SLC = single-stage Cell, i.e. 1bit/cell, which has high speed, long service life, extremely expensive price (about three times the price of MLC3) and service life of about 65438+ million times.

MLC=Multi-LevelCell, that is, 2bit/cell, average speed and average life, average price, about 3000- 10000 erasure life.

TLC = triary-level cell, which is 3bit/cell. There is also a Flash manufacturer named 8LC, which is slow, short-lived, cheap and has a life span of about 500 times. At present, no manufacturer can achieve 1000 times.

There is no difference in performance parameters alone, but the life of TLC is still very worrying, but at present, most TLC disks provide a four-year or even five-year warranty, which is no longer a problem. After all, computers update quickly. If the price is similar, you can choose MLC. If the price difference is too big, then TLC.

System disk? System disk refers to a kind of computer software. It refers to a system that controls and coordinates computers and external devices, supports the development and operation of application software, and is a collection of various programs without user intervention. An indispensable tool for reinstalling the computer operating system. The second refers to the hard disk partition with operating system.

strong function

Arrange, monitor and maintain computer systems;

Responsible for the management of various independent hardware in the computer system, so that they can coordinate their work.

System software enables computer users and other software to regard the computer as a whole, regardless of how each underlying hardware works.

Fold to solve the problem

In fact, manual packaging only needs to solve two problems, and existing tools only solve these two problems. These two problems are power supply judgment, that is, breaking the HAL limit (which is necessary because the configuration of the mother machine and the client is usually different) and SRS driver (which is necessary because the current machine configuration is updated faster and faster). Which can improve that usability of the recovery disk). The advantage of the tool is that it doesn't need manual operation (the programs are all written by yourself) and it is convenient to expand (for example, you can add any programs suitable for running or hide the black box of P processing). The following is how to break through these two aspects and reach the manual packaging system.

Most users use CD-ROM to install the system. First, set the BIOS first boot to CD boot. The operation is as follows.

1. Set the BIOS to the CD-ROM drive, and then put it in the CD-ROM drive, and the CD-ROM drive will guide it into the CD-ROM drive interface.

2. First, partition the hard disk. Enter the PQ interface, and you will see the size and properties of your hard disk. Select "Job" and "Create", and choose to create as the "primary partition", that is, the "primary partition" for installing the system in the future. Next, choose the partition type, because it is a GHOST system, so any FAT NTFS will do. The following is to select the size of the primary partition. It is suggested to set the size between 10- 15G, that is, between 10000M- 15000M.

3. So a new partition was established. Next, select unallocated space (black and white position unallocated). Still select Job and Create, this time select Logical Partition Sector. You can assign the partition type and size according to your personal needs. The required hard disk partition has been allocated.

4. The key step is to set the "C disk", that is, the "main magnetic field" as the role. Click "Operation", "Advanced" and "Set as Function", and you will be prompted whether to set this partition as a function, and then select "OK".

When the operation is finished, click Execute. When finished, you will be prompted to restart. All right, the partition step is complete. The next step is automatic installation, and the next step is very simple.
