Understanding UHS-I

UHS-I is the new standard for higher-speed bus interfaces defined by the SD Association as part of the SD Memory Card Specification Ver. 3.01, which provides up to 104 MB/s performance.
Because of the ultra high speed of data read and write processes, UHS-I allows for faster high resolution image processing on DSLR. Its rapid burst of high-resolution photos enhances continuous shooting with dynamic cameras, and effectively reduces the transfer time for large files between the shooting device and your computer.

What does UHS Speed Class mean?

How do you choose the most suitable memory card for your photo or video recording device? First of all, you need to identify the best performance of the different memory cards available. Speed Class and UHS Speed Class* symbols indicate minimum video recording performance to ensure smooth video playback. This is important for camcorders, video recorders and other devices with video recording capabilities.




 

Bus Mode Bus Speed Speed class
UHS-I ( Ultra High Speed ) UP to 104 MB/s UHS Speed Class 1
Conventional
( High Speed or Default Speed )
Up to 25 MB/s Speed Class 2, 4, 6, 10
( Higher Speed Class covers lower class performance )

Speed Class and the UHS Speed Class are two different ratings. The Speed Classes defined by the SD Association are Class 2, 4, 6 and 10. UHS Speed Class 1 is designed for UHS* devices only.

* UHS (Ultra High Speed), the fastest performance category available today, defines bus-interface speeds up to 312 Megabytes per second for greater device performance. It is available on SDXC and SDHC memory cards and devices.
