Built for continuous recording

This microSDXC card is designed for dash cams and security systems that write video around the clock. It carries Class 10, U3 and V30 ratings so it can sustain Full HD and 4K capture without dropping frames. The 64GB capacity stores hours of footage before the oldest files are overwritten. An SD adapter is included for use in full-size slots.

Endurance under constant rewrite cycles

The card is rated for up to 20,000 hours of continuous recording and re-recording. It operates reliably in extreme heat and freezing cold, and it is shockproof, waterproof and x-ray proof. Read speeds reach 100MB/s while write speeds hit 40MB/s, allowing fast offload of saved clips. These figures reflect sustained performance rather than short burst peaks.

V30 sustained write guarantee

The Video Speed Class 30 rating guarantees a minimum sequential write speed of 30MB/s, which is the single specification that determines whether the card can keep up with your camera's bitrate. If your device requires a higher sustained write class, this card will not meet that need.

Questions about this item

How much power does the 64GB microSDXC card draw during continuous 40MB/s write cycles?

The card draws minimal power from the host device during sustained writes; microSD cards have no separate power supply and consume only what the slot provides for flash operations.

What host device and file system are required for the U3 V30 speed ratings to work?

A device with a UHS-I microSDXC slot and exFAT formatting is needed; the card includes a microSD-to-SD adapter for full-size slots.

Will the Class 10 U3 card maintain 30MB/s minimum write speed in an older dash cam that only supports Class 10?

Yes, the card is backward compatible and will sustain at least Class 10 (10MB/s) write speeds in older hosts; U3/V30 minimums require a UHS-I capable device.
