u disk loading system benefits

U disk loading system is now more and more popular, mainly the benefits, but many people do not know what the benefits? Today's example analysis: disk installed XP ( With EWF), there is currently a mobile hard disk with XP and an XP USB flash drive, so I think my opinion should have some reference value for you.

A lot of benefits

1. Portable, obviously, this is the biggest advantage

2. Large capacity, compared to the maintenance CD, you can integrate N maintenance tools, and even put down several ghost images

3. Maintenance is powerful, because of the large capacity, you can put more tools. You can also set up multiple boot, such as USB-CDROM+USB-ZIP+USB-HDD, of course, it is relatively difficult to create such a disk

4. The security is high. For entertainment purposes, the system on the mobile hard disk/U disk is completely independent of the system of the local hard disk. As long as the local hard disk is shielded, no problem will occur to the local system regardless of any problems in the mobile system. Compared with the local hard disk dual system, it is also safer.

5. Ease of use, as long as the motherboard supports USB boot

Disadvantages are also

1. The hardware requirements are more critical, especially the U disk

2. Compatibility is not perfect enough. This is because there is no uniform standard for USB booting, and different system compatibility is different. Basically, the order from good to bad is DOS>PE>XPE>XP

3. The running speed is not as good as the local hard disk, but many children's shoes have a misunderstanding. The USB read/write speed is far less than the local hard disk. In fact, the theoretical reading speed of USB2.0 is 60MB/s, which is enough for mainstream applications. For the system to run, in addition to reading and writing large files, other aspects do not feel any effect. Take my mobile hard disk as an example, the measured read speed is 30MB/s, and the local hard drive is 54MB/s. The time when my mobile hard disk is newly installed XP is about 40~50 seconds from the start to the desktop. Because the U disk has EWF, the startup time is about 20 seconds, otherwise it takes about 2 minutes.

4. Installation is inconvenient, basically the installation difficulty is DOS>PE>XPE>XP is the most difficult

5. The function is more lossy than the local system.

Of course, no matter what kind of method, the benefits are natural and have shortcomings. These must be measured by everyone. In short, what kind of installation system method should be chosen according to your actual situation. The situation to choose.
