Samsung Evo Plus microSD card Tech specs: Read speed: 100MB/s | Write speed: 60 MB/s | SD Class: 10 | Capacity: 64 GB, 128 GB, 256 GB, 512 GB So, now that slotted Android devices can store and run apps from removable cards, the SD Association has introduced a new specification to enable the best user experience – Application Speed Class 2 (A2). Samsung EVO Select microSD memory card Tech specs: Read speed: Up to 100MB/s | Write speed: 90 MB/s | SD Class:10 | Capacity: 128 GB, 256 GB Capacity: If you do have a lot of photos and videos, a smaller microSD card will not be enough to store all your items, so you would want to look for a larger microSD card, like one with 128 GB or even 1 TB if you need it. For the time being, not really. However, this could change in the future if cameras turn out to expand into more app-heavy devices. If this happens then perhaps it will be more relevant to them someday.In some cases, these operating systems allow apps and additional data to be stored on a microSD card. For this reason, the Application Performance Class was introduced to ensure the smooth running and loading of apps. Application Speed Class 2, defines the minimum specification for cards and host devices. Sequential read and write speeds are now joined in importance by random read/write speeds (measured in IOPS). The higher the IOPS (Input/Output operations Per Second) the smaller files can be read and written to the card in any one time. So, for apps that open multiple small files – high scores, different graphics for a single level, licensing permissions, etc. – a minimum IOPS level is important, which is covered by the A2 spec. The SD Association states, “The Application Performance Class was introduced to realize comfortable application manipulation such as compilation of data which is stored in an SD memory card.” https://www.mymemory.co.uk/blog/wp-content/uploads/2018/09/CRP18_SanDisk_MicroSD_A2_Animation_4K-2.mp4

Simply put, there are different speed classes for microSD cards, dependent on how big of capacity your handling and what type of performance you require. Application Performance Class is one of these categories, developed to certify that microSD cards incorporated within Android’s storage capacity, could endure the performance needed to manage numerous applications from the microSD card directly. From this diagram, and in reference to IOPS, it is clear to see that the A2 provides an extraordinary gain. The minimum read performance is up by 2.7x, at the same time as providing 4x faster minimum write speeds. Sandisk Extreme Plus 1TB microSDXC memory card Tech specs: Read speed:Up to 200MB/s | Write speed:90 MB/s | SD Class:10 | Capacity: 1 TB Since Apple’s IOS and Google’s Android operating systems hit the mobile technology market over 10 years ago, being able to give users the ability to add or remove additional storage capacity when desired, has been a major difference between the two systems. A microSD card slot is offered in various devices which operate using Android, allowing users to add an adjustable quantity of storage. Thanks to Android’s adoptable storage device capability, microSD cards have rapidly been adopted by users globally. A2: “The Application Performance Class 2 (A2) is defined by SD Physical 6.0 specification. It makes SD memory card much higher performance than the A1 performance by using functions of Command Queuing and Cache. ”Gigastone: 4K Camera Pro A2V30 Series, 4K Camera Pro A2V60 Series, 4K Camera Extreme A2V90 Series: 64/128/256GB/1TB https://www.mymemory.co.uk/blog/wp-content/uploads/2018/09/New-A2-App-Performance-Class.mp4 Is the Application Performance Class Specification relevant to cameras?

However, if your device requires a lower speed class, shop for microSD cards that have a Class 2, 4, or 6 classification.
