SanDisk Extreme PRO microSDXC 512GB vs SanDisk 512GB Ultra microSDXC Card

Buy the Extreme PRO if you record 4K video, shoot bursts, or run apps from the card. Its V30, U3 and A2 ratings and faster write speeds handle sustained video and app data that the Ultra is not built for. The Ultra is the safer pick for phones, tablets, music and photo storage where capacity matters more than speed. Owners rate the Ultra very highly for everyday use; the Extreme PRO's lower rating reflects a smaller sample and some reports of cards failing early, so buy from a reputable seller and test the card on arrival.

  • Choose the Extreme PRO if you shoot 4K video on a drone or action camera, use a Raspberry Pi, or need fast app performance.
  • Choose the Ultra if you mainly expand phone or tablet storage with photos, music and documents and want the card most owners are happy with.

Questions and answers

Which card is better for 4K video?
The Extreme PRO. Its V30 and U3 ratings guarantee the sustained write speed 4K recording needs. The Ultra is only Class 10 and may drop frames.
Which lasts longer?
Both are SanDisk cards with similar build, but the Extreme PRO adds waterproof, shock, temperature and X-ray ratings. Owner ratings favor the Ultra, though the Extreme PRO's sample is much smaller.
Is the Extreme PRO worth stepping up to?
Yes if you record video, shoot bursts or run apps from the card. For phone photos and music, the Ultra does the job and owners report fewer problems.
Will either work in a phone or tablet?
Both are microSDXC, so check your device supports 512GB cards. The Extreme PRO's A2 rating helps if you store apps on the card.
Why is the Ultra rated so much higher?
It has 1,200 ratings against 57 for the Extreme PRO, and most Ultra buyers use it for simple storage where it performs well. Treat the gap as a signal, not a guarantee.
Do I need a special reader for full speed?
The Extreme PRO's 200 MB/s read speed needs a UHS-I reader that supports the higher bus speed. A basic reader will be slower.
