers or the network using a virtual drive, which may help alleviate many of the typical issues that plague laptops, such as a lack of a CD-ROM drive, excessively poor performance, inconvenient portability, and high energy consumption. The virtual drive is able to make a duplicate of a disc. This copy would result in the production of a virtual cd file matching to the replicated cd by the virtual drive, which makes it simple to handle this file. It does not transfer hundreds of thousands of files from the disk to the hard drive since doing so would cause these files to malfunction due to the fact that many disks need the usage of a cd-rom in order to operate. Now thanks to the virtual drive, all of these issues are resolved entirely. It is possible to play many discs on the virtual drive at the same time. The virtual drive is capable of running numerous software programs on disks at the same time. For instance, we may read the Encyclopedia Britannica on one virtual drive, install Kingsoft 2000 on another virtual drive, and listen to the CD album using a real cd-rom all at the same time. Because of the vast number of requirements, a single CD-ROM was unable to fulfill all of them. compression: compression is a technique that is frequently used by virtual drives. virtual drives generally utilize unique compression and decompression methods. The compression ratio achieves values of up to or more than fifty percent. It would decompress files automatically without affecting the playing quality of videos in any way. The characteristics of a CD tower are included in the virtual drive as well. The costly CD tower may be totally replaced by the less expensive virtual drive, which can store an infinite number of disks directly. It provides a great deal of convenience, such as the elimination of the need to swap disks, a fast operating speed, a significant amount of space saved on hard drives, and the absence of any requirement to maintain hardware. Installing video games or other huge software is possible with the virtual drive. You may be able to install games on your computer with the assistance of the virtual drive. When games are downloaded from the internet as image files, a virtual drive is almost always required in order to read these image files and install games. This creates an excellent platform for a big number of gamers to play on at the same time. The operating system may be installed in a risk-free manner by using the virtual drive. The best option for installing Windows XP or any other operating system is to use the green virtual disk found in the preinstallation environment (PE). The ISO image file must first be loaded into your hard drive, and after that is done, you must click on the virtual drive in order to begin running the setup files. Naturally, if the file is a gho, you might use the ghost browser in PE to install the operating system if it is the case that it is! The installation of the operating system may now be completed without the usage of a CD-ROM drive.
