Capacity and speed class

The Ackmioxy 512GB Extreme microSDHC UHS-I card delivers 512GB of storage with a UHS-I interface. It carries C10, U3, V30 and A2 ratings, supporting sustained write speeds for 4K video and fast app performance. The bundled adapter allows use in full-size SD slots.

Build integration

The microSD form factor fits action cameras, drones, pocket cinema cameras and mobile devices with a microSD slot. The UHS-I bus works with existing host controllers, so no special hardware is required. The adapter frees up the card for use in laptops or card readers that only accept full-size SD.

Upgrade path

This card replaces lower-capacity microSD cards such as 32GB, 64GB, 128GB or 256GB models when longer recording time or more burst shots are needed. The jump is worth it when current cards fill up during 4K sessions or when app load times feel slow on A1-rated media.

Perguntas sobre este artigo

Will the 100MB/s read speed hold steady during long 4K recording sessions?

The card is rated U3 and V30, which guarantee a minimum sustained write speed of 30MB/s for continuous 4K capture.

Does the card run hot or draw extra power when recording all day?

MicroSD cards have no moving parts and consume very little power, so heat and noise stay negligible during extended use.

What device slot or adapter is required to use this 512GB card?

Your device must accept microSDXC cards up to 512GB; a full-size SD adapter is included for slots that need it.
