128GB microSDXC for action and drone cameras

This SanDisk Extreme card delivers 128GB of storage for devices that use the microSDXC format. It targets photographers and videographers who need reliable capacity for 4K UHD and Full HD recording. The A2 rating supports quicker app loading on compatible Android devices. It suits anyone capturing high-bitrate footage in the field.

UHS-I U3 V30 rated with bundled adapter

The card carries Class 10, UHS Speed Class 3 and Video Speed Class 30 ratings, sustaining a minimum sequential write of 30MB/s for uninterrupted video. Maximum read reaches 160MB/s and write reaches 90MB/s on hosts that support those speeds. A full-size SD adapter is included for direct laptop or reader slots. The construction is temperature-proof, water-proof, shock-proof and x-ray proof.

Replaces slower Class 10 or U1 cards

Stepping up from a basic Class 10 or U1 card removes the bottleneck that causes dropped frames or long buffer clears during 4K capture. The jump is worth it when your camera writes at sustained rates above 30MB/s or when you offload large batches and want the 160MB/s read ceiling. Users who only shoot stills or 1080p at low bitrates will not see a practical benefit.

Questions about this item

What UHS-I bus speed does the SDSQXA1-128G-GN6MA use and what maximum read rate does it allow?

The card uses the UHS-I interface, which caps practical read throughput at the rated 160MB/s when the host device supports that speed.

What physical adapter is included so the microSDXC card fits standard SD slots?

A full-size SD adapter is supplied, letting the 128GB microSDXC card work in cameras, laptops or readers that only accept regular SD cards.

How do you enable the A2 app-performance rating on the card, and what step is often missed?

Insert the card, format it in the device, then install the SanDisk Memory Zone app from Google Play; skipping the in-device format prevents the A2 benefits from activating.
