Advantages: speed (compared with 2.0), compact size, and low price;
Inadequate: Inconvenient to install behind the chassis (expandable front panel, no extension bracket), general materials, drive too slag (random drive speed is not as automatic as WIN10)
Purchase suggestion: If the desktop does not support USB3.0, there will often be a need for data copying, based on the low price, just need to recommend the purchase .
In the last test of the following U disk, I found this U disk speed is slow:
The suspicion is not a notebook problem. In order to figure out whether it is U disk speed, or computer problems, so I decided to upgrade my old desktop to USB interface, in Jingdong entered this:
Second, out of the box and appearance of the picture:Packaging
back
Unpacking and seeing the electrostatic bag
Family portrait (please disregard the left-bottom doll)
Expand the card body, there are few components above, there are qualified inspection labels, the components used are more general (such as capacitors are ordinary capacitors)
Power connector is marked with stickers
Gold finger new
No part on the back
4PIN power supply interface
This blue interface is the front panel USB3.0 expansion interface, but this product does not include front panel expansion accessories
Expansion scenarios are as follows (not included in the front panel expansion shelf) (this picture is a network download)
Two blue USB3.0 interfaces
Please ignore my old antique machine, and the messy lines, after all, lazy, after all, this chassis is the price of cabbage. . .
Unscrew the chassis screws
The whole picture of the motherboard (please ignore the web-like wire)
Installed in the motherboard PCI-E 1X interface, the motherboard is MSI's 880GM-E41, the pursuit of cost-effective, it seems to be about 500 to start, enter the end of 2010, has been stable operation of more than 5 years, and value.
Remove the back panel of the chassis (do not know how to call)
Press the alignment interface down to place
Senior PIN power supply
The installation is complete
Use the same U disk (see the next card: SanDisk CZ73) first test in the USB2.0 interface, and then test in the USB3.0 expansion interface (However, this U disk is relatively slow, U disk quality itself will become a bottleneck , For reference only. If you use a solid-state mobile hard disk for testing, you can objectively reflect the speed of the USB expansion card. Limited conditions, please understand.
The test computer configuration is as follows laptop (right) and desktop (left)
Utilize CDM software to use USB2.0 (right) of the same U-disk on the same machine and this expansion card USB3.0 (left)
Using the same U disk in the desktop development card USB3.0 (left) interface and laptop USB3.0 interface using CDM software speed
Expand the actual file copy of the card: write a movie with a size of approximately 1.42G to the U disk above , which takes 47 seconds and 40 seconds; after the speed decreases, approximately 20M/S (Because the SanDisk CZ73 uses the TLC simulation SLC mode, the capacity of the simulation area is 1GB, so 1G speed can reach 80-90M/S when starting to write; read out the same file : read a movie about 1.42G in size, it takes 20 seconds and 65 seconds; but read speed on the expansion card Compared to notebooks faster (notebooks only 38M/S), expansion card reaches about 67M/S (nominal reading speed 130M/S)
Advantages: speed enough (a lot higher than 2.0), small size, low price;
Inadequate: Inconvenient to install behind the chassis (expandable front panel, no extension bracket), general materials, drive too slag (random drive speed is not as automatic as WIN10)
From a practical point of view, extending a USB 3.0 to an old desktop computer has a certain degree of improvement for file transfer, and it is worthwhile for children's shoes that need to copy files frequently. However, generally, there are office computers for copying documents, and less for home computers. Business desktops in the office are generally branded machines, and their ability to expand is limited. Therefore, the real use scenarios of such products are relatively obscure.
If I raise a video card again and change the solid state, my antique machine can also "sew up for another three years."
Oh, yes, the chaotic toys are sons. He won't be smashed by me.
Well, this is 20 days in the draft and it's finally done. It's lazy! ! !
Only when they are evasive, they have limited conditions, and they are inevitably mistaken and missed.
You will be worthy friends, and will! !
