Extreme 2TB microSDHC UHS-I card

The Ackmioxy Extreme card provides 2TB of storage in a microSDHC form factor with a UHS-I interface. It carries C10, U3, V30 and A2 ratings, supporting 4K video capture and fast app loading. A full-size SD adapter is included for broader device use. The card is supplied new and ready for immediate deployment.

Suits 4K action cameras and drones

This card fits creators recording 4K footage on devices such as DJI Osmo, Insta360 or GoPro units that accept microSDXC media. The A2 rating helps with app performance on compatible handhelds. Buyers needing sustained write speeds above 100MB/s or capacities beyond 2TB should consider alternative formats. The UHS-I bus limits peak throughput for high-bitrate 8K workflows.

Simple drop-in installation

Insert the card into the device slot or the supplied adapter until it clicks; most cameras and drones recognise it automatically. A quick format in the host device prepares the file system for optimal performance. The most common issue is using a legacy reader that caps speed at UHS-I defaults, which reduces transfer rates. Counterfeit cards with mislabelled capacity can also cause data loss.

Questions about this item

What minimum UHS speed class must my device support to use the 100 MB/s read speed of this 2 TB card?

Your device must support UHS-I with U3 or V30 rating to reach the advertised 100 MB/s read performance.

Will this 2 TB microSDXC card work in my older camera that only takes microSDHC cards up to 32 GB?

No, the 2 TB capacity uses the microSDXC standard, which requires a device explicitly compatible with microSDXC.

After formatting, how can I verify the card delivers its rated A2 application performance?

Run a benchmark that measures random 4 KB read/write IOPS; sustained figures above the A2 threshold confirm the card is working as intended.
