SanDisk Extreme Pro microSDXC vs ADATA microSDXC UHS-I Memory Card

Buy the SanDisk Extreme Pro for action cameras, drones, 4K video and phones that run apps off the card. Its U3/V30 rating and A2 app class are built for sustained high-bitrate writes, and its 4.9 rating across 7,400 reviews is a strong track record. The ADATA is the cheaper-feeling, slower card: U1/V10 and A1 suit dashcams and surveillance recorders that write steadily at lower bitrates. Both are 64 GB microSDXC with UHS-I, so pick by workload, not capacity.

  • Choose the SanDisk Extreme Pro if you shoot 4K or high-frame-rate video, fly a drone, or want apps to load from the card on an Android phone.
  • Choose the ADATA if the card lives in a dashcam or surveillance system doing constant loop recording and you want a bundled SD adapter.

Questions and answers

Which card is better for 4K video?
The SanDisk Extreme Pro. Its V30 rating guarantees sustained write speed for 4K UHD, while the ADATA's V10 rating targets Full HD.
Which lasts longer in a dashcam?
Both are rated for shock, water and X-ray resistance. The ADATA is explicitly marketed for continuous re-recording, but constant loop writing wears any card, so plan to replace either one periodically.
Is the SanDisk worth stepping up to?
Yes if you record 4K, shoot bursts on a drone, or run apps from the card. For a surveillance recorder writing modest bitrates, the ADATA covers the job.
Do both work in the same devices?
Yes. Both are 64 GB microSDXC UHS-I cards, so they fit the same slots. Hosts limited to UHS-I will not reach the SanDisk's top read speed.
Does the ADATA include an adapter?
Yes, it ships with a microSDXC to SD adapter. The SanDisk listing does not state one is included.
Which is better for a phone?
The SanDisk, because its A2 app performance class gives faster random reads and writes for apps installed on the card. The ADATA is A1.
