High-capacity microSDXC for creators

The DATO Lightning 512GB microSDXC card targets photographers, videographers and portable gamers who need generous storage in a tiny form factor. It carries UHS-II, U3, V60 and A1 ratings, signalling readiness for 4K capture and app-heavy workloads. The 512GB capacity holds hours of high-resolution footage or a full game library.

UHS-II slot required for peak speed

To reach the quoted 280MB/s read and 180MB/s write figures, the host must provide a UHS-II microSD slot; in UHS-I devices the card falls back to the lower bus speed. No extra power adapter or cable is involved — the card draws directly from the slot. Its 0.59" height and 1-gram weight add virtually no bulk to cameras, phones or handheld consoles.

Sustained 60MB/s write floor for long takes

The V60 classification guarantees a minimum sequential write of 60MB/s, so 4K recording remains stable across extended clips without frame drops. A1 rating also means consistent random read and write for installed applications and game assets. Performance holds steady under continuous load rather than peaking only in short bursts.

Questions about this item

What sustained write speed does the V60 rating guarantee on this 512GB card?

The V60 video speed class ensures a minimum sustained write speed of 60MB/s, which is the limiting factor during long 4K recording sessions.

How much power does the UHS-II interface draw when the card runs continuously in a camera or handheld console?

The microSDXC form factor draws very little power; at 1 gram weight and 0.04" depth the card adds negligible heat or battery drain during all-day use.

Which host specification must my device already support to reach the 280MB/s read and 180MB/s write figures?

Your device needs a UHS-II microSDXC slot; the card is backward compatible with UHS-I slots but will then operate at lower speeds.
