Our take on the SanDisk 512GB Ultra microSD Card

The SanDisk Ultra is a 512GB microSDXC card rated Class 10 and UHS-I, with read speeds up to 100MB/s. That is enough for Full HD video capture and playback on Android phones, tablets and other microSDXC devices, and the card is built to survive shock, water, temperature extremes and X-rays. It is a read-focused card: write speeds are far below the read figure, so it suits storing photos, video and files rather than sustained high-bitrate recording. Rivals in this class, such as Samsung's EVO Select, offer similar capacity and durability with stronger write performance for 4K capture. This version ships without an SD adapter.

Questions and answers

Is this card fast enough for 4K video?
It is rated for Full HD recording and playback. Write speeds are well below the 100MB/s read figure, so sustained 4K capture is not its strength; a card rated U3 or V30 is the safer choice for that.
Will it work in my Android phone or tablet?
Yes, if the device supports microSDXC. Most recent Android phones and tablets with a microSD slot do, and the card is formatted for that standard.
Does it come with an SD adapter?
No. This version is the microSD card only, so it will not fit a full-size SD slot without a separate adapter.
How does it compare with the SanDisk Extreme?
The Ultra is read-focused and cheaper in performance terms, while the Extreme line adds much faster write speeds and higher video speed classes for action cameras and 4K recording.
Is the card waterproof and durable?
SanDisk rates it shockproof, temperature-proof, waterproof and X-ray-proof, so it tolerates tough conditions in phones, tablets and cameras.
What is the actual usable capacity?
The card is 512GB as sold. As with any flash storage, some space is used by formatting, so the free space shown by your device will be slightly less.
Where is the SanDisk 512GB Ultra microSD Card cheapest?
At Amazon, for $139.95, as of our latest check.
