Lenovo ThinkPad X230 notebook has only three USB ports, one of which is USB2.0, two USB3.0 For everyday use, a wireless mouse requires one, a keyboard requires one, a mobile hard disk requires one, and then the notebook has no USB interface, this time if you need to insert a U disk, if you need to insert a data cable, there is no way Baidu for a moment, found X230 has an Express Card slot, you can use this slot to transfer USB3.0, Ma Yun found that there are several models, some out of 2 USB ports, and some out of 3 USB ports Another is the difference between the adapter chip, some NEC chip, although not heard, but it is understood that relatively new, stable use of small heat; some ASM chip, ASM chip heard, many high-end mobile hard drives are using ASM chip , Output speed, support functions, and even support the Trim function, my mobile hard disk is the use of ASM's main control chip, performance does not lose native SATA interface; there are other FL chips, I heard that the heat is relatively large. Due to the need for more USB interfaces, it directly looks at the three USB interface adapter boards and selects NEC chip products. â–¼ express bag, feel the adapter card inside is very light, not large â–¼ Detach an all-white carton without any branding â–¼ In the white paper box, there is a plastic adapter plate. The upper left corner is like the brand NECXG. The upper right corner is the product name Express Card. There is also a USB 3.0 in the lower left corner. â–¼There is also a USB to DC cable on the back for powering the adapter card. In general, the power supply current of the Express interface is about 0.9A. A single USB3.0 power supply is about 1A. Therefore, if you connect multiple devices, it is possible. Need to supply power, directly plug in the USB3.0 interface, DC port adapter board â–¼The yellow cardboard is full of English instructions on the back. This is also the manual. â–¼ plastic everything inside, adapter card, USB to DC cable, caption card â–¼ The adapter card is a 54mm T-type Express Card, the shell is aluminum alloy, relatively thin, with a gold sticker on top â–¼ The back of the black sticker with aluminum alloy shell, watching more than the front tall â–¼ Numerous Express Interfaces. â–¼ On the other side of the three USB3.0 interfaces, the right side is a DC power supply interface â–¼ look flat look, USB interface is not outstanding The needle in the middle of the DC interface is a bit slanted, although it can be inserted, but it is not too smooth â–¼ In the lower left corner of the X230, is the Express Card interface that comes with it. There is a plastic spring baffle, and the adapter card can be directly inserted into the baffle. It is convenient to install. â–¼ must be inserted in the end, after inserting it from the side is such an effect, this row of USB3.0 interface looks really comfortable â–¼ From the top, no heads are seen, no risers are visible at all â–¼ directly insert the card, win10 system, can not install the driver, into the device manager, you can see a USB3.0 controller with yellow exclamation point â–¼This time you need to enter the product driver download page to download the driver, choose to download the NEC uPD720202 driver â–¼ Then install, directly followed by the next step â–¼ After restart, you can see that the yellow exclamation mark is gone and the driver has been installed. â–¼ But still can not be used normally, insert U disk no response, try to discover, X230 notebook bios below Power has a PCI-E power management, will this turn off, and then restart, adapter card can be used normally, plug What equipment has responded â–¼ First test the next U disk, U disk model is SanDisk CZ73, native interface read 142, write 89 â–¼ After transferring the USB3.0 interface, read 91.64, write 45.69 â–¼ Then test the mobile hard disk, the mobile hard disk using a Western Digital blue disk, 5400 rpm, native interface read 110.65, write 89.14 â–¼ After the transfer of USB3.0 interface, read 113.09, write 105.37, no loss of mobile hard disk performance, U disk performance but lost nearly half, it is strange. Multiple tests, changing the interface is similar to the data â–¼ At the same time test, look at the effect, the data and the individual test is similar, meaning that multiple devices at the same time to read and write, it will not lose speed â–¼ test results, the adapter card to a U disk and a mobile hard disk no pressure, performance and individual loss, fully meet my daily use 1, make full use of the X230 Express Card location, transferred out of the three USB3.0 interface, and according to the test performance and the original is not much difference, that is U disk performance gap, do not know what the reason. Fully meet my daily use, very convenient 2, the work of the adapter card can also be, anyway, only exposed three USB interfaces, the rest are inserted inside. USB interface is relatively loose, smooth insertion and removal, if you feel too tight, it is easy to bring the adapter together. Three USB interfaces are used without pressure at the same time. I plug in a mobile hard disk, a CZ73, a G700S receiver, and it is very convenient to use. If it is used in this way, the DC interface is difficult to insert and it needs to be inserted in an oblique manner. 3, continuous reading and writing will feel the temperature of the left palm rest location, the original left palm rest is cool, and now has installed the adapter card and become warm after continuous reading and writing, do not read and write, then it will cool . This chip's adapter card is also good, be regarded as an expansion choice for the notebook with Express Card interface, very easy to use thank you all!
