Samsung PRO Plus 256GB microSDXC

The Samsung PRO Plus is a 256GB microSDXC card rated UHS-I U3 V30 A2 for sustained write performance. It targets photographers and videographers who need reliable capture of 4K footage and high-volume stills. The card is sold new and ships from Japan. It is not suited for dash-cam or surveillance loops where continuous overwrite is required.

Installation and common issues

Insert the card into any compatible microSDXC slot or reader; no drivers are needed. Maximum read reaches 160MB/s and write reaches 120MB/s when the host device supports UHS-I speeds. A frequent mistake is using an older reader or USB 2.0 port, which caps transfer well below the rated figures. The card carries Class 10, U3 and V30 markings to confirm minimum sustained write.

U3 V30 A2 speed class

The U3 and V30 ratings guarantee a minimum sequential write of 30MB/s, which is the single spec that decides if 4K recording will drop frames. A2 application performance adds faster random I/O for app loading on phones or tablets. If your workflow demands higher sustained write or a different capacity, this card will not meet that need.

商品問答

How can I confirm the card is delivering the rated 160 MB/s read and 120 MB/s write speeds after setup?

Use a compatible UHS-I reader and run a benchmark tool such as CrystalDiskMark; sustained sequential results near 160 MB/s read and 120 MB/s write indicate the card is performing to spec.

What comes in the package and do I need to buy a reader separately?

The box contains the 256 GB microSDXC card only; a UHS-I card reader is not included and must be purchased separately to achieve the quoted transfer rates.

Which capacity and speed class should I choose for 4K video and app-heavy use?

The 256 GB model with U3, V30 and A2 ratings is designed for smooth 4K capture and fast app loading, making it the appropriate single option listed.
