To say that the little friends are completely useless equipment and design, the outdated USB storage disk and the USB interface on the router can definitely be ranked. Are they really “waste” or uniform design attached? In fact, as long as the two are combined, the “residual heat” is used, and the “NAS” purchased 0 yuan is not fragrant?
The editor first talks about the USB interface of the router is not small. In addition to storage, it can also connect to printers such as printers, but this is another matter. Let’s talk about it later. In addition, pay attention to the router USB interface standards. Some are mainly prepared for a peripheral peripheral of printers. Do not consider the mobile hard disk if you do n’t run. Some of them have two USB interfaces. This is not only for speed, but also because USB 3.0 is stronger and stable.
There are three main types of USB storage disks, moving hard disks, mobile SSDs and U disks. The router also has two modes: Wi-Fi connection and wired connection. Let’s take a look at their differences. The first is on the computer to see their “extreme speed”. Everyone should be able to guess that it must be the strongest to move SSD, and then mobile hard disks and U disks.

Then try these mobile storage on the router. Gigabit wired+USB 3.0 is the most ideal connection state, but the speed of mobile hard disk and mobile SSD is still completely “flattened”, and the read speed of the U disk has dropped a little. As for the speed of writing, it seems that 60MB/s is also the limit, and even the U disk itself is not high.
The common notebook computers and some desktop are used to connect the router with Wi-Fi, and we try this way. Here is a relatively high 5GHz band connection. The theoretical rate should be 2.4Gbps, which is not worse than the wired network. But the actual and read -writing speed is not like this, and it is obviously declined again. The reason is very simple. The “professional” of the router is the network, especially the wireless network control. When the high -speed wireless network access, most of the processing capabilities come to control the network. Of course, the storage and reading treatment is even worse.
Speaking of “professional”, finally see what the real NAS performance is. Affected by the speed of the network, of course, the NAS hard disk cannot be as fast as the hard disk of this machine, but it is only affected by the network speed. Compared with the connection speed of the device, the router connecting the Gigabit port of the NAS is the bottleneck, so wired and high -speed high -speed speed The reading and writing speed of wireless connection is basically the same, and more than 100 MB/s is of course more fragrant. But … think about spending, I feel that the cost -effectiveness of the router USB is still good. What do you say?
