At the moment, not all devices around are A2 compatible, so please make sure that the device you are using the card with supports the A2 speed class, which specifies a minimum random read speed of 4000 IOPS and write speed of 2000 IOPS. If the device is not compatible, the performance of the card will not meet A2 specifications.
