128GB microSDXC for action capture

This SanDisk Extreme PRO card delivers 128GB of UHS-I storage rated U3, V30 and A2. It targets drone pilots, action-camera users and Android handheld gamers who need sustained write performance for 4K UHD video and fast app loading. The A2 rating means installed applications launch and run more smoothly on compatible devices.

QuickFlow offload and bundled adapter

SanDisk QuickFlow technology accelerates file transfers when the card is paired with a supported reader, reaching the quoted 250MB/s read ceiling. A full-size SD adapter is included so the microSDXC card can slot directly into cameras, laptops or card readers that only accept the larger form factor.

Handles 4K UHD and heavy app loads

Sequential write speeds up to 120MB/s sustain 4K UHD recording without dropped frames, while the V30 guarantee covers continuous 30MB/s capture. The 128GB capacity fills quickly during extended 5K point-of-view sessions or large game installs, so creators planning multi-day shoots or sizable libraries should consider larger cards.

Questions about this item

How often will the microSDXC card itself need to be replaced under normal use?

The card is waterproof, humidity proof, shock proof, X-ray proof and magnet proof, so it resists the environmental damage that usually forces replacement.

What limit appears first during sustained 4K UHD video recording?

The write speed ceiling of up to 120MB/s will be reached before the 250MB/s read limit when capturing continuous high-bitrate footage.

How much heat or power draw should I expect when the card runs all day in a drone?

The card has no moving parts and draws minimal power from the host device, producing negligible heat during extended read or write sessions.
