128 GB microSDXC for 4K video and apps

This Samsung PRO Plus microSDXC card provides 128 GB of storage for devices that accept microSD media. It targets users who record 4K video or run applications directly from the card. The A2 rating means random read and write performance is suitable for app workloads. Buyers needing larger capacities or different form factors should look elsewhere.

UHS-I interface limits peak throughput

The card uses a UHS-I interface, so maximum sequential speeds top out at 160 MB/s read and 120 MB/s write when paired with a compatible reader. Real-world throughput will be lower on hosts that do not support the UHS-I bus. Sustained write speed is guaranteed at 30 MB/s by the V30 and U3 ratings. Devices limited to older bus modes will not reach the advertised peaks.

V30 sustained write decides 4K suitability

The V30 marking guarantees a minimum sequential write speed of 30 MB/s, which is the single specification that determines whether the card can keep up with 4K video recording. If your camera or recorder requires a higher sustained write rate, this card will not meet that requirement. For standard 4K capture at typical bit-rates the V30 rating is sufficient.

商品問答

Should I pick the 128 GB model or a larger capacity?

The 128 GB card stores roughly 4 hours of 4K footage or thousands of high-resolution photos, matching the capacity shown in the product name.

What do the 160 MB/s read and 120 MB/s write figures mean in daily use?

They are peak speeds reached with a compatible UHS-I reader; real-world transfers of large video files will be close to these numbers, while mixed small files run slower.

How does the UHS-I U3 V30 A2 rating affect what I can record?

It guarantees a minimum 30 MB/s sustained write for smooth 4K video and meets the A2 spec for faster app loading on supported devices.
