Kodak microSD 64GB 4K compatible (entry-level) How about it for your first 4K shooting experience? Kodak is famous as an analog camera manufacturer, but it was also the first manufacturer to make a digital camera. It has sufficient speed for an entry-level card, making it perfect for your first 4K shooting experience. One card has been opened to confirm operation, capacity, and speed. I think it's reassuring to know the actual measured values. Second card: Capacity check Using the standard software H2testw, I confirmed that there is no falsification and that the capacity is as stated on the package. Third card: Speed measurement with a Kodak adapter and a cheap card reader. Fourth card: Speed measurement using a UHS-II standard adapter and card reader. ★ The slow speed of H2testw is because this software eliminates the cache effect and measures the actual capacity. In contrast, the speed measurement software CrystalDiskMark incorporates the cache effect to measure speed, so there is a difference between the two software. The purposes of each software are different. However, since this is an entry-level card, please do not have excessive expectations. In the case of long-time shooting, there is a possibility that a delay will occur due to insufficient cache. ★ Compatibility with your equipment may vary, so returns are generally not accepted. It is also normal for PC parts stores not to offer compatibility guarantees.
