With the latest cameras, you can capture still footage at higher speeds and shoot higher resolution videos. Memory cards with fast, high-read/write capabilities have become more important than ever. Normally, "no memory card included" is a product sales practice, including cameras, dash cams, monitoring and other equipment need to be matched with the correct memory card by the user.
This time, I tested the PRO professional high-speed memory card from YMTC Zhizhi, and used this as an example to tell you why you should choose a memory card with faster read and write speed.
About the state
ZHITAI is the only consumer-level retail storage brand under YMTTC, and has previously released many solid-state drive products, which have been recognized by a number of consumers, and the brand strength is absolutely very top.
Product Information
Included in the package is a microSD (TF) card and comes with an original accessory card holder, the SD adapter.
At the same time, the outer packaging indicates the memory card capacity, read and write speed, and crystal stack: 512GB, read speed up to 170MB/s, write speed up to 120MB/s. The Xtacking ®® architecture is a unique technology of YMTC, which places the peripheral circuits in the memory cell, has a higher storage density than traditional 3D NAND, reduces the chip area by 25%, and realizes wafer bonding through billions of vertical interconnect channels (VIA), effectively improving the packaging density and trusting the quality of the original factory. And through U3, V30, A2 and other standard tests, the read and write performance is guaranteed.
In terms of protection, Zhizhi PRO professional high-speed memory card has the characteristics of cold resistance, heat resistance, water resistance, impact resistance, shock resistance, drop resistance, anti-static, and X-ray resistance, and the gold finger can be plugged and unplugged 10,000 times, which is enough to cover the product life cycle, and the official also provides lifetime warranty services.
Disk read/write speed test
When it comes to memory cards, performance and stability are the things that make the difference in consumer decision-making, and here I tested it with the help of several disk test software.
First of all, take a look at the performance of the Zhizhi PRO professional high-speed memory card in the CrystalDiskMark test, using a microSD card reader that supports DDR200 mode, connected to the computer PC, the maximum write and read speed of the memory card appears at 1GB file size, and the measurable write speed reaches 168.43MB/s, and the read speed is 119.05MB/s, which is almost no different from the official nominal value.
Next is the ATTO disk benchmark test, on the 64KB size of the transfer file, you can see that the read and write speed has come to a very fast value, to the 64MB file, the read speed reached 160.75MB/s, the write speed reached 123.67MB/s, which is also basically in line with the official nominal value.
Here I also performed a large file read and write test, and I can see that in the actual file transfer, the write speed can reach 109MB/s stably.
THE READ SPEED REACHED 156MB/S, WHICH IS NOT MUCH DIFFERENT FROM THE RESULTS OF THE PREVIOUS TEST SOFTWARE.
In addition, I used the AJA System Test, a test tool that measures the read and write speed of the storage device and simulates the workflow of a specific video frame size and frame rate to test the performance of the device under a real-world workload, and I can see that the read and write speeds are also stable at 160MB/s and 110MB/s performance levels in the case of simulated 4K video recording.
Hands-on experience: Reading and writing are silky smooth with no lag
In addition to video, another thing that makes the memory card feel more strain is continuous shooting, but the Zhizhi PRO professional high-speed memory card can still easily do it. In the test, using a high-pixel camera for shooting experience, the volume of a single photo is usually tens of MB, turn on the highest speed continuous shooting mode, shoot dozens of photos in a row without storage pressure, and basically do not have to wait to read the cache, you can continue to operate the camera.
The continuous photos taken by the camera are generally stored in the cache of the fuselage first, and then written back to the memory card after the shutter is released, which can be seen from the display screen, after taking multiple high-quality photos in a row, the speed of writing back to the memory card is also very fast, very silky, no need to wait.
Therefore, the performance of this storage speed can meet the needs of the vast majority of professional users in continuous shooting.
At the same time, when you view the photos you just took continuously, the whole process of slicing is loaded instantly, and there is no cache delay, which means that the reading speed is also very fast, and the actual experience is full of points.
Including the video shooting mentioned above, here I also tested it with the camera, recorded a video for a period of time, after the shooting started, the storage read and write indicator of the screen quickly began to flash, including the final write-back is the same, the performance is very fast.
You don't have to wait for the loading process to play back the video you just shot, and you can play it back instantly without the slightest delay when you perform double-speed playback.
Protection: Multiple layers of protection make storage more secure
In addition to excellent performance, the Zhizhi PRO professional high-speed memory card also has excellent protection capabilities, it has comprehensive multiple protection capabilities, and also supports a lifetime warranty, bringing users a strong guarantee, so that they can use it with peace of mind.
Zhizhi PRO professional high-speed memory card has the characteristics of waterproof, high and low temperature resistance, X-ray resistance, magnetic resistance, impact resistance, drop resistance and wear resistance, etc., basically covering most of the scenarios of our daily use.
Especially for professional photographers, the footage that is hard to shoot every time you go out is very precious, and if the footage is lost due to the poor protection ability of the memory card, it will cause huge losses. In particular, the memory card is broken, wetted by rain, demagnetized, damaged by X-rays, etc., which are common and important culprits that cause SD memory card damage. With the PRO Pro high-speed memory card, our data security is guaranteed to the maximum.
Review
The PRO Pro Pro has powerful performance, with excellent storage speed and read and write speed, which can fully meet the needs of users for photo storage, video recording and continuous shooting storage. In terms of protection, the Zhizhi PRO professional high-speed memory card also has obvious competitiveness in the industry, and supports a lifetime warranty, which is very intimate.
Another very important point is that the price of the Zhizhi PRO professional high-speed memory card is very affordable, and it is also one of the cost-effective SD memory cards, so whether it is a photographer or a photography enthusiast, this product is very suitable. If you're looking for a memory card, you might want to give it a priority.
