1TB microSD for action cameras and drones

The SanDisk Extreme microSD UHS-I card delivers 1TB of capacity for creators who shoot 5.3K point-of-view footage and 4K UHD aerial video. Rated A2, U3 and V30, it supports rapid app loading on Android devices and handheld consoles while sustaining the write performance needed for continuous burst stills and slow-motion Full HD capture.

Sustained write performance for long sessions

Sequential write speeds reach up to 170MB/s, allowing the card to maintain throughput during extended recording without the drops seen in lower-rated media. The V30 rating guarantees a minimum 30MB/s sustained write, so 5.3K and 4K UHD streams remain stable from the first frame to the last, and burst photography buffers clear quickly for the next sequence.

Low heat and silent operation in handheld gear

With no moving parts and a UHS-I interface, the card runs cool and completely silent inside action cameras, drones and portable consoles. Power draw stays minimal during both high-speed transfers at up to 245MB/s read and continuous 170MB/s writes, preserving battery life on compact devices and eliminating thermal throttling during back-to-back recording sessions.

Questions about this item

Does the card generate noticeable heat or draw extra power when recording 5.3K video for long sessions?

The card is passive with no moving parts, so it produces minimal heat and draws very little power during sustained 5.3K capture.

What host device slot and speed rating are required to reach the 245MB/s read and 170MB/s write figures?

A microSDXC slot that supports UHS-I and the U3/V30 speed class is needed to achieve the quoted transfer rates.

Will the UHS-I interface work reliably in my older drone that only lists UHS-I support without A2 or V30 logos?

Yes, the card is backward-compatible with any microSDXC UHS-I host; it will operate at the host's maximum supported speed.
