Capacity and compatibility

This SanDisk Ultra microSDXC card provides 256GB of storage for Android smartphones, tablets and MIL cameras. It uses the UHS-I interface and includes a full-size SD adapter for broader device support. The A1 rating means apps stored on the card can launch and run faster than on standard cards. Read speeds reach up to 120MB/s with compatible hardware.

Best fit and limits

The card suits users who want more space for Full HD video, photos and apps on mobile devices or entry-level cameras. Buyers who need sustained write performance for 4K recording or professional workflows should consider cards with higher speed class ratings. Write speeds are lower than the quoted read maximum and vary by host device.

Deciding specification

The A1 application performance class guarantees a minimum of 1500 read IOPS and 500 write IOPS for smoother app loading. Combined with U1 and Class 10 ratings, it ensures a baseline for Full HD capture. Verify that your device supports UHS-I speeds above 104MB/s to benefit from the 120MB/s peak read rate.

Questions about this item

How much power does the 120MB/s microSDXC card draw when recording Full HD video all day?

Memory cards draw negligible power from the host device; the 120MB/s read rating and U1 speed class do not indicate a specific wattage figure.

Which adapter or reader must I already own to reach the 120MB/s transfer rate?

A USB 3.0 card reader is required to achieve the quoted 120MB/s read speed; the included microSD-to-SD adapter works with any standard SD slot.

Will the A1-rated 1500 read IOPS performance work in my older camera that only supports UHS-I?

Yes, the card is UHS-I U1 and Class 10 compatible, so it functions in older UHS-I cameras, though A1 app-loading speeds depend on host support.
