USB flash disk Mass Production

Section 1 What is mass production

Mass production is the mass production of a batch of products in the factory. For example, a USB flash drive needs to be formatted in batches before being released. For example, a full batch of USB flash drives are set to USB-ZIP one by one. We ordinary users use the manufacturers of mass production software, U disk can be set to another combination, for example, U disk simulation of a USB-CDROM and a USB-ZIP plus a combination of a USB-HDD.
The main purpose of our mass production is to get this USB-CDROM because its startup compatibility is strongest. The extra ZIP and HDD are gifts.

Section 2 background of mass production

1. Common scenarios. There will always be many friends around who need to reinstall the system. You cannot always carry a 5-inch system CD or a 3-inch mobile hard disk with you, however, it is very likely that you often carry a finger-sized USB flash drive (hanging in a lock ring or in your wallet) with you. The feeling of a disk moving all over the world is quite cool.
2. extreme cases. Almost all thin and thin laptops do not have optical drives, and they are likely to only support USB-CDROM boot, does not support USB-HDD boot, does not support Nic boot computer, if they want to reinstall the system, at this time, the mass production of the U disk will be used, and in some cases (remove the laptop hard disk will lose the warranty) is almost the only re-installation means.

Of course, if your friends around the computer all support USB-HDD boot, you do not need to mass production of your U disk, with old peach or deep U disk assistant, make your U disk into a USB-HDD boot disk on the line.

Section 3 selection of production master

I spent a few months on several authoritative mass production forums, including worry-free start-up, Digital Home, and deep USB flash drive. To sum up, the most widely used main control chips are group-connected Phison and Optimus Skymedi. They are used for different reasons.

The Group-connected Phison master chip is the most used, because it has the best compatibility, the highest production success rate (99%), and the fastest read/write speed (horrible write 16 read 31 ), therefore, it is a specialized product for cainiao mass production.

Qingtai Skymedi master chip also has a large number of users, but its mass production is easy to fail, and its compatibility and read/write speed are also average. However, it has an advantage that none of the other masters has it, optimus Skymedi master supports the true sense of the "Three Qi", that is, the support for USB-CD/USB-ZIP/USB-HDD three disk coexistence and three disk boot! Skymedi is different from longke's fake trigger! This is a huge appetite for DIY geeks, so it is a professional product for mass production.

Phison has a disadvantage, is that it does not support the amount of output USB-CD and USB-HDD coexist at the same time, which makes people very depressed, especially the author of the two new notebook does not support USB-ZIP start, if it is not possible to enable the dual startup, you have to wait for Phison to upgrade the production tool. As a result, Skymedi enjoys a very low price at this point. In the case of sanqi, how many DIY geeks (including the author) drool.
But the new notebook are slowly eliminating ZIP boot, only support USB-CD and USB-HDD boot, so in the eyes of general users three open temptation is not very big.

The Skymedi master has two mainstream versions, one being and the other being 281. The former ipv211 supports dual-chip memory, while the latter ipv281 only supports single-chip memory. In a desktop computer, dual-channel memory is hard to make people feel faster, but the speed of dual-channel memory on a USB flash drive can be more than half faster than that of a single channel! Therefore, if you can choose one, you 'd better choose a USB flash drive with the master.

The Phison master also has several mainstream versions, including UP10, UP11, and UP12. Through the practices of the masses in several authoritative forums, we found that UP10 has the best compatibility, it can start a vast majority of new and old computers. However, most popular versions on the market are UP11 because of its fast read/write speed. Now UP10 is hard to find.

The Skymedi Master always prefers to use some strange memory, which is why Manufacturers (including regular and shanzhai) like it, but this is also the main reason for its high production failure rate, GOOGLE or is a repair tool.
Phison is doing a lot better in this regard. It is very memory-dropping, but as long as the memory is right, Phison's mass production will be almost all success without surprise and danger, making it boring.

Section 4 selection of USB flash drives
At present, the USB flash drive that uses Phison is dominated by the Yuzhan AH320 WeChat flash drive. The largest number of users is 8 GB (because the most cost-effective). You can choose which USB flash drive to start the forum, all of them are successful h320 8g production posts.
The USB flash drive with/master is mainly a golden ten-ton 4G Yi disk (which is also cost-effective). The volume of goods distributed in the computer cities in various regions can be said to be sea-jumping, and other brands (including Yuzhan) all are on the edge. Therefore, it is highly likely to encounter Kingston fake goods. Use ChipGenius software to check whether the master is a chip that has never been seen before.

Section 5 selecting ISO is more important
Many people often complain in the forum that I have been successful in mass production. Why can't I start my computer? This problem is complicated. First, the computer must support USB boot, and then the ISO you selected during mass production must support USB boot.
A lot of people ignore this: USB Drive boot and IDE Drive boot are different. This has caused a lot of people to be confused: it is normal for me to test ISO startup on a virtual machine. Why can't I start it after I create a USB flash disk. That's because in virtual machines, people are used to putting ISO into the IDE optical drive for testing, so they didn't consider loading some USB drivers under DOS.
For example, the old computer can access files on the USB flash drive after UBSASPI. SYS is loaded, but the new computer may have a deadlock when USBASPI. SYS is loaded. Therefore, refer to the production-specific ISO made by experts. It is very helpful for you to DIY an ISO you like.
I suggest that you go to the above-mentioned authoritative U disk boot forum to download some ISO specially made for mass production, which have been tested by countless users, compatibility is guaranteed.
