128 GB microSDXC for 4K and intensive apps

The Samsung Pro Plus 128 GB microSDXC card targets users who need fast, reliable storage for 4K video capture and high-performance gaming on smartphones, tablets, drones or action cameras. Its A2 rating means it can run demanding apps directly from the card. Buyers who only store documents or occasional photos will not benefit from the extra speed.

160 MB/s read and 120 MB/s write headroom

Sequential read reaches 160 MB/s and write up to 120 MB/s, keeping 4K recording smooth and reducing buffer waits during burst shooting. The V30 guarantee sustains at least 30 MB/s continuous write, so bitrate spikes stay handled. Workflows that demand sustained writes above 120 MB/s will hit the card’s ceiling.

V30 and A2 ratings decide fit

The card carries both Video Speed Class 30 and Application Performance Class 2 ratings, the two specifications that determine whether it meets a device’s minimum requirements for 4K recording and app loading. If your hardware requires a higher video class or lacks A2 support, this card will not unlock the needed performance.

Questions about this item

Will the 160 MB/s read speed work with my older UHS-I card reader?

The card is backward compatible with UHS-I readers, but the 160 MB/s read speed requires a UHS-III capable host; older readers will limit transfer rates to their maximum specification.

How can I confirm the V30 and A2 ratings are active after formatting?

Run a sustained write test — 4K video should record without dropped frames and apps loaded from the card should launch quickly, confirming the 30 MB/s minimum write and A2 random IO performance.

Does the package include a full-size SD adapter or only the 128 GB microSDXC card?

Only the microSDXC card is included; a full-size SD adapter must be purchased separately if your device lacks a microSD slot.
