USB Disk Maintenance Of Life

USB disk rewritable times is the normal life span, generally U-disk MLC particles rewritable more than 10,000 times, while the use of SLC particles U disk life is up to 10 million times.Never in the U disk light flashes when the pull out the flash drive too fast, because then U disk is reading or writing data, half-way pull may cause hardware, data corruption. Do not turn off immediately after the backup documents related to the program, because at that time on the U disk light still flashing, indicating that the program is not completely over, then pull out the U disk, easily affect the backup. So files to flash drive, it should be some time to close the relevant procedures to prevent accidents

Solution for USB3.0 device performance slow speed problem

In the test USB3.0 mobile hard disk, found a strange phenomenon: If the USB3.0 device slowly inserted or sub-inserted into the USB3.0 port (the so-called insert into a small part of the insert, do a little stay and then complete insert )

     With HDD Tach detection USB3.0 mobile hard drive burst transmission speed, is actually the speed of USB2.0 (35MB / s or so), in the use of NEC, ASMedia USB3.0
Chip on the motherboard after the verification, have this phenomenon, which is why?

      Later, by carefully studying the USB2.0, USB3.0 wiring definition and many tests, and finally the truth, let us take a look at the reasons
1.USB2.0, USB3.0 appearance (Figure 1)

The difference between SLC, MLC and TLC

The difference between SLC, MLC and TLCThe TLC chip technology of the X3 (3-bit-per-cell) architecture is an extension of the MLC and TLC technologies. The earliest NAND Flash technology architecture is SLC (Single-Level Cell), and the principle is in one memory storage unit (cell). The data of one bit is stored until the MLC (Multi-Level Cell) technology is connected, and the architecture evolves into one memory storage unit to store two bits.
In 2009, the TLC architecture was officially launched, representing a memory storage unit that can store 3 bits, and the cost is further reduced.

Will TPEC-C interface be the future?

First, the difference between the three types of type-A B C is Type-A (Standard-A), Type-B (Micro-B), and Type-C. Standard Type-A is the most widely used interface standard for computers and electronic accessories, the mouse, U disk, the big one on the data line is the interface, the volume is also the largest; Type-B standard is the main application of 3.5-inch mobile hard disk, printer , Monitors and other equipment, the volume is smaller than the Type-A. And in order to move the convenience of electronic devices, but also the birth of the application of digital cameras on the Mini USB and widely used in smart phones on the Micro USB standard.
