SanDisk Extreme PRO microSDXC 512GB vs SanDisk Extreme microSDXC 512GB

Both are 512GB SanDisk microSDXC cards rated U3, V30 and A2, so they handle 4K video and app-heavy phones alike. The Extreme PRO is the faster card on paper: up to 200MB/s read and 140MB/s write versus the Extreme's lower rated speeds, which matters for burst shooting, drone footage and moving large files. Build and durability claims are similar, and both carry the same red-and-gold SanDisk look. Buy the PRO if you shoot 4K or high-bitrate footage and want headroom; the plain Extreme is the sensible pick if you mostly store photos, music and apps and want to spend less.

• Choose the SanDisk Extreme PRO if you record 4K or high-bitrate video on a drone, action camera or phone and want the fastest sustained writes SanDisk offers in this class.
• Choose the SanDisk Extreme if you need 512GB for photos, music, apps or 1080p video and don't need the PRO's extra write headroom.
