CHIPFANCIER CFexpress Tpye A 4.0 Memory Card VPG400

A: Gold CFA4.0 adopts PCle4.0 protocol, which doubles the bandwidth compared to the old CFA card, and together with the new master control and FLASH can run at higher frequency, so the performance is greatly improved. However, as of May '24, all cameras sold are PCIe 3.0 protocol, and can't utilize the full performance of PCle4.0. Our detailed data are all real-world tests, but please note that.
1:If you use an adapter card directly into the motherboard PCle4.0 slot test, the memory card will run on PCle4.0 so you can play the memory card maximum performance.
2:If you use Thunderbolt 4/USB4 card reader, you need to PCIe4.0 to USB, there may be 10% loss, the specific performance will vary according to the test platform.
3:If you use a normal USB3.1GEN2 card reader, the speed will not be fast because of the PCle3.0x1 to USB, the theoretical bandwidth of 984.6MB/S.
4: If it is inserted in the USB3.0/USB3.2 GEN1 interface, no matter what the speed of the card reader will be limited by the USB3.0 interface, the speed will not exceed 400MB / S. Therefore, the final speed of the memory card is a bucket effect, where there is a short board where the bottleneck will become.

A: First of all, it is recommended that tablets and cell phones are TypeC interface, and secondly, it is necessary for the device power supply to meet the requirements of the card reader. Generally speaking, the new Android flagships can be supported with a high probability, and IPHONE can be supported starting from the 15th generation, and the IPAD with C port can be supported as well.

A: The 13th and 14th generation IPHONE or early IPAD are LIGHTNING interface, which can't support card reader due to the limitation of power consumption, but the 15th generation IPHONE is TypeC interface, so it can support this card reader.

A: After our R&D evaluation, 512GB full capacity production can not meet the Association's VPG400 certification and performance requirements, so in order to meet the Association's VPG400 certification requirements, as well as the life, performance, data reliability, we ultimately decided to make half of the capacity of the OP space (0ver-provisioning) Although this move will bring a substantial increase in cost, the final product experience will also be greatly improved. Although this will bring a significant cost increase, the final product experience will also be greatly improved.

A:Gold Edition CFA4.0 adopts COB one-piece package, so the strength is higher, and at the same time to meet the IP68 grade waterproofing its own protocol is updated to PCle4.0, so the performance has a double enhancement, and at the same time, the updated 12nm process and larger OP space will be for the power consumption, performance, and life expectancy will have a great deal of improvement.

A: For example, with 8K RAW on the R5, a 512GB card can store only about 24 minutes of footage, while a 1TB card can store around 48 minutes. Therefore, if you have high-bitrate video recording needs, we generally recommend starting with a 512GB card. However, if you are just doing regular photography, a 128GB or 256GB card should be sufficient.

A: The Gold version offers excellent performance, meeting the high specifications required for demanding recording needs, including 8.3K 60P NRAW quality for the Z9, as well as 8K recording for the R5, R5C, and RED VV. Additionally, the Gold version has low power consumption and maintains stable full-card speeds, supporting recording until the card is full.

A: Sorry, we do not comment on competitors' products, as they are respected counterparts. We recommend purchasing our product for your own comparison. We offer a 7-day no-reason return policy, so if you are not satisfied with our product, you can return it.

A: Sorry, we do not make such absolute guarantees. Although the overall failure rate of our memory cards is very low, we cannot guarantee that they will never encounter issues. Without being able to predict the exact cause of any potential problems, we cannot offer a 100% data recovery guarantee. However, if you do encounter such difficult issues, we will make every effort to attempt data recovery, and this service is provided free of charge.

A: Our memory cards are compatible with the vast majority of currently available cameras and do not have compatibility issues. Additionally, we continuously update and improve the firmware of the cards to better support newly released cameras. For a detailed list of supported models, please refer to the information at the beginning or contact customer service.

A: USB4 card readers can maximize the performance of memory cards, but because USB4 card readers are expensive, we recommend that users who are not particularly sensitive to the speed of USB3.1 card readers can meet their daily needs. Most of the other card readers on the market are compatible with this Gold CFA4.0 card, please consult the corresponding merchants for specific card reader speed and compatibility.

A: Other brands' CFexpress card readers should theoretically be compatible with our memory cards, but actual performance may vary, and we cannot guarantee 100% compatibility. XQD card readers, in theory, cannot support CFexpress memory cards. Our memory cards have high performance, so some heat generation is inevitable during operation. However, we have optimized the algorithm protocol and power DCDC to ensure that, compared to other products, our cards generate relatively low heat.

A: We are a senior council member of the global CFA organization (https://compactfash.org), which is responsible for setting the CFexpress standards. Each of our memory card products undergoes testing and certification by the CFA association, so you can be assured of their quality and compatibility.

A: CFexpress memory cards come with a lifetime warranty and have no write limit. Card readers come with a 1-year warranty. For qualit y issues within 30 days of the order, we will cover the round-trip shipping costs. After 30 days, shipping costs will be shared. Please note that issues caused by user actions such as disassembly, repair, bending, deformation, or water damage will void the warranty.
