Hello, everyone. Today, I would like to talk to you about how to choose an Micro SD card. Many people, ah, do not understand why the same capacity is a little expensive and some are a little cheaper. What is the specific difference? More importantly, they do not know how to choose so many brands.
to talk about this topic today, so that your eyes will not be blackened when you buy it. Then I will mention next, for example, 90m, which means 90m per second. I will call it 90m for short. In fact, there are many reasons for the confusion of SD cards, including that manufacturers have different standards for their own brands. Let’s take a look at this table. In fact, there is no need to remember that this table has a rule, that is, the larger the number, the faster the speed. For example, the U3 in the middle is faster than the U1, and then they have recently changed the new standard, which can be judged directly from the appearance. Let’s take a look .
The contacts on the left are in one row, and the contacts on the right are in two rows. A row of contacts is added, so its speed is faster. Of course, this is in addition to the SD card itself. Besides, your device also needs to support this interface, otherwise it will not be able to fully play its speed after buying, but I still recommend you to buy this, because it is a future standard, in the future, ah, you must support this standard when you change a new camera. Next, let me tell you how I choose the S1 card. In fact, there are only two criteria. The first is to look at the speed of reading and writing, and the second is to look at the brand. Then we say one by one that the speed of reading and writing is divided into reading and writing. Reading means reading, that is, the speed of copying photos on your SD card to the computer. If you often shoot activities, If you are very anxious to give the photos to Party A, I think you should pay special attention to the speed of reading, at least 100, and 200 is better.
the speed of reading and writing is the speed of taking pictures and sending them to your SD card. This is more critical. I want to tell you a standard about this. If you like to shoot 4K videos, the speed of reading and writing is more than 30m. Of course, some factories have their own standards. I won’t say more about this. If the speed of the SD card you buy is above 90m, it is already suitable for most scenes. There are more exaggerated 300m cards on the market, which is suitable for very few professionals who like continuous shooting. For example, sports photographers and paparazzi are used.
Of course, the price will be more expensive. Well, the most crucial standard has been explained. Anyway, when you buy it on Taobao, he tells you what kind of card it is and what standard it supports. You don’t have to worry about it. You just ask it two data. One is to read the data. One is that writing data is enough. Next, let’s talk about the brands. I recommend Sony, Shandy, Rexar and Kingston first. Here, Sony is the least cost-effective, and Rexar III is the most cost-effective. I prefer Shandy. Anyway, I haven’t had any problems with it yet. Here I would like to remind you that data is particularly important. So do not save money in this place, and then the SD card technology is actually not so difficult, so ah, there will be a lot of counterfeit goods on the market, we must not be penny-wise and pound-foolish in order to save a few yuan. Here I also mention the capacity by the way, now buy 64 and 128G is the most cost-effective, if you buy 32 or 256, the price of a single machine will be a little higher, I personally think, ah, you even buy summer, then directly on the 128G. When buying, there is another point you can pay attention to, that is, when buying SD cards, some businesses are doing activities to buy SD cards to send card readers, we can choose the businesses that send card readers to buy. All right, don’t do it in vain. Well, that’s all about how to buy an SD card today. If you think it’s useful, please connect the numbers three times. This is the best support for me. I wish you all good health.
