SanDisk Extreme PRO microSDXC V30 vs ADATA Premier Pro microSDXC 256GB

Buy the SanDisk Extreme PRO if you shoot 4K video, burst photos or run apps from the card; its 200MB/s read and 90MB/s write speeds are roughly double the ADATA's 100MB/s read and 80MB/s write. The ADATA Premier Pro is a solid A2/V30 card for drones, dash cams and phones where sustained write speed matters less than capacity. Both are 256GB microSDXC UHS-I cards with A2 and V30 ratings, so both handle 4K recording and app installs, but the SanDisk is the faster and more proven card.

• Choose the SanDisk Extreme PRO if you move large files often, shoot high-bitrate 4K or want the faster card for a drone, action camera or Raspberry Pi.
• Choose the ADATA Premier Pro if you need a dependable 256GB A2/V30 card for a phone, dash cam or media player and speed is not the bottleneck.
