Kioxia EXCERIA PRO SD memory card is currently the flagship model of Kioxia SD memory card, and its performance is also the first echelon in the current market. Let’s test this SD card to see its overall performance through software.
Before testing, let’s take a look at the appearance of this Kioxia EXCERIA PRO SD memory card.
Kioxia EXCERIA PRO SD memory card packaging front
Kioxia EXCERIA PRO SD memory card uses disposable paper packaging. The eye-catching yellow is the representative color of this product in the new design packaging of Kioxia . On the front of the package, you can directly see the body of the Kioxia EXCERIA PRO SD memory card. At the same time, you can also see the various speed standards, models and capacity versions supported by the package.
Kioxia EXCERIA PRO SD memory card packaging back
You can see the seal of the quick disassembly package and the related parameter information of the Kioxia EXCERIA PRO SD memory card on the back of the packaging. For example, the maximum read speed is 270MB/sec, and the maximum write speed is 260MB/sec. Supports the camera’s high-speed continuous shooting, 8K video shooting, and resistance to cold and heat.
Kaixia EXCERIA The front of the PRO SD memory card
Kioxia EXCERIA PRO SD memory card body is black, and the front label is the same as the package, which is eye-catching yellow. Various performance standards LOGO are also printed on the label surface. Such as UHS-II, V90, U3, Class10 and so on. This evaluation is the 128GB version, and the actual usable capacity is 119.2GB. There are also 64GB and 256GB versions to choose from.

The production information code is printed on the back of the card body, and we can see that the card is MADE IN JAPAN. At the same time, the biggest difference between UHS-II and UHS-I can be distinguished from the back of the card, that is, UHS-II cards have two rows of gold fingers.
Software performance test
ATTO Disk Benchmark
ATTO Disk Benchmark is a disk/network performance test tool produced by ATTO company, the software uses 4MB The test package is 0.5K, 1.0K, 2.0K until 8192KB for read and write tests. After the test is completed, the data is expressed in the form of a histogram. It illustrates the impact of different file size ratios on disk speed.
ATTO Disk Benchmark test results
From the test results, we can see that the performance of Kioxia EXCERIA PRO SD memory card basically reached its peak when reading and writing files of 256KB or more in length, reading 258MB /Sec, write 225MB/sec. Although there is a certain gap between the official nominal 270 MB/S read and 260MB/S write, the reason for this gap is generally on the USB interface of the card reader and the test computer, which will not be felt in actual use. There is an obvious speed difference.
CrystalDiskMark is a tool for testing computer hard disks. The simple and easy-to-operate interface allows you to test your storage devices at any time. This software can detect the random read/write speed of the hard disk, as well as the continuous read/write speed. Test random 512KB, 2KB, 4KB read/write speed, etc., users can use this to distinguish the performance and quality of the disk.
CrystalDiskMark test result
Kioxia EXCERIA PRO SD memory card in the CrystalDiskMark test, the maximum read speed is 256.7MB/s, the maximum write speed is 218MB/s, the test value is basically the same as the ATTO Disk Benchmark test result. The official nominal value is close.
HD Tune Pro
HD Tune Pro is a hard disk performance diagnostic test tool. It can detect the transfer rate of the hard disk, burst data transfer rate, data access time, CPU usage, health status, temperature and scan the surface of the disk. In addition, the firmware version, serial number, capacity, cache size, and current transfer mode of the hard disk can be detected in detail.
HD Tune Pro file test results
HD Tune Pro test can draw the internal transmission rate curve of the hard disk, and can also display the dot matrix of the test sample in the seek time test, which is more intuitive. The data obtained from the software test is basically the same as that of ATTO Disk Benchmark. It can be seen that the official performance of the Kioxia EXCERIA PRO SD memory card is relatively accurate.
Practical application test
Compared with the previous two years, with the development of cameras, the current performance indicators of flagship digital cameras of various brands are very high, and continuous shooting takes 20 pictures. For video shooting, 4K60p with high bit rate is basic, 4K120p, 6K and even 8K have already appeared. For these flagship digital cameras, the UHS-II SD card is the standard configuration to ensure camera performance.
UHS-II standard SD card necessary for flagship digital cameras
Kioxia EXCERIA PRO SD memory card has a maximum read speed of 270 MB/s and a maximum write speed of 260MB/s. It is suitable for these flagship products, and can exert their maximum performance, high-speed continuous shooting without pressure.
Editor’s point of view
In terms of speed, Kioxia EXCERIA PRO SD memory card is one of the fastest SD memory cards on the market.
