128GB microSDXC for Action Cameras

This SanDisk Extreme Pro card delivers 128GB of storage in the microSDXC form factor. It is built for action cameras, interchangeable-lens cameras, drones, smartphones and tablets that accept microSDHC or microSDXC media. The A2 rating supports faster app loading on compatible mobile devices. Buyers who need capacities beyond 128GB or cards rated for sustained write speeds above 90MB/s should consider other options.

UHS-I Interface with SD Adapter Included

The card uses the UHS-I bus and carries V30, U3 and Class 10 markings for minimum sustained write performance. An SD adapter is supplied so the same card can slot into full-size SD readers or cameras. Host devices must support microSDHC or microSDXC UHS-I to reach the quoted transfer rates; older non-UHS slots will fall back to slower speeds. No external power or special drivers are required.

Rated for -25°C to 85°C Operation

Operating temperature range spans -25°C to 85°C, while storage tolerance extends to -40°C. The tiny 1.02 mm thickness and 10.92 mm by 14.99 mm footprint mean the card adds negligible bulk inside sealed camera housings. With no moving parts, silent operation is guaranteed. Power draw scales with the host device's UHS-I implementation and is not separately specified.

Questions about this item

How long can the card sustain 90MB/s writes before thermal throttling reduces speed?

The card is rated for continuous operation up to 85 °C; sustained 90MB/s writes will not exceed this limit under normal workloads.

Does the card generate noticeable heat or draw extra power during all-day 4K recording?

Operating temperature range is -25 °C to 85 °C with no active cooling; power draw stays within standard UHS-I limits.

Which host devices can actually use the 170MB/s read speed with the included adapter?

Any device with a UHS-I microSDXC or full-size SDXC slot — action cameras, drones, mirrorless cameras, smartphones and tablets — will reach the rated read speed.
