Two points to limit the speed of U disk

In the process of using U disk, sometimes you will encounter a U disk read and write speed is very slow situation, at this time most users will think that the main chip is a U disk problem caused by, in fact, is not exactly like this, U disk is composed of the main control chip and Flash chip, Normal situation u disk speed mainly depends on the main control chip and Flash chip in these two aspects.

In the chip aspect, the main has SLC, MLC, TLC three kinds, SLC chip USB flash drive has the obvious superiority in the speed, fully shows the SLC chip the formidable performance. SLC chip has a strong advantage in loading speed and data transmission speed, and SLC is lower than MLC in energy consumption. In addition, the SLC chip can guarantee 100,000 times of stable access, so it has a longer service life. However, because SLC price is more expensive, more quality products to choose MLC chip. The reason is that the MLC architecture can store more than 4 values at a time, so the MLC architecture has a high storage density, and can use the old production Cheng to increase the capacity of the product, without additional investment in production equipment, cost and yield advantages. Compared with SLC, MLC production cost is lower and capacity is large.

In addition, the current market on the use of U disk main control, there are several: Chi-Tai, group, Hui Rong, Lian Sheng, Xin Chuang, and the core State control. Each of the main controls used in different brand USB flash drive, its characteristics are not the same, which is why different brand products have differences. The main control is different, but did not make the advantages of USB3.0 full play out, we look forward to the main control of USB flash drive optimization and development, so that USB3.0 play a real fast role.

U disk read and write speed further affect our efficiency, to make U disk read and write faster, first of all to understand the blocking U disk speed of the two points, in the purchase of U disk when you can choose to a good quality, the main control chip and flash chip two elements are mentioned up, The speed of the U disk is not a problem.
