Apps work with ease – Conforms to the new A1 standard
Application Performance Class 1 (A1)
The A1 standards state that an SD card must provide a random read speed over 1500 IOPS, a random write speed over 500 IOPS, and a sustained sequential write speed of at least 10 MB/s.
As a result, the speed of starting up smartphone apps and reading data with a photo app is stabilized, making the use of smartphones more comfortable.
Transfer at a speed of up to 104 MB/s! Supports UHS Speed Class
Compatible with UHS-I, an interface that achieves high-speed, stable transfer. It can read and write at a speed of up to 104 MB/s (standard rate) and meet the need for handling large volumes at high speed. It is also UHS Speed Class 1-ready, guaranteeing a transfer speed of 10MB/s for UHS compatible devices.
What’s a UHS-I?
Although a UHS-I interface memory card can work with non-compatible devices, it performs best when used with UHS-I interface compatible devices.
Supports UHS Speed Class 1
Among the UHS-I standards, it supports Speed Class 1. It also supports Class 10, with both guaranteeing a transfer speed of 10 MB/s.
