256GB microSDXC Elite for Android

The Team Group Elite microSDXC card offers 256GB of storage built to the UHS-I U3 V30 A1 specification. It targets Android smartphones and tablets that need fast app loading and 4K UHD video recording. The A1 rating guarantees random read and write performance of 1500 and 500 IOPS respectively.

Capacity and sustained speed headroom

Sequential read reaches 100MB/s and write reaches 50MB/s, while the V30 rating ensures a minimum sustained write of 30MB/s for uninterrupted 4K capture. The 256GB capacity holds hours of high-bitrate footage or large app libraries, though extended 8K or high-frame-rate workflows would exceed the guaranteed write floor.

Build integration and durability

The card includes a full-size SD adapter for direct camera or laptop slot use. It meets the SD 5.1 specification and is rated waterproof, dustproof and x-ray proof for rugged mobile use. Devices without a microSD slot or those requiring UHS-II or higher bus speeds cannot take advantage of this card.

Questions about this item

Will this 256GB microSDXC UHS-I card work in my older camera that only supports standard SDHC cards?

The card is microSDXC format and requires a device that supports the exFAT file system and UHS-I speeds. An SD adapter is included, but the host device must explicitly support SDXC capacity.

How can I verify the card delivers the rated 100MB/s read and 50MB/s write performance after formatting?

Run a benchmark tool such as CrystalDiskMark or ATTO using a UHS-I card reader; sequential results should approach 100 MB/s read and 50 MB/s write, while random 4K IOPS should reach 1500 read and 500 write.

Does the package include the SD adapter or must I buy it separately?

The retail box contains the 256GB microSDXC card and a full-size SD adapter; no additional accessories are required for use in SD slots.
