Frequently Asked Questions: High Speed Memory Card

What is a high speed memory card?

A high speed memory card is a storage device designed for rapid data transfer and sustained write speeds necessary for professional photography and videography. These cards typically feature read speeds exceeding 100 MB/s and write speeds above 90 MB/s. KingSpec's CFast memory cards deliver professional-grade performance with speeds up to 570 MB/s read and 530 MB/s write for demanding applications.

What is the fastest memory card speed?

The fastest memory card speeds vary by format. KingSpec's CFast memory cards achieve up to 570 MB/s read and 530 MB/s write speeds using SATA III 6Gbps interface. These speeds are sufficient for 4K UHD video recording at 30fps and professional photography workflows. The actual fastest speed depends on the card format, with CFast cards offering excellent performance for cinema cameras.

Does a 2TB micro SD card exist?

Yes, 2TB microSD cards do exist, though they represent the current maximum capacity available in the microSD format. These ultra-high-capacity cards are ideal for extended recording sessions, large photo libraries, and applications requiring substantial portable storage. For professional video work, CFast cards up to 1TB offer superior speed and reliability compared to microSD options.

How to know if an SD card is high speed?

Check the speed class ratings printed on the card: U3 (minimum 30 MB/s write), V30/V60/V90 (video speed class), or numbered class inside the "C" symbol. Look for UHS-I, UHS-II, or UHS-III markings indicating bus interface speed. For CFast cards, look for specific read/write speed specifications listed on the packaging, like KingSpec's 570/530 MB/s ratings for guaranteed professional performance.
