We have tested and disassembled the prestigious CFexpress B memory card for you before, and this time we will introduce his CATALYST series "Su Feng" (gold) SD card.
We got four products * * *, namely: 128GB UHS-II V90 SD card, 128GB UHS-I V30 SD card, 256GB UHS-I V30 microSD card and SD/microSD card reader compatible with UHS-II and UHS-I overclocking cards. The nominal working temperature of the memory card is -25 to 85, and the warranty period is 5 years.
The nominal reading speed is 300MB/s, and the writing speed is 280MB/s, which conforms to the V90 speed class. It can record 4K 60p XAVC S-I video on Sony α7IV until the card is full.
With the original card reader, the measured writing speed is up to standard, and the reading speed is slightly higher (about 3 10MB/s). HDTUNE continuously writes about 2GB of random data, and the whole process is kept above 200 MB/s.
On Sony α7IV, there are about 52 10FPS (electronic shutter, high-speed continuous shooting+,compressed RAW) in continuous shooting. The total number of files is about 1.87GB, and the average writing speed is about 214mb/s/s.
On Canon EOS R7, there are about 45 30FPS continuous shooting (electronic shutter, high-speed continuous shooting+,lossless compressed RAW). The total number of files is about 1.43GB, and the average writing speed is about189mb/s/s.
The continuous reading of the whole disk measurement is stable.
The nominal reading speed is 180MB/s, and the writing speed is 150MB/s, which conforms to the V30 speed class. Reaching the first-class level of UHS-I overclocking card at present can reduce the transmission time to the computer and improve the work efficiency.
Using the original card reader, the actual reading speed is up to standard, and the writing speed is slightly higher (about 162MB/s). HDTUNE continuously writes about 2GB of random data, and there is no obvious speed decrease in the whole process.
On Sony α7IV, there are about 29 10FPS (electronic shutter, high-speed continuous shooting+,compressed RAW) continuous shooting cards. The total number of files is about 1.03GB, and the average writing speed is about 80mb/s.
On Canon EOS R7, there are about 43 30FPS continuous shooting (electronic shutter, high-speed continuous shooting+,lossless compressed RAW). The total number of files is about 1.35GB, and the average writing speed is about 77.7mb/s.
On fuji X-S 10, 8FPS (mechanical shutter, lossless compression RAW) continuous shooting card is around 19. The total number of files is about 584MB, and the average writing speed is about 58.6 MB/s.
You can record 4K 50p IPB 10 video (340Mbps) for more than 15 minutes on Canon EOS R7, and 4K 25p ALL-I 10 video (470Mbps) for more than 15 minutes on Canon EOS R3.
The continuous reading of the whole disk measurement is stable.
As a -I overclocking card, we also tested its compatibility with other card readers, and the measured reading and writing performance of the new Lei card reader can also exceed that of the standard -I card.
The nominal reading speed is 175MB/s, and the writing speed is 150MB/s, which meets the speed class of V30. At present, the devices using microSD cards are mainly sports cameras and drones, and there is almost no demand for high bit rate writing. Therefore, the test focus of microSD card is reading speed and reliability.
When matched with the original card reader, the measured reading speed meets the standard, and the writing speed is slightly higher (about 164MB/s). For random writing of 2000MB, HDTUNE is kept above125mB/s..
On Sony Xperia Pro-I, using CPDT test, write about 57MB/s and read about 90 MB/s. ..
On insta360 ONE RS, record at 4K50p until the fuselage is overheated and automatically shut down.
It is measured that the whole disk is stable in continuous reading, and the compatibility of the card reader is the same as that of the UHS-I card mentioned above.
Finally, talk about this card reader. Adopt USB-A port, support UHS-II SD card and UHS-I overclocking SD card, which can be read by dual cards at the same time, and the speed is basically unaffected when dual cards are operated at the same time. In addition to its own UHS-I SD card, the actual measurement can also play the best reading performance of Sandisk and Kingston overclocked UHS-I SD cards.
Although Zhiyu is still a new face in the field of civil memory cards, it is indeed a senior manufacturer in the storage field. Not only has a rich product line, but also has in-depth cooperation with many movie camera brands at home and abroad. As the saying goes, these four SD card storage products have reached the first echelon in the performance of similar products, providing a new choice for enthusiasts who pursue high performance.
