High-end Memory Card Buying Guide (CFexpress, SD V90, SD V60)
To do a good job, an artisan needs the best tools. Creators must first get to know their tools at hand at the first stage of the creative process. In addition to a high-end camera, top memory cards for the camera also play a crucial role for creators. Creators usually impose specific requirements for the capacity and specifications of memory cards. What should we pay attention to when buying high-end memory cards? I have organized the relevant knowledge and will share them with you today!

CFexpress Card
CFexpress cards use PCIe 3.0 interface, offering higher transfer speeds. CFexpress cards are larger than typical SD cards, allowing larger capacities in TB grade. CFexpress cards are often suitable for creators using filmmaking video cameras or single-lens reflex cameras. These filmmaking video cameras or single-lens reflex cameras that are compatible with CFexpress cards can produce the resolution required in microfilms that have started a few years ago or well-known blockbusters shown in theater chains.
SD Card
According to the SD Association, there are four capacity specifications of SD Cards:
| Type | Storage Capacity |
| SD | 2GB and below |
| SDHC | more than 2GB and up to 32GB |
| SDXC | more than 32GB and up to 2TB |
| SDUC | more than 2TB and up to 128TB |
Hardware devices that can load memory cards are backward-compatible. For example, SDXC-compatible devices can use and support SDXC, SDHC, and SD cards. SDHC-compatible devices can use and support both SD and SDHC memory cards but not SDXC cards.
High-end SD cards have a large capacity and excellent read/write speed. The read speed is related to file transfer and data backup, while the write speed is associated with high-end cameras' burst mode and photography features. For example, I compared the T-CREATE EXPERT SDXC UHS-II U3 V60 and V90 memory cards. The V90 is faster compared to the V60. Next, take as an example two YouTube creators - A and B. Creator A usually films travel vlogs, therefore T-CREATE EXPERT SDXC UHS-II U3 V60 is suitable for this type of creation demand. While creator B needs to make large and ultra-high-quality content, thus T-CREATE EXPERT SDXC UHS-II U3 V90 having a higher speed can allow creators to record videos in high quality.
Creators should pick out suitable high-end memory cards by considering their creation demands and camera compatibility in terms of speed. I hope that this simple summary on memory card selection is helpful for you.
