Students started the small ant sports camera. At that time, the production capacity of flash granules was still very good. The prices of Samsung EVO+, 32GB, and U1 TF cards were only in the early 50s. With the shortage of flash memory in the second half of 16 years, such TFs The price of the card went up. For a generation of small ants that can only shoot 2.7K, 30FPS video for the sports camera, U1 level Samsung EVO is sufficient.
After working, I started Gopro Hero 5 Black, which is a sports camera that can shoot 4K 30FPS video and continuous shooting 30 1200W pixel photos, which brought a lot of pressure to my Samsung EVO. At the same time, 32Kbytes of storage space can record up to 1 hour of 4K video also let me consider it is time to start with a larger capacity, faster TF card. I chose to go. In the end, I tried Toshiba’s Exceria Pro M401 for 269 yuan. Although it was a bit of a pain, I looked at the price of U3-rated Samsung Pro+ for almost 400 yuan, plus I used to use it. Toshiba's Q300 SSD has a good impression and eventually chose Toshiba.
Toshiba (TOSHIBA) 64G EXCERIA PRO TF (micro SD) ultra-fast memory card U3 R95M/S-W80M/S support 4K shooting 269 yuan high-speed TF card, 4K camcorder best partner Jingdong direct link 
The appearance of this Toshiba Exceria Pro M401 memory card is a combination of white and gray. It looks low-key on the outside, but it has very strong performance. At the same time, an SD card adapter is also included with the card, allowing this TF card to play its role directly in more locations. The donated one-year data recovery software will also provide users with a more secure experience.
For this review, I will examine the read/write speed of Toshiba Exceria Pro with two types of read/write devices:
- Black Dog 5
- Laptop with MLC SSD
The first is black dog 4K video writing and high-speed continuous shooting. Under good light conditions, Black Dog 5 can write up to 60 Mbps bit rate, about 7.5 M/S after conversion, which only uses a success rate for Exceria Pro that can write continuously over 75M per second. , every second after the end of shooting is stored.
"4K video, you have five slags." Exceria Pro said.

Of course, in addition to the 4K video recording, another feature of the Black Dog 5 also puts a higher requirement on the performance of the TF card - the continuous shooting mode. In this mode, press the shutter button, you can take a set of 1200W pixel photos in one shot according to the set total time and number of shots. You can shoot 30 such photos in one second at the fastest. In a place where there is plenty of light and where the image is clearly visible, such a photo will occupy about 4M of space, that is, taking 120M of photos in one second.
In this mode, the advantage of Exceria Pro's ultra-fast writing is magnified. After each shot is completed, the screen will only show the words “Saving†for 3-4 seconds. Ordinary TF cards need to be written for 10 seconds or even longer. Exceria Pro is a good choice for people who do not want to miss the moment because they write slowly.
Next is the test on the computer platform, I have not used the desktop for many years, has long been the use of notebook computers for office, and now in the use of notebook computers is Lenovo's Y50, in order to enhance computer performance, the author of this notebook It was upgraded with the addition of solid state drives and memory. The current configuration is as follows:
In everyday use, when we use a laptop to read and write files to Exceria Pro continuously, the speed is as follows. All video and photos filled with 60GB of storage space need to be cut to SSD for 11 minutes at an average speed. 83~87MB/S floating. When writing a 2GB movie to it, the writing speed fluctuates from 73 to 77MB/s, which is a little different from the speed of official propaganda. It is already very close. After all, the full speed situation is very ideal and the normal state can be achieved. This speed is already very conscience.
Later, I also used the Crystal Disk Mark software to test the Exceria Pro. This software can generate a large number of 4K files, which is very good for testing random read and write capabilities of memory cards. It is very necessary for those friends who install the APP on the TF card to simulate reading and writing when using the mobile phone everyday. Through the following test results, we can see that the 4K random read speed can reach 7M/S, which can meet the requirements of current mainstream mobile phone APP operation files.

About cost performance
For such top-level TF card readers, the price/performance ratio is definitely not an indicator that buyers are concerned about. Users who value more value for money will focus on U1-level memory cards. For Exceria Pro users, the price is not a problem. With flash memory prices skyrocketing, the price of Jingdong's 269 yuan is more conscience than some similar products (such as Transcend U3M 64GB U3, reading 95M, writing 60M, priced at 359).
At a time when the price of flash memory chips is rising, the Toshiba Exceria Pro M401, priced at 269, is an excellent TF card with excellent performance and low price. The five-year warranty provided by Toshiba Storage will also provide us with more confidence in the use of the Toshiba Exceria Pro M401. Experience. There are performance requirements, and friends who are not particularly sensitive to the price can buy it as a loyal companion to your sports camera.
