Gksuu Card reader

For the longest time, I had a novel thumb drive (an actual silicone thumb with a memory stick built in), but I was tired of people pulling it out and saying "Wow, this is really cool". The best case is annoying, and the worst case is that I will damage the files, so I have been looking for a more cautious way to save the briefcase of the documents during the trip. I tried San-Disk Cruzer-Fit. Although it has been working for several years and has grown old, it is slow and inflexible (it can only be used in a USB slot). I decided to use a Samsung 256GB micro SD card and this small card reader. The micro SD card format is fast and flexible (ie: I can use it on devices other than computers with USB slots), and when used with a laptop, the card reader is much smaller than Cruzer-Fit.I tried to use the micro SD card for the half-height SD card adapter sold online, and it is suitable for newer ultra-thin laptops, but the quality of these sockets is poor, and the delicate golden finger contacts will quickly get stuck and completely Invalidate.This micro SD card reader fully meets the requirements. Although not invisible (especially with bright blue LEDs), it is very small, extending about 5 mm from the edge of the laptop. It also has a square outline, so it is unlikely to get stuck on the sleeve of a laptop or school bag. Finally, it is very difficult to insert the USB slot, which means you have to remove it. Unable to remove the reader and Micro SD card at will, which solved my initial problem.Win-win-If you have similar needs, I will recommend this product and will buy it again, and I am very satisfied with the price.

First, let's talk about size.This is the smallest memory card reader I have ever held.If your wireless keyboard or mouse uses a modern nano receiver, you already know the approximate size of this card reader.It is difficult for me to really convey how tiny it is. You will need some way to avoid losing it.Fortunately, there is a small cutout on the top so you can attach a lanyard.If you want to carry it in your pocket, it is recommended to put the memory card in it to prevent dust and fluff from entering the memory card slot. The included port cover will do a good job on the USB port.Now, let's take a look at the rest of the reader and see how it functions as a memory card reader. You know. The reason for its existence.>Fit and trim.The reader fits the USB port of a computer very well. A bit comfortable.You will need the small ribbed handle on the side to really hold it.First, you can tighten the card suitable for the SD card. I find myself worried about whether to crack the memory card when I insert it, so please be careful. At least it will not fall! Use will make it loose.Due to the close fit, removing the memory card is actually a bit difficult. You need nails or something similar.The bright blue LED below the plastic translucent top indicates activity. When everything is detected, it will stay on and then flash quickly during the event.performance:This is a USB2 memory card reader. This thing will not brag.In other words, the average speed of downloading videos from a memory card that I am not a GoPro at all is 23.5MB/s. The read speed of the memory card I used for testing is 48MB/s. I'm not sure if the limit of the reader itself has been reached, or the actual limit of USB2. For reference, I am using an old PC.The writing speed reached 13.1MB/s more easily, but I am pretty sure I am reaching the limit of the memory card, not the limit of the reader.
