The Silicon Power Superior is a UHS-I microSD card with an A2 app-performance rating and V30 video speed class. It is rated for read speeds up to 100 MB/s and write speeds up to 80 MB/s, which is enough for 4K recording in phones, action cameras, drones and the Switch. The A2 rating (4,000 random read and 2,000 random write IOPS) is the feature that sets it apart from plain U1 cards, since it speeds up app installs and loading on Android devices. Owners rate it highly for value and reliability, though it is a UHS-I card, so it trails UHS-II and newer U3 cards in sustained write speed for heavy burst shooting.

The Silicon Power Superior is a microSDXC UHS-I memory card that comes with an adapter. It has an A2 rating for running apps, with a minimum random read of 4,000 IOPS and a minimum random write of 2,000 IOPS. Using it for apps also saves internal storage space on Android smartphones, tablets, and other mobile devices that run apps.
The card has UHS Speed Class 1 (U3) and UHS Video Speed Class 30 (V30) ratings for recording 4K Ultra HD video. Read speeds go up to 100 MB/s and write speeds up to 80 MB/s. It can be used in digital cameras, smartphones, drones, portable game consoles, and tablets. At 256GB, it holds up to 39,400 songs, 75,200 photos, or 12 hours of 4K Ultra HD video.
The card resists water and shock, and it is immune to airport X-rays. It can be stored at temperatures from -40°C to 85°C. It works with microSDHC-enabled host devices, but not with SD devices or SD readers. Some of the listed capacity is used for formatting and other functions, so the actual storage space is less than listed.
