Mobile phone capacity expansion sharp tool Weibo USB3.0 OTG USB flash disk test | Ainuo machine - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

More and more mainstream Android phones support OTG (On The Go) technology. Through it, we can enable mobile phones to read USB disks and use USB devices such as keyboards, mice, and handles. For the convenience of mobile phone users, many manufacturers even introduced OTG USB flash drives with their own microUSB interface. What we are testing today is an OTG USB stick launched by Verbatim Weibo. Its biggest feature is that it supports USB 3.0 technology.

Weibo named this product "OTG flash disk", which is a disposable paper package marked with the product capacity and support of USB 3.0 technology ▼

There are multi language descriptions on the back ▼

Open the package, we can see that this OTG flash disk has a black brushed plastic surface. It can be seen that there is a microUSB interface by default, through which we can connect the mobile phone ▼

Close up of back, also black brushed plastic ▼

There is a push rod at the top of the flash disk. It can be seen that it is pushed to the left ▼

Let's pull the push rod to the right ▼

Push down the middle to put away the microUSB interface. At this time, the entire USB stick has no exposed interface, which is convenient to carry ▼

Pull the push rod to the far right, and a USB 3.0 interface will appear, marked with the capacity of the flash disk ▼

Since the OTG USB flash disk can be inserted into the mobile phone and computer for use, our test phase here is also divided into two parts. First, we insert the OTG flash disk into the microUSB interface of the mobile phone, as shown in the figure ▼

After inserting the phone, you can find the information of the USB flash drive in the system settings. This USB flash drive we tested Nominal capacity 16G, actual capacity 14.42G ▼

Generally, mobile phones that can support OTG technology will automatically open their own file manager after inserting the OTG flash disk. At this time, we can easily read and write data in the OTG flash disk ▼

We also use the speed measurement application A1 SD Bench to test Weibo OTG flash disk Read 34.66MB/s, write 11.85MB/s ▼

The following is a horizontal comparison chart of OTG flash disk, eMMC flash memory and microSD card. It can be seen that the OTG flash disk in this test has a slight advantage over the ordinary Class10 microSD card in terms of reading and writing speed, but the gap is not large. Compared with some high-end microSD cards Compared with eMMC flash memory, the speed of this OTG flash disk is too slow. Of course, the speed of reading and writing here is also limited by the speed of the mobile phone's microUSB (USB 2.0) interface ▼

Finally, we were in the bar early. This flash disk was inserted into the computer through the USB 3.0 interface, and the ATTO Disk Benchmark was used for speed measurement. The measured data was read The fetching speed exceeds 81MB/s, and the writing speed exceeds 10MB/s , the reading speed is satisfactory, while the writing speed is slow ▼

From this test, we can see that this OTG flash disk of Weibo can really achieve both performance and ease of use. The dual interface ensures that it can adapt to more devices and enable some mobile phones without tf card slots to achieve the purpose of expanding capacity. It can also be connected to the USB 3.0 interface when used on the computer, greatly improving the reading speed.
