Many times we will encounter such scenes and we will soon leave home. However, we find that there are important data on the computer that are not copied to the USB flash drive that you carry with you. It's really easy to see the “slow forward†copy progress bar. Hey, sometimes it can instantly crash.
If you can increase the USB transfer speed, you can undoubtedly save more waiting time. Under normal circumstances, many users will choose to replace a new laptop or desktop with a USB 3.0 interface, but they cannot do anything about the old devices. Perhaps it is time to use such a small accessory.
This is a 7-port USB3.0 PCI-E expansion card that ORICCO has recently introduced. It can be said to be a new companion to the old desktop. Its exterior packaging was made of black hard paper material, with ORICO lettering on the front and extension cards, and a functional description in English on the back.
The expansion card is packaged with a thicker anti-static bag. A yellow label with the English warning “Warning†is attached to the sealing position. After opening the sealing label, this 7-port expansion card can be removed.
Usually on the back of the host with four USB2.0 interface, in front of two USB2.0 interface, but this ORICO expansion card and ordinary computer's own USB interface is different, it directly expands 7 USB3.0 The interface can achieve efficient transmission at the same time, improve our work efficiency, and allow faster data transmission.
The PVU3-7U uses a solid-state capacitor, which can effectively ensure the voltage filtering effect. The overall design of the blue PCB motherboard is matched with a black block. Not only equipped with a high-performance master chip (VI813's VL813/VL805), but also from the lower right corner of the figure can see a 15pin sata power supply interface, making this expansion card can not only achieve rapid data transfer, but also improve stability Sex and service life.
The use of the expansion card does not need to be too professional. In fact, it proves that as long as you can open the cover, you can install it in a small white style. From the figure below, you can see that there is a two-segment split plug-in strip at the bottom of the expansion card, which can be inserted into the PCI-E slot on the mainboard of the host computer. If you don't know what a PCI-E slot is, just find a suitable slot on the motherboard. The installation process only takes two steps. After inserting it into the slot, turn on the 15-pin power connector.
It should be said that almost all motherboards have such grooves, so this expansion card can also be applied to more computer hosts (PCI-E 1X, PCI-E 2X, PCI-E 4X are applicable, PCI-E 8X, PCI-E 16X). The 7 USB3.0 interfaces are used independently of each other, and they can also support hot-swap functionality. In simple terms, you can use the U-disk with the plug-in. Unplug it when not in use.
From the front, it is seven USB 3.0 interface expansion stations that can be inserted into multiple U disks. However, it should be noted that although it can be applied to most mainboards, it is not applicable to the structure of some chassis. , That is, some of the chassis back of the back of the bottom of the bar is narrow, although the expansion card can be installed up, because the chassis of the bar is narrow, from the outside can not be inserted into the U disk, it must be on the chassis of the bar Slightly improved.
Installation As shown in the figure below, in actual use, the computer's motherboard will automatically identify the driver that needs to be installed.
The actual rendering after installation is complete.
If you cannot achieve automatic installation, you can manually install the driver through the CD that comes with the expansion card. This expansion card also does not come with a certificate, manual and warranty card, the only incomprehensible is to use English.
Driver installation.
The actual data test. In the actual test, because of the comprehensive environment of the test environment and the configuration of the computer, the data obtained does not mean that each user will have the same effect.
In general, when the PVU3-7U expansion card is used in actual use, the expansion of the 7 ports is relatively far enough to meet the user's need for expansion, especially in terms of the transmission speed of USB 2.0. Better results save the user's actual waiting time, and all of this is even more powerful for older computers. The only downside is that the width of the barrier opening of different user chassis is inconsistent, resulting in individual desktops. Unusable unless some width modification is done properly.
Epoxy fiberglass winding tube is made of fiberglass yarn impregnated with epoxy resin etc, and then rolled in wet method, and then dried and consolidated. Its heat resistance level can be up to H level, and it also has excellent electrical and mechanical properties, low dielectrical loss, no deformation, chemical resistant etc. It can be used as main insulator on H grade dry type transformers, load tap changer, reactor, lightning protector, SF6 Inductor etc.
Fiberglass epoxy coated pipe has good dielectric properties and machinability. Applicable to electrical equipment as insulation components, dry-type transformer coil insulation tube and transformer insulation ring.
