Expand the onboard storage of mobile devices, such as smartphones, tablets, action cameras, drones, and more with the 256GB Premier-X UHS-I microSDXC Memory Card with SD Adapter from PNY Technologies, which will help free up space so you can enjoy more digital content. This card provides up to 256GB of space for HD photography, photo bursts, and 4K Ultra HD videography at resolutions up to 4096 x 3072. It is compatible with the UHS-I bus and features a speed class rating of V30 / U3, which guarantees minimum write speeds of 30 MB/s. If your device doesn't support the V30 or U3 ratings, this card is compatible with the Class 10 standard, meaning that write speeds won't drop below 10 MB/s. Additionally, read speeds are supported up to 100 MB/s.

Also notable is A1 App Performance, which enables apps to run directly from the microSD card. This delivers faster app launches and performance, with read speeds of up to 1500 IOPS and write speeds of up to 500 IOPS.

As with many PNY cards, this is media shockproof, waterproof, temperature proof, and magnet-proof. Included is a microSD to SD adapter, allowing this card to be used in SD-compatible devices, including DSLR cameras, video cameras, desktops, and laptops.
