Evaluation of SD memory card of Armor Man (formerly Toshiba Storage), a good helper of 4K photography

With the popularity of 4K devices, many video writers gradually began to shoot 4K materials.

So, what are the benefits of shooting 4K material?

First of all, 4K material has higher definition, sharper picture and richer picture details.

Secondly, when the video is synthesized twice, 4K pictures can cut 75% of the material lossless.

Third, it is more convenient to adjust later.

4K is good, but it brings higher image quality and more data. At this time, it is a hard demand to improve the storage capacity and reading and writing speed of the memory card. Especially in the reading and writing speed, if the writing speed of the memory card is low, the storage speed can't keep up when shooting, resulting in the camera crashing or waiting for a long time. This kind of shooting experience is very bad, and it is easy to miss the shooting of wonderful pictures. Therefore, it is necessary for photographers to be equipped with a high-speed and large-capacity memory card.

Recently, I received the memory card SDXC UHS-I, formerly known as Toshiba Memory. The memory card has a maximum reading speed of 100MB/s and a maximum writing speed of 85 MB/s. It supports technical protocols such as V30, U3, class 10, and the storage space of 256GB is enough to meet the demand of 4K shooting.

Toshiba Storage was officially renamed as "KIOXIA Armored Man" in June+10 last year. This name combines the two meanings of "memory Kioku" in Japanese and "value Axia" in Greek, from which it is not difficult to see the value of storage devices in preserving our precious memories. It's not just a name change. It turns out that Toshiba has original granules and technical advantages in NAND flash memory, and Iron Armor has also inherited it.

Not much to say, now let's take a look at the actual performance of this SD.

Appearance appreciation

This SD package adopts magenta color scheme, which is highly recognizable among many memory cards.

According to the information given on the package, this SD card supports V3, U3, A 1, Class 10. These parameters show that the SD card meets the requirements of 4K ultra HD shooting.

On the back of the package are more detailed data and specifications, which show product information such as supporting 4K shooting, maximum reading speed, maximum reading and writing speed, and approximate available capacity. It is worth mentioning that the memory cards of the armored forces are all produced by Japanese factories.

EXCERIA PLUS SDXC UHS-I memory card can be used in the environment of -25 degrees to 85 degrees, and it also has the function of preventing X-rays. I can also complete the shooting task well in some special harsh environments. Although I may not have experienced such an extreme environment, for professional photographers, such a heat-resistant and frost-resistant memory card is definitely an excellent choice.

The memory card EXCERIA PLUS SDXC UHS-I still uses the UHS-I protocol, and even some cameras that do not support UHS-II can shoot 4K materials. The reading speed of 100MB/s and the highest writing speed of 85MB/s can provide a smooth ultra-high definition shooting experience.

Literacy test

Next, through the software test, let's see how the data processing performance of Iron Armor EXCERIA plus SDXC UHS-I memory card is.

Under the Win 10 system, through the software test of DiskMark, we can see that the highest reading speed is 92.45MB/s and the writing speed reaches 88.44MB/s, which basically conforms to the official propaganda data and the speed performance is quite good.

ATTO disk benchmark data is similar.

After professional software testing, insert the SD card into the camera for the actual shooting experience. For photographers, high-speed memory cards can process photos faster, generate photos and videos in a shorter time, and capture wonderful pictures faster.

In the process of use, a number of 4K videos were recorded, which is quite good in terms of speed. And the storage space of this card reaches 256G, which is absolutely enough.

The shooting material is 4K resolution, MP4 format and H264 coding. The whole shooting process was very stable, and there was no jam. The file generation speed is very fast, and the photos are almost seconds. It's really made by Toshiba.

A 4K video of about 1 min was shot with a capacity of 846MB. The huge amount of data requires not only the capacity of the memory card, but also the writing speed. EXCERIA PLUS SDXC UHS-I memory card can display video smoothly and without jamming, which completes the data writing task well.

For journalists who often run various activities, especially sports events, it is necessary to use the high-speed continuous shooting function to capture all kinds of wonderful moments, and dozens or even dozens of photos may be captured in a short moment. This requires that the writing speed of the memory card is very high.

The camera used in the test is Sony α6000, and the accuracy of the photos taken is adjusted to the highest quality. The highest speed continuous shooting can take 30 photos without getting stuck, and it takes about 6 to 7 seconds from the completion of shooting to the completion of photo-taking. This data writing speed is quite fast. The writing time of 30 photos of continuous shooting and my own SD card is generally more than 10 second.

The material import speed is also good after shooting. Under the USB 3. 1 interface, the speed of 90MB/S is close to the officially marked speed, and the previously shot material can be quickly copied to my computer hard disk.

As can be seen from the above use, the memory card EXCERIA PLUS SDXC UHS-I performs very well in reading and writing. In the shooting of 4K video, the high-speed writing speed finally provides stable video material, and there will be no jamming and screen display.

At the same time, UHS-I protocol is quite friendly to some old cameras that support 4K shooting. For professional photographers, such a high-performance and stable memory card is an ideal companion for their cameras.
