First of all, the picture on the home page is online, too lazy to shoot.
Before writing a usb3.0 U disk speed comparison, the response is relatively strong. This time a common SD card speed comparison.
Because the work requires many cards, it is often used to buy a card for use. There are many SD cards in the hand and you can use it to lose. This comparison can only be a card that is currently in your hand.
The type of test card can not cover all brands. The principle of purchasing cards is based on the principles of easy use, sufficient use, and cards used for work. The most important thing is to stabilize the cards. Those tall brands and models do not participate in the comparison, the local tyrants do not come to the sun in the comments, there are more pieces of your card, you have money, you cattle X.
1,
Shiyan This brand of memory card may not be so famous, in the computer storage or factory.
The price of this card is more than 100, the card is more than 30M, the card is 88M, and the price of more than 120 is more value than 1, 2 years ago. Now it is not so great value.
2, SanDisk's cheapest TF card, 16G, is basically also used for driving recorder, write about 10M card, reading card 75M.
3, with the above card, plus a card sleeve, the speed did not decline, that completely replace sd card is completely feasible with tf card plus card sets
4,
An upgraded version of the Samsung sd card, Samsung has always claimed that the sd card is a three defense, speed down 25M and 90M. Very worth recommending
5,
This is Samsung's old orange card, there is no evo, now out of orange cards are with evo. Write the card 20M reader card 45M. Remember to be more than 40 for 50 or so. It's not worth it now 
6, Samsung is now difficult to buy SD card, basically TF card, this card I strongly recommend
7, Samsung's high-end SD card, remember when Suning bought 99, really arrived
8,
Lexar, the brand is tall, expensive, performance is a bit of advantage, I think it is not worth, this card is sent by the DJI plane.
Written card 25M reader 90M, regular price more than 50 pieces, other home 32G price, it home 16G, TF card also need to forcing
9,
This is a very old Kingston sd card, and it is not easy to buy it now.
10, Kingston's very old card, for reference, it is now used as a loading system
11.
Toshiba old low-end card, write card 60M reader 90M
12,
Toshiba's old high-end card, write 90 90 card reader,
13,
Toshiba's new low-end card, write 32M card reader 90M, this is lower than the above green card.
14,
Maxell card 64G version of the new card, the shell is blue and black, the new version of the card has shrunk significantly, the old version of the card's high reading speed is not, writing only about 16M, readers only about 45M, regular price of 99 yuan, this It was bought for 45 dollars in Central Asia, but in the current market, 99 is not worth buying, and 45 is buying value.
The old version of the card can not be remembered to write card is about 25M read card 25M. 3 4 years ago to sell 145. Almost God card.
There are not many varieties. Basically, it is enough to take a picture. Shooting video 720p 50P, 1080p 50P, 720P 120P video can be perfect shot.
If you do not have special 4K video shooting requirements and do not have the requirement of continuously patting tens of jpg photos, it is more appropriate to buy a tf card card holder with more than 20M reading cards and over 80M reading cards.
According to the current market price of various cards, 64G price is less than 100 yuan, 32G is less than 60 yuan, Samsung's evo 64g red card and Toshiba's low-end red card is a more economical choice. Toshiba seems to have only sd cards, Samsung is basically a TF card, and the two brands have little conflict. However, Samsung claims to be the three defenses. It should have certain stability and reliability. In short SD card recommendation to buy Toshiba brand, TF card recommended to buy Samsung brand. Although Samsung was a bit shameless recently because of note7, it is still worth recommending. As for SanDisk, now the most common SD card brand, I don't like it. With so many years of memory cards, there are several bad ones. All of them are SanDisk's, and SanDisk's speed is not faster than others, but it must be more expensive than others. Buy it!
In fact, there is really no need to pursue the kind of card that is written with more than 80 reading cards and more than 80 cards. The meaning is really nothing.
